Ikintu nyamukuru kigize talc ni hydrotalcite hydrous magnesium silikatike hamwe na formula ya molekuline ya mg3 [si4o10] (OH) 2. Talc ni sisitemu ya monoclinic.Kirisiti ni pseudohexagonal cyangwa rombic, rimwe na rimwe.Mubisanzwe ni binini cyane, bifite amababi, radiyo na fibrous.Ntabwo ifite ibara kandi ibonerana cyangwa yera, ariko ni icyatsi kibisi, umuhondo werurutse, umutuku wijimye cyangwa umutuku wijimye bitewe numwanda muto;ubuso bwa clavage ni isaro nziza.Gukomera 1, uburemere bwihariye 2.7-2.8.

Ifu ya Talc ifite imiterere myiza yumubiri nubumashini nka lubricité, anti-fire, anti-acide, insulation, aho gushonga cyane, kudakora imiti, imbaraga zitwikiriye neza, ubworoherane, urumuri rwiza, adsorption ikomeye, nibindi kuko imiterere ya kristu ya talc itondekanye, ifite imyumvire yo kugabana byoroshye mumunzani no gusiga bidasanzwe.Niba ibikubiye muri Fe2O3 ari byinshi cyane, insulasiyo yayo izagabanuka.
