The idealized chemical formula of chrysotile is Mg3(Si2O5)(OH)4, although some of the magnesium ions may be replaced by iron or other cations. Substitution of the hydroxide ions for fluoride, oxide or chloride is also known, but rarer. A related, but much rarer, mineral is pecoraite, in which all the magnesium cations of chrysotile are substituted by nickel cations. Chrysotile is resistant to even strong bases (asbestos is thus stable in high pH pore water of Po… WebChrysotile has the following percent composition: 28.03% Mg, 21.60% Si, 1.16% H, and 49.21% O.
