Talc powder ke sehlahisoa sa indasteri.Ke magnesium silicate mineral talc group talc.Karolo e ka sehloohong ke silicate ea magnesium e nang le metsi.Ka mor'a ho senya, e phekoloa ka hydrochloric acid, e hlatsuoa ka metsi le ho omisoa.
Talc phofo e na le lisebelisoa tse ntle tsa 'mele le lik'hemik'hale tse kang lubricity, fire resistance, acid resistance, insulation, high melting point, lik'hemik'hale tse sa sebetseng, matla a ho koahela, bonolo, khanya e ntle le adsorption e matla.
Talc phofo hangata e sebelisoa e le ho tlatsa lihlahisoa tsa polasetiki le tsa pampiri, filler ea rabara le anti adhesion agent ea lihlahisoa tsa rabara, pente ea boemo bo holimo, jj.

Talc e na le lisebelisoa tse ntle tsa 'mele le tsa lik'hemik'hale tse kang lubricity, anti adhesion, flow aid, fire resistance, acid resistance, insulation, high melting point, inactive chemical properties, good covering power, softness, good luster, le adsorption e matla.Ka lebaka la sebopeho sa eona sa kristale, talc e na le tšekamelo ea ho aroha habonolo ka sekala le lubricity e khethehileng.Haeba litaba tsa Fe2O3 li phahame, li tla fokotsa ho kenngoa ha eona.
