ʻO ka pauka Talc kahi huahana ʻoihana.He magnesium silicate mineral talc hui talc.ʻO ka mea nui he magnesium silicate wai.Ma hope o ka ʻoki ʻana, mālama ʻia me ka waika hydrochloric, holoi ʻia me ka wai a maloʻo.
Loaʻa i ka Talc pauka nā waiwai kino a me nā mea kemika e like me ka lubricity, ke pale ahi, ka pale ʻana i ka waikawa, ka insulation, ka helu 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 hoʻopiha ʻana i nā huahana plastik a me nā pepa, ka hoʻopiha piha a me ka anti adhesion agent o nā huahana rubber, ka pena kiʻekiʻe, etc.

Loaʻa i ka Talc nā waiwai kino a me nā kemika maikaʻi e like me ka lubricity, anti adhesion, kōkua kahe, pale ahi, pale ʻana i ka waikawa, insulation, kiʻekiʻe heheʻe kiʻekiʻe, nā mea kemika hana ʻole, mana uhi maikaʻi, palupalu, luster maikaʻi, a me ka adsorption ikaika.Ma muli o kona ʻano ʻano aniani i hoʻopaʻa ʻia, ua maʻalahi ka maʻalahi o ka talc i nā unahi a me ka lubricity kūikawā.Inā kiʻekiʻe ka maʻiʻo o Fe2O3, e hoʻemi ia i kona insulation.
