Introduction of silica sand :
Quartz sand is the quartz writing processing of silica particles. Also known as silica, quartz, quartz rock) is a texture hard, wearresisting, stable chemical properties of silicate minerals. In nature exist in quartz sandstone, quartzite and vein quartz. Quartz sandstone is consolidation of clastic rocks, quartz particles content more than 95%,From all kinds of magmatic rocks, sedimentary rocks and metamorphic rocks, heavy minerals is less, associated minerals as feldspar, mica and clay minerals content.Quartzite sedimentary origin and metamorphism, the boundaries of the former clastic particles and cement is not obvious, which is a deep metamorphic grade, quality, and the pure quartz ore.Vein quartz is formed by hydrothermal process, almost all is composed of quartz, dense block structure.
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

Advantage of silica sand :
1. High Usage Efficiency. The favor of the oil product is pure,
2. Low cost and widely applied.
3. Without heating and pressing the oil, save work, time and energy.
4.High grade products with competitive price;
5.Stable supply for reputable manufacture;
6.Low iron content and high purity;
Application of silica sand :
1.Silica sand is the main raw material of plate glass ,float glass ,optical glass.
2.Walling materials and finish material.
3.Silicate brick materials.
4.Producing sodium silicate.
5.Reinforce materials for organic compound.
6.Our silica sand can be used in metallurgy ,ceramic ,foundry and abrasives.
7.The silica sand also can be use in water treatment, sandblasting.
