Fused Silica Powder

MEIXING Series Fused Silica is made of highest purity Chinese crystal Silica by electrically fusing (fusing temperature 1800-2000)to amorophos Silicon dioxide , then specially engineered ingots, granular and flour form designed for different usage. This product has a very low thermal conductivity and excellent thermal shock resistance.

Special Features:
Near zero thermal expansion coefficient
Excellent thermal shock resistance
Pure(high SiO2 content,low Iron, Potassium & Sodium Oxide)
Consistent Chemistry
Statistically controlled particle size distribution

Main Applications:
EMC (Epoxy Molding Compound)
Investment Casting ,shell mould product
Refractory & Ceramic materials
Paint
Others
