[product introduction]: fused silica powder is a kind of silicon powder made of natural high-grade quartz, high-temperature smelting, cooled amorphous silica as the main raw material, and then processed by a unique process. The product has high purity, low coefficient of thermal expansion, low internal stress, high moisture resistance and low radioactivity. As a plastic sealing material for closed integrated circuits, it has the outstanding advantages of good mobility, less overflow, large filling amount and so on.

[scope of application]: molten silicon powder is widely used in electronic packaging, investment casting, advanced electrical insulation, paint and coating, silicone rubber, refractory, advanced plastics, special ceramics and other industries.

[main features]:

1. Very low linear expansion coefficient and low internal stress

2. The product has high purity, good whiteness and uniform particle size distribution;

3. Good electromagnetic radiation

4. Low ion content, low conductivity, excellent electrical insulation;

5. Stable chemical properties and high moisture resistance;

6. Acid and alkali resistance, high temperature resistance and good insulation performance;
