ʻO ka ʻāpana nui o ka talc he magnesium silicate i loaʻa ka wai, me ke ʻano molekala Mg3 [Si4O10] (OH) 2. No ka ʻōnaehana monoclinic ʻo Talc. Aia ke kristal ma ke ʻano o nā ʻāpana pseudo hexagonal a rhombic paha, i ʻike pinepine ʻia. Hoʻokumu pinepine ʻia i loko o nā puʻupuʻu mānoanoa, e like me ka lau, radial, a me nā fibrous aggregates. ʻAʻohe kala a ʻaʻohe keʻokeʻo paha, akā ʻike ʻia he ʻōmaʻomaʻo māmā, melemele māmā, ʻeleʻele māmā, a ʻulaʻula māmā paha ma muli o ke alo o kahi liʻiliʻi o nā haumia; Hōʻike ka ʻili cleavage i kahi luster momi. Paʻakikī 1, umekaumaha kikoʻī 2.7-2.8.

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.

He palupalu ka Talc, me kahi coefficient paʻakikī Mohs o 1-1.5 a me kahi manaʻo paheʻe. Ua piha loa ka ʻoki ʻana {001}, a he maʻalahi ke haki i nā ʻāpana lahilahi. He liʻiliʻi ke kihi hoʻomaha kūlohelohe (35 ° ~ 40 °), a he paʻa ʻole loa ia. ʻO ka pōhaku a puni he silicified a pahee magnesite, magnesite, ore lean, a i ʻole dolomite marble. Koe wale nō kekahi mau pōhaku paʻa iki, he paʻa ʻole lākou, me nā hono a me nā haki i hoʻomohala ʻia. ʻO nā waiwai kino a me nā mechanical o ka ore a me ka pōhaku a puni he hopena koʻikoʻi i ke kaʻina hana eli.

Papa kemika
Hoʻohana: Hoʻohana ʻia ma ke ʻano he mea hoʻoikaika a hoʻololi i nā ʻoihana kemika e like me ka laholio, nā plastics, ka pena, a pēlā aku. Nā Hiʻohiʻona: Hoʻonui i ke kūpaʻa o ke ʻano o ka huahana, hoʻonui i ka ikaika tensile, ka ikaika shear, ka ikaika wili, ka ikaika kaomi, hoʻemi i ka deformation, elongation, ka coefficient hoʻonui thermal, keʻokeʻo kiʻekiʻe, a me ka like ʻana o ka nui o ka ʻāpana a me ka hoʻopuehu ʻana.

Papa seramika
Hoʻohana: Hoʻohana ʻia no ka hana ʻana i nā keramika alapine kiʻekiʻe, nā keramika uea ʻole, nā keramika ʻoihana like ʻole, nā keramika kuhikuhipuʻuone, nā keramika o kēlā me kēia lā, a me nā glazes keramika. Nā Hiʻohiʻona: ʻAʻole hoʻololi ke kala o ka mahana kiʻekiʻe, hoʻonui ʻia ke keʻokeʻo ma hope o ka forging, ʻano like ka nui, maikaʻi ka luster, a me ka ʻili laumania.

Papa hoʻonani
Pahuhopu: He mea hoʻopihapiha kiʻekiʻe ia i ka ʻoihana hoʻonaninani. Nā Hiʻohiʻona: Loaʻa ka nui o ka element silicon. Loaʻa iā ia ka hana o ke ālai ʻana i nā kukuna infrared, no laila e hoʻonui ai i ka hana pale lā a me ka pale infrared o nā mea hoʻonaninani.

Papa lapaʻau a me ka papa meaʻai
Hoʻohana: Hoʻohana ʻia ma ke ʻano he mea hoʻohui i nā ʻoihana lāʻau lapaʻau a me nā meaʻai. Nā Hiʻohiʻona: ʻAʻohe mea ʻawahia, ʻaʻohe ala, me ke keʻokeʻo kiʻekiʻe, kūpono maikaʻi, ʻālohilohi ikaika, ʻono palupalu, a me ka laumania ikaika. ʻAʻole hoʻohaʻahaʻa ka waiwai pH o 7-9 i nā ʻano o ka huahana kumu.

Papa pepa
Kumu: Hoʻohana ʻia no nā huahana ʻoihana pepa kiʻekiʻe a haʻahaʻa. Nā ʻano: Loaʻa i ka pauka pepa nā ʻano o ke keʻokeʻo kiʻekiʻe, ka nui o nā ʻāpana paʻa, a me ka haʻahaʻa o ke komo ʻana. Hiki i ka pepa i hana ʻia me kēia pauka ke hoʻokō i ka laumania, ka ʻono, mālama i nā mea maka, a hoʻomaikaʻi i ke ola lawelawe o ka ʻupena resin.

Pauka Brucite
Hoʻohana: Hoʻohana ʻia no ka hana ʻana i ka porcelain uila, ka porcelain uila uea ʻole, nā ʻano keramika ʻoihana like ʻole, nā keramika kuhikuhipuʻuone, nā keramika o kēlā me kēia lā, a me ka glaze keramika. Nā Hiʻohiʻona: ʻAʻole e loli ke kala o ka mahana kiʻekiʻe, hoʻonui ʻia ke keʻokeʻo ma hope o ke kālai ʻia ʻana, ʻano like ka mānoanoa, maikaʻi ka ʻōlinolino, a me ka ʻili laumania.
