TALC Chemical Properties,Uses,Production
Chemical Properties
White, apple-green, gray powder; pearly or greasy luster, greasy feel. Mohs hardness 1–1.5 (may be harder when impure), high resistance to acids, alkalies, and heat.
Uses
Chiefly as a ceramic insulator in electronic devices.
Definition
A natural hydrous magnesium silicate. Compact, massive varieties may be called steatite in distinction from the foliated varieties, which are called talc. Soapstone is an impure variety of steatite.
Hazard
Toxic by inhalation. Effects pulmonary function and causes pulmonary fibrosis. Questionable carcinogen.
Health Hazard
The fibrous talc in soapstone dust causes fibrotic pneumoconiosis; an increased incidence of cancer of the lungs and pleura has been reported.
Industrial uses
Steatites are noted for their excellent electricalproperties and low cost. They are easily formedand fired at relatively low temperatures. However,compositions containing little or no clayor plastic material present fabricating problemsbecause of a narrow firing range. Steatite partsare vacuum-tight, can be readily bonded toother materials, and can be glazed or ground tohigh-quality surfaces.
