High Purity Silica White Powder For Media Film

Feature

High purity silica white powder is commonly used as a media film in various industries such as electronics, optics, and 

pharmaceuticals. It is known for its excellent optical properties, high thermal stability, and low electrical conductivity.

Media film refers to a thin layer of material that is applied onto surfaces to enhance their performance or protect them from 

external factors. In the case of high purity silica white powder, it is often used as a coating material for optical lenses, display 

panels, and semiconductor devices.

The main characteristics of high purity silica white powder include:

1. High purity: The powder is manufactured with strict quality control measures to ensure a high level of purity, typically above 

99.9%. This purity level is crucial for applications where impurities can negatively impact the performance of the coated 

surfaces.

2. Excellent optical properties: Silica white powder has a high transparency in the visible light spectrum, allowing it to be used 

as a media film for optical devices such as lenses and prisms. It also has a low refractive index, which helps reduce reflection 

and improve light transmission.

3. High thermal stability: Silica white powder can withstand high temperatures without undergoing significant changes in its 

physical or chemical properties. This makes it suitable for applications where the coated surfaces are exposed to elevated 

temperatures, such as in the manufacturing of electronic components.

4. Low electrical conductivity: The powder has a low electrical conductivity, which is essential for preventing electrical interference 

or short circuits in electronic devices. This property makes it an ideal material for coating semiconductor devices and other electronic

components.

Overall, high purity silica white powder is a versatile material that finds applications in various industries due to its excellent 

optical properties, high thermal stability, and low electrical conductivity. Its use as a media film helps enhance the performance 

and durability of coated surfaces in electronics, optics, and pharmaceutical applications.
