Chrysotile chemical structure
WebChrysotile is a sheet silicate which is formed as a very thin rolled sheet. The sheet is about 8 angstoms thick (0.8 nanometers thick). It is composed of a sandwich of magnesium and silica. In the lung, the acid environment of the macrophage scavenger cell quickly breaks apart the sheet structure causing the fiber to decompose into small pieces.
