silica gel are used as a grease thickener, diluents for insecticide, and fillers for paint, rubber, and paper. Industrial byproducts of amorphous silica include fused silica and silica fume. Fumed amorphous silica, a fine white powder, is a byproduct of ferrosilicon, an electrometallurgical process.
crystalline silica dust. For any kind of dust, there are different particle sizes. When dust is inhaled, its point of deposition within the respiratory system is very much dependent upon the range of particle sizes present in the dust. It is the respirable (smallest particle size) fraction of crystalline silica dust which is of critical

Crystalline silica is a bigger worry for the health of our lungs. The most common form of crystalline silica is quartz, which is found in sand, gravel, clay, granite, diatomaceous earth, and many other forms of rock. Noncrystalline silica is found in glass, silicon carbide, and silicone. These materials are much less hazardous to the lungs.
