Impuphu ye-Talc iwumkhiqizo wezimboni. I-talc yeqembu le-talc ye-magnesium silicate. Ingxenye eyinhloko yi-magnesium silicate yamanzi. Ngemva kokuyichoboza, iphathwa nge-hydrochloric acid, igezwe ngamanzi bese yomiswa.
Impuphu ye-talc inezakhiwo ezinhle kakhulu zomzimba nezamakhemikhali njengokugcoba, ukumelana nomlilo, ukumelana ne-asidi, ukufudumala, iphuzu lokuncibilika eliphezulu, i-chemistry engasebenzi, amandla amahle okumboza, ubumnene, ukukhanya okuhle kanye nokumuncwa okunamandla.
Impuphu ye-talc ivame ukusetshenziswa njengokugcwalisa imikhiqizo yepulasitiki neyephepha, ukugcwalisa irabha kanye ne-anti-adhesive agent yemikhiqizo yerabha, upende wezinga eliphezulu, njll.

I-Talc inezakhiwo ezinhle kakhulu zomzimba nezamakhemikhali ezifana nokuthambisa, ukulwa nokunamathela, usizo lokugeleza, ukumelana nomlilo, ukumelana ne-asidi, ukufudumala, iphuzu lokuncibilika eliphezulu, izakhiwo zamakhemikhali ezingasebenzi, amandla amahle okumboza, ukuthamba, ukukhanya okuhle, kanye nokumuncwa okunamandla. Ngenxa yesakhiwo sayo sekristalu esinezingqimba, i-talc ithambekele ekuhlukaniseni kalula ibe yizikali kanye nokuthambisa okukhethekile. Uma okuqukethwe yi-Fe2O3 kuphezulu, kuzonciphisa ukufudumala kwayo.
