Introduction of silica sand :
Silica Sand (with Silica Powder), also known as Quartz Sand.It is a hard, wearresistant, chemical stability of minerals, the main mineral component is quartz, the main chemical ingredient is SiO2, the color of the powder is white or colorless.
Feature of silica sand :
1.High refractoriness
2.Low coefficient of thermal expansion
3.Low gas evolution and high permeability
4. Low bulk density
5.Artificial foundry sand
6.Low cleavage breakage rate
