69012-64-2 Usage

Chemical Properties

Amorphous silica, the noncrystalline form of SiO2, is a transparent to gray, odorless, amorphous powder

Uses

None; produced only as a by-product.

Health Hazard

Amorphous silica fume exposure is associated with recurrent fever, similar to metal fume fever, and nonprogressive pulmonary changes.More recently, the importance of silica fume particle size on toxicity has been noted.8 Specifically, particles of the ultrafine size range may be expected to have higher toxicity compared with particles of larger size.

Safety Profile

An inhalation hazard. Much less toxic than crystalline forms. Does not cause silicosis. See also other silica entries

Incompatibilities

Silica, amorphous is a noncombustible solid. Generally unreactive chemically. Incompatible with fluorine, oxygen difluoride, chlorine trifluoride. Soluble in molten alkalis and reacts with most metallic oxides at high temperature.

Waste Disposal

Sanitary landfill.

Check Digit Verification of cas no

The CAS Registry Mumber 69012-64-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 6,9,0,1 and 2 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 69012-64:
(7*6)+(6*9)+(5*0)+(4*1)+(3*2)+(2*6)+(1*4)=122
122 % 10 = 2
So 69012-64-2 is a valid CAS Registry Number.
