Talc, or talcum, is a clay mineral composed of hydrated magnesium silicate, with the chemical formula Mg 3 Si 4 O 10 (OH) 2. Talc in powdered form, often combined with corn starch, is used as baby powder. This mineral is used as a thickening agent and lubricant. It is an ingredient in ceramics, paints, and roofing material.

Talc is a hydrous magnesium silicate mineral with a chemical composition of Mg 3 Si 4 O 10 (OH) 2. Although the composition of talc usually stays close to this generalized formula, some substitution occurs.

2023年8月25日 · Talc’s chemical formula is Mg3Si4O10(OH)2, which represents its basic composition of magnesium, silicon, and oxygen atoms arranged in sheets or layers. These layers are weakly bonded, giving talc its characteristic softness and easy cleavage into thin sheets.

2025年2月8日 · Talc, common silicate mineral that is distinguished from almost all other minerals by its extreme softness. Its soapy or greasy feel accounts for the name soapstone given to compact aggregates of talc and other rock-forming minerals. Dense aggregates of high-purity talc are called steatite.

Several types of talc deposits may be distinguished according to the present composition and parent rock from which they are derived: The talc is formed by the alteration of sedimentary magnesium carbonate rocks (dolomite and magnesite) at elevated temperature and pressure.

Talc is a phyllosilicate mineral composed of hydrated magnesium silicate with the chemical formula Mg 3 Si 4 O 10 (OH) 2

Talc mineral or talcum powder is one of the most commonly found chemicals in our households. It is the primary constituent of the powder we apply on our faces to look fairer than usual. Scientifically speaking, talc is a clay mineral. We shall dwell more into the chemical composition aspect of talc in the latter part of this article.

ate. Pure talc has the formula Mg3Si4O10( H)2. It may contain variable amounts of associated minerals among which chlorites (hydrated aluminum and magnesium sili-cates), magnesite (magnesium carbonate), calcite (cal-cium carbonate), and dolomite (calcium and magnesium carbonate) are predomi.
