Antimony Tin Oxide ATO Powder CAS 128221-48-7

What is Antimony Tin Oxide ATO Powder ？
Antimony tin oxide, also called antimony doped tin dioxide, abbreviated as ATO. It is a non-resistive transparent conductive material in the semiconductor field. It can be used in various glass, Plastics and various resins play a role in transparency, conductivity, antistatic radiation, ultraviolet, and infrared blocking. Antimony tin oxide nanoparticles have broad application prospects in many fields due to their high conductivity and light color transparency. ATO antimony tin oxide is a new type of functional material that has developed rapidly in recent years.

Antimony tin oxide is a world-recognized excellent material with a series of unique properties. They show good electrical conductivity in antistatic applications and have good infrared absorption capabilities. Strong absorption of near-infrared light occurs, and transparency in the visible light range can be maintained in the film.

ATO Antimony Tin Oxide is a highly insoluble, thermally stable source of aluminum suitable for glass, optical, and ceramic applications. Antimony tin oxide is one of the most commonly used transparent conductive oxides because it has two key properties: optical transparency and conductivity. These characteristics are important for photovoltaic devices, including solar cells and flat-panel displays.

However, the current technology for forming particulate and nanoparticulate tin oxide and using an acidic medium to provide a surface coating, coating acid-sensitive materials with nanoparticulate antimony-doped tin oxide (ATO) films has become very important.

The Antistatic coating is the main application market of nano ATO powder. Nano-composite transparent antistatic coatings can be prepared by adding nano-ATO powder as a conductive filler to the matrix resin (such as polyamide and acrylic) and selecting an appropriate dispersion method. Since the previous conductive fillers usually use carbon black, they are inferior to ATO powder in color control.

How is Antimony Tin Oxide ATO Powder produced?
Tin antimony oxide is a mixture in which the oxides of Sb and Sn coexist in different proportions. In common antimony tin oxide mixtures, the ratio of Sb and Sn oxides is roughly 1:1, and there are some mixtures with ratios of 2:1 or 3:1. The following are some common production methods of antimony tin oxide:

Chloride oxidation method:
Chloride oxidation is a commonly used method for preparing antimony tin oxide. The method is to heat antimony and tin chloride together with an appropriate amount of oxidant to get a mixture of antimony tin oxide. The disadvantage of this method is that it will produce toxic gases such as chlorine gas and require environmental protection measures.

Metal oxide eutectic method:
The metal oxide eutectic method is to heat and melt the metal oxides of antimony and tin with appropriate additives to obtain a mixture of antimony tin oxide. The advantages of this method are simple process and low cost, but the purity of the product is low.

Carbothermal reduction method:
The carbothermic reduction method reduces antimony oxide and tin oxide to a mixture of antimony tin oxide by using carbon as a reducing agent at high temperatures. The advantage of this method is that it can prepare high-purity antimony tin oxide, but the process is more complicated and requires high-temperature equipment.

Precipitation method:
The precipitation method is to add an appropriate amount of precipitating agent to the solution containing Sb and Sn ions so that Sb and Sn ions form a residue, then filter, wash, and dry the residue to obtain a mixture of antimony tin oxide. The advantages of this method are high product purity and a simple process, but it needs to be washed and dried several times.

Applications of Antimony Tin Oxide ATO Powder:

Adding nano-level ATO powder directly during fiber spinning, the key is the compatibility of inorganic nano-level ATO with fiber materials, and special dispersing additives need to be added;

Add nano-level ATO or textile auxiliaries in the dyeing process of raw materials (such as wool tops and polyester yarns) to complete dyeing and functionalization in one step;

Add nano-level ATO textile auxiliaries during the dyeing or finishing of grey fabrics.

Nano ATO powder has a small particle size, has good compatibility with plastics, and has a light color, which broadens the application of conductive powders on plastics. Conductive ATO can be made into plastic additives, or plastic conductive masterbatch can be made into conductive plastic. If the ATO particles are large, they will negatively impact the production of conductive plastics. Therefore, ATO raw materials with the smallest possible particle size are required. Other applications of antimony tin oxide include:

1. Antimony tin oxide nanoparticles show excellent electrical and optical properties.

2. Antimony oxide can be used in optoelectronic and flat panel display devices, such as LED, LCD, and ECD.

3. Antimony oxide can also be used in solar cells and transparent electrodes.

4. The high conductivity of antimony oxide makes it suitable for use as an antistatic material in coatings, chemical fiber, and polymer film industries.

5. The antimony tin oxide nanoparticles also show high heat resistance.

6. Antimony oxide can shield the heat in buildings, glass, and hot mirrors.

7. Antimony oxide can also be used in automobile and aircraft glass to prevent fog and frost.

8. Antimony tin oxide nanoparticles have the characteristics of reducing microwaves.

9. Antimony oxide can be used in areas that must be shielded from electromagnetic waves. These areas include computer rooms and radars.

FAQs of Antimony Tin Oxide (ATO) Powder CAS 128221-48-7
Q: What is antimony tin oxide used for?
A: Antimony tin oxide (ATO) powder, identified by the CAS number 128221-48-7, finds extensive application across various industries due to its unique properties. In electronics, ATO is used as a transparent conductive material in displays, touch screens, and photovoltaic cells, where it provides high transparency combined with electrical conductivity. In coatings and paints, ATO imparts anti-static, UV-blocking, and heat reflective properties, making it ideal for protective coatings on vehicles, buildings, and electronic devices. Within the ceramics industry, ATO serves as an additive that enhances thermal stability and mechanical strength. It also has applications in the production of flame retardants and catalysts, contributing to improved safety and efficiency in manufacturing processes.

Q: Is antimony tin oxide toxic for humans?
A: The toxicity of antimony tin oxide is relatively low when handled properly. Studies suggest that exposure to antimony compounds can cause irritation of the upper respiratory tract, eyes, and skin upon direct contact or inhalation of dust particles. However, when used within recommended concentration limits and following good manufacturing practices, the risk of adverse health effects is minimized. Personal protective equipment (PPE) such as gloves, safety glasses, and respiratory protection should be utilized during handling to ensure safe usage. For specific applications, especially those involving prolonged skin contact or ingestion, consulting relevant safety data sheets and regulatory guidelines is advisable.

Q: What is the formula of antimony tin oxide?
A: Antimony tin oxide (ATO) typically has the general formula Sb₂O₃·SnO₂, although the exact stoichiometry may vary depending on the synthesis method and intended application. This compound consists of antimony atoms (Sb) and tin atoms (Sn), both of which are oxidized, forming a mixed metal oxide. The arrangement of these atoms results in a material that exhibits excellent electrical conductivity while maintaining optical transparency, which is crucial for applications in transparent conductive films and coatings. Depending on the ratio of antimony to tin, the properties of ATO can be tailored to meet specific requirements, allowing for customization of conductivity, transparency, and other physical characteristics.

Q: Is antimony tin oxide safe in skincare?
A: Antimony tin oxide is not commonly used in skincare products due to its primary applications in electronics and coatings. However, if incorporated into cosmetic formulations, it would need to adhere strictly to safety guidelines and concentration limits set by regulatory bodies. While there is limited information available on its use in cosmetics, ATO is generally considered non-toxic under proper conditions. Manufacturers must follow good manufacturing practices to ensure that any potential risks are mitigated. Importantly, before including ATO in skincare products, thorough testing should be conducted to confirm its safety for topical use, considering factors like irritation and sensitization potential.
