He huahana ʻoihana ka pauka Talc. He hui talc mineral magnesium silicate ia. ʻO ka mea nui he magnesium silicate aqueous. Ma hope o ka kuʻi ʻana, mālama ʻia me ka waikawa hydrochloric, holoi ʻia me ka wai a hoʻomaloʻo ʻia.
Loaʻa i ka pauka Talc nā waiwai kino a me nā kemika maikaʻi loa e like me ka lubricity, ke kū'ē ʻana i ke ahi, ke kū'ē ʻana i ka waikawa, ka insulation, ke kiko heheʻe kiʻekiʻe, ka kemika hana ʻole, ka mana uhi maikaʻi, ka palupalu, ka luster maikaʻi a me ka adsorption ikaika.
Hoʻohana pinepine ʻia ka pauka Talc e like me ka mea hoʻopihapiha o nā huahana plastik a me ka pepa, ka mea hoʻopihapiha laholio a me ka mea hoʻopili anti-adhesion o nā huahana laholio, ka pena kiʻekiʻe, a pēlā aku.

Loaʻa i ka Talc nā waiwai kino a me nā kemika maikaʻi loa e like me ka lubricity, anti adhesion, flow aid, fire resistance, acid resistance, insulation, high helting point, inactivated chemical properties, good covering power, softness, good luster, and strong adsorption. Ma muli o kona ʻano kristal papa, he ʻano maʻalahi ka talc e māhelehele i nā unahi a me ka lubricity kūikawā. Inā kiʻekiʻe ka nui o Fe2O3, e hōʻemi ia i kona insulation.
