Silica, amorphous (diatomaceous earth, precipitated and gel silica) Possesses little or no potential to oause silicosis. Most sources of amorphous silica contain quartz (see orystalline silica, below). If greater than 1% quartz is present, the quartz hazard must be addressed. When strongly heated (calcined) with limestone, diatomaceous earth becomes crystalline and can cause silicosis. Amorphous silica has been associated with lung fibrosis, but the role of crystalline silica contamination remains controversial. 10 mg/m (precipitated silica, diatomaceous earth, silica gel) 3 mg/m (respirable dusH 2 mg/m (silica fume) 3000 mg/m White to gray powders. Odorless with a negligible vapor pressure. The TLV for dusts is 10 mg/m if no asbestos and less than 1% quartz ate present. [Pg.612]

A crystalline form of free silica, extremely hard and inert chemically very resistant to heat. Quartz in refractory bricks and amorphous silica in diatomaceous earth are altered to cristobalite when exposed to high temperatures (calcined). Cristobalite is extensively used in precision casting by the hot wax process, dental laboratory work, and certain speciality ceramics. [Pg.79]

Amorphous free silica (Noncrystalline) Diatomaceous earth A soft, gritty amorphous silica composed of minute siliceous skeletons of small aquatic plants. Used in filtration and decoloration of liquids, insulation, filler in dynamite, wax, textiles, plastics, paint, and rubber. Calcined and flux-calcined diatomaceous earth contains appreciable amounts of cristobalite, and dust levels should be the same as for cristobalite. [Pg.52]

The 2003 ACGIH proposed threshold limit value-time-weighted average (TLV-TWA) for amorphous silica, natural diatomaceous earth, is lOmg/m for the inhalable particulate and 3mg/m for respirable dust containing no asbestos and <1% quartz. [Pg.626]

Amorphous silica lacks a definite shape and an orderly atomic latticework. Types of amorphous silica include glass, vitreous glass fiber, large flocculated silica gel, diatomaceous earth, and opaline phase-fused silica in granular and powder form. These products provide high purity, reinforcement, great surface area, flatting properties, and thixotropy. Fused silica has an extremely low coefficient of linear thermal expansion and has become quite popular, especially in electronics applications. The amorphous silicas are compatible with thermosets, thermoplastics, silicone rubber, and other elastomers. [Pg.507]
