Introduction of Hollow Silica Powder
Hollow silica powder is a special inorganic non-metallic material, whose main component is silicon dioxide (SiO₂). The characteristic of this powder is that the inside of its particles is a hollow structure, that is, hollow. Hollow silica powder has many unique properties, such as low density, high porosity, good thermal insulation performance, high specific surface area, etc. These characteristics make it have broad application prospects in many fields.

Application Areas of Hollow Silica Powder
Copper clad laminate
Added to epoxy resin, it can reduce the dielectric constant of PCB, increase signal transmission speed and reduce dielectric loss.
Photovoltaic glass
Used in the coating of photovoltaic glass, it can increase the stain resistance of the glass surface and increase the sunlight transmittance by 5%. The transmittance can be increased from 92% to 97%, greatly improving the light absorption efficiency of photovoltaic glass.
Catalytic and drug loading carrier
Due to its hollow structure, it can be used as a sustained-release agent in medicine. The hollow structure can be used as a drug storage chamber to release drugs at the appropriate location.

FAQs of Hollow Silica Powder
Q1: Where is silica stored hollow realization?
A1: Hollow silica particles, also known as mesoporous silica spheres (MSS) or hollow silica nanospheres (HSNS), are typically stored in airtight containers to prevent moisture absorption and contamination. They should be kept in a cool, dry place away from direct sunlight. For long-term storage, refrigeration may be beneficial to maintain stability.
Q2: Does hollow realization silica heal?
A2: Hollow silica structures do not have inherent healing properties in the traditional sense. However, hollow silica nanoparticles can be used in drug delivery systems where they can carry therapeutic agents to specific sites in the body, indirectly contributing to healing processes. Additionally, hollow silica nanoparticles can be functionalized with bioactive molecules that promote tissue regeneration or wound healing.
Q3: Are there any safety concerns with hollow silica powder?
A3: While hollow silica powder is generally considered safe, it is important to follow standard handling procedures to avoid inhalation, which can cause respiratory issues. Proper personal protective equipment (PPE) should be worn during handling, and the powder should be used in a well-ventilated area.
Q4: Can hollow silica powder be customized?
A4: Yes, hollow silica powder can be customized through surface modification techniques. This allows for the attachment of functional groups or the incorporation of specific molecules, tailoring the powder for particular applications.
