The Composition and Color of Garnet Sand
Garnet sand is a natural mineral ore,called natural emery sand.
It has similar characteristics with man-made emery sand( white fused alumina,brown fused alumina,black silicon carbide and green silicon carbide),also has differences.
Today we talk about compostion and color of our garnet sand:
Firstly, Mineral composition of garnet sand
Almandine Ganet ——————- 98.5%
Ilmenite——————————1.42%
Others———————————0.08%
Secondly,chemical composition of garnet sand
SiO2————————————34-40%
Al2O3———————————-17-21%
FeO+Fe2O3—————————25-31%
MnO———————————–0-1%
CaO————————————5-20%
MgO————————————5-6%
About color of garnet sand,in China market,also can say in our factory,there are 4kinds: red,pink,brown and green.
Red,brown and green are all from mountain,but pink is from river.
Red and pink is widely used in the market,brown one sometimes are used to instead of brown fused alumina,because they exactly look the same.
