Titanium dioxide is an important chemical substance widely used in many fields.
1. The properties of titanium dioxide
Titanium dioxide is a white solid powder with the chemical formula TiO2. It has high light reflectivity and chemical stability and is widely used in various fields. The molecular structure of titanium dioxide is divided into rutile and rutile types. The rutile type has high light reflectivity and photocatalytic activity, while the rutile type has good thermal and chemical stability.
2. Preparation of titanium dioxide
The preparation methods of titanium dioxide mainly include gas-phase, liquid-phase, and solid-phase methods. Among them, the gas-phase method is the most commonly used preparation method, which generates titanium dioxide by reacting titanium powder with oxygen at high temperatures. The liquid phase rule is to prepare titanium dioxide from titanium salt solution by hydrolysis, precipitation or sol-gel. The solid-phase rule is to mix titanium powder with an oxidant and heat it to generate titanium dioxide.
3. The application of titanium dioxide
In the field of coatings,
Titanium dioxide is widely used in coatings due to its high reflectivity and chemical stability. It can be used as a white pigment to improve coatings' covering power and weather resistance. Meanwhile, titanium dioxide also has a photocatalytic effect, which can degrade organic matter and eliminate odors.
Cosmetics field
Titanium dioxide has also been widely used in the field of cosmetics. It can be used as a pigment and covering agent to improve cosmetics' covering power and durability. Meanwhile, titanium dioxide can also serve as a sunscreen, effectively preventing UV damage to the skin.
Catalyst field
Titanium dioxide also has extensive applications in the field of catalysts. It can serve as a photocatalyst, utilizing light energy to catalyze the decomposition of organic compounds and eliminate odors. Meanwhile, titanium dioxide can also serve as a catalyst carrier to enhance the activity and selectivity of the catalyst.
The role of titanium dioxide in the industrial field is pervasive. In addition to the fields mentioned above of coatings, cosmetics, catalysts, etc., it also has the following functions:
Plastic industry: Titanium dioxide can be used as a white pigment for plastics, increasing their durability and UV resistance. Various white or semi-transparent products, such as household appliances, medical devices, etc., can be manufactured by adding titanium dioxide.
Paper and textile industry:
In the paper and textile industry, adding titanium dioxide can make the paper smoother and have a higher whiteness. For textiles, titanium dioxide can provide UV resistance and increase their durability.
Food industry: Titanium dioxide is used as an additive due to its high whiteness and non-toxic properties; it is mainly used in cheese, candy, biscuits and other products to improve the appearance and taste of food.
Refractory glass, glaze, enamel, clay, high-temperature resistant experimental vessels, etc.: Titanium dioxide has a high melting point and is also used to manufacture refractory glass, glaze, enamel, clay, high-temperature resistant experimental vessels, etc.
Other fields
In addition to the abovementioned fields, titanium dioxide is widely used in ceramics, glass, electronics and other fields. For example, in the field of ceramics, titanium dioxide can improve the weather resistance and wear resistance of ceramic material; In the fields of glass, titanium dioxide can improve the transparency and weather resistance of glass; In the field of electronics, titanium dioxide can be used as a raw material for electrode materials and electronic components.
