Features: ● Extremely low linear expansion coefficient and low internal stress ● The product has high purity, good whiteness and uniform particle size distribution; ● Good electromagnetic radiation ● Low ion content, low conductivity, excellent electrical insulation; ● Stable chemical properties and high humidity resistance; ● Acid and alkali resistance, high temperature resistance, good insulation performance.
Fused silicon powder (Fused silica) is a silicon powder made of natural high-quality quartz, smelted at high temperature, cooled amorphous silica as the main raw material, and then processed by a unique process. The product has high purity, low thermal expansion coefficient, low internal stress, high moisture resistance, low radioactivity and other excellent characteristics. And as a plastic sealing material for closed integrated circuits, it has outstanding advantages such as good dynamics, less overflow, and large filling amount.
Scope of Application:
Fused silicon powder has a wide range of applications, mainly used in electronic packaging, investment casting, high-grade electrical insulation, paint coatings, silicone rubber, refractory materials, high-grade plastics, special ceramics and other industries.
