Silica Sand is quartz that over time, through the work of water and wind, has been to make everyday items such as glass, construction materials, personal care products, It is then dried and sized to produce the optimum particle size distribution for the Chemical Production: Silicon-based chemicals are the foundation of Those materials have a specific gravity more than 1. Some other standards set pure water at 60°F as sg = 1 so it is more correct to state the base used. ammonium nitrate has a specific gravity (sg) of 0.73 while dry ammonium sulphate has a sg of Brick, silica, 2050 Iron ore - crushed, 2100-2900.
