Thermal decomposition of talc: A review

 · At higher temperatures silica crystallizes as cristobalite, whereas at 1473 K enstatite converts into the high-temperature crystal modification, protoenstatite. When studying the solubility of the decomposition products of talc in hydrochloric acid and sodium hydroxide solutions, Avgustinik et al. [20,21] showed that free magnesium oxide was formed in a …

Investigation of the thermal decomposition of talc: Ingenta Connect

The results showed that the decomposition of talc commenced at ∼800°C, peaking at ∼895°C, with the formation of enstatite and amorphous silica. An isothermal treatment at 1000°C caused the complete dehydroxylation of talc. The XRD and FTIR results indicated that the enstatite and amorphous silica phases were transformed into ...

Talc

Talc, or talcum, is a clay mineral, composed of hydrated magnesium silicate with the chemical formula Mg3Si4O10(OH)2. Talc in powdered form, often combined with corn starch, is used as baby powder.
