Chinhu chikuru chetalc ndeye hydrotalcite hydrous magnesium silicate ine molecular formula ye mg3 [si4o10] (OH) 2. Talc ndeye monoclinic system.Iyo crystal ndeye pseudohexagonal kana rhombic, dzimwe nguva.Anowanzo kukora hombe, mashizha, radial uye fibrous aggregates.Haina ruvara uye yakajeka kana kuti chena, asi ine chiedza chegirini, chiedza chero, chitsvuku kana kunyange chitsvuku nekuda kwehuwandu husina kuchena;iyo cleavage surface is pearl luster.Kuoma 1, chaiyo giravhiti 2.7-2.8.

Talc poda ine yakanakisa yemuviri uye makemikari zvimiro zvakaita semafuta, kupikisa moto, asidi kuramba, kumisa, kunyungudika kwakakwira, kusaita kemikari, simba rekuvhara rakanaka, kupfava, kupenya kwakanaka, kushambadza kwakasimba, nezvimwe nekuti chimiro chekristaro chetalc chakaturikidzana, ine katsika kekutsemuka zviri nyore kuita zvikero uye kunyorova kwakakosha.Kana zvinyorwa zveFe2O3 zvakanyanyisa, kuvharidzira kwayo kuchaderedzwa.
