Silica Sand (with Silica Powder), also known as Quartz Sand.

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
