More info

Fused Silica Powder is produced from high-purity natural quartz sand, which is electrically fused at high temperatures and rapidly cooled to form an amorphous silica glass. Then it will be processed through precise crushing, grinding, and classification technologies to achieve a well-defined particle size distribution. It is characterized by exceptional chemical purity and thermal stability, with its unique amorphous structure granting a very low coefficient of thermal expansion (CTE) and superior electrical insulation properties. Available in a wide range of purities and particle sizes, HM's Silica Powder meets the highest standards of quality and reliability for demanding applications.
