Amorphous silica, the noncrystalline form of SiO2, is a transparent to gray, odorless, amorphous powder white crystals or powder
Silicon dioxide occurs almost everywhere on earth. It is one of the most important and abundant oxides on earth, constituting about 60% weight of the earth’s crust as silica itself or in combination with other metal oxides in silicates. It commonly is found as sand in the vast ocean and river shores, their beds, deserts, rocks, and minerals.Silicon dioxide exists in several structural forms: polymorphic crystalline silica, synthetic quartz crystals, amorphous silica, and vitreous silica. This classification is not complete as there are other forms of silica synthesized for specialized applications.
Silica is an inert, naturally occurring mineral used as a carrier in some pesticide products and is sometimes used as an insecticide to control crawling insects, acting via its abrasive and desiccant properties. It is moderately soluble in water and stable in the environment. It is generally considered non-toxic to biodiversity and humans. However, there are some concerns that exposure to crystalline silica particles that are small enough to reach the lungs can cause lung cancer.

Characteristics-
PSA:
34.14000
Physical Properties:Colorless amorphous (i.e., fused silica) or crystalline (i.e., quartz) material having a low thermal expansion coefficient and excellent optical transmittance in far UV. Silica is insoluble in strong mineral acids and alkalis except HF, concentrated H3PO4, NH4HF2, concentrated alkali metal hydroxides. Owing to its good corrosion resistance to liquid metals such as Si, Ge, Sn, Pb, Ga, In, Tl, Rb, Bi, and Cd, it is used as crucible container for melting these metals, while silica is readily attacked in an inert atmosphere by molten metals such as Li, Na, K Mg, and Al. Quartz crystals are piezoelectric and pyroelectric. Maximum service temperature 1090°C.
