Eyona nto iphambili kwi-talc yi-hydrotalcite hydrous magnesium silicate enefomula yemolekyuli ye-mg3 [si4o10] (OH) 2. I-Talc yeyenkqubo ye-monoclinic. I-crystal i-pseudohexagonal okanye i-rhombic, ngamanye amaxesha. Ihlala ixinene kakhulu, inamagqabi, ine-radial kwaye ine-fibrous aggregates. Ayinambala kwaye icacile okanye imhlophe, kodwa iluhlaza okotshani, ityheli okotshani, imdaka okotshani okanye ibomvu okotshani ngenxa yobuninzi obuncinci bokungcola; umphezulu wokuqhekeka ulukhazimla lweperile. Ubulukhuni 1, ubunzima obuthile 2.7-2.8.

Umgubo weTalc uneempawu ezintle kakhulu zomzimba nezekhemikhali ezifana nokuthambisa, ukumelana nomlilo, ukumelana ne-asidi, ukugquma, indawo yokunyibilika ephezulu, ukungasebenzi kweekhemikhali, amandla okugquma alungileyo, ukuthamba, ukukhanya okuhle, ukufunxa okunamandla, njl. kuba ulwakhiwo lwekristale lweTalc luneengqimba, lunomkhuba wokuqhekeka lula lube zizikali kunye nokuthambisa okukhethekileyo. Ukuba umxholo weFe2O3 uphezulu kakhulu, ukugquma kwayo kuya kuncipha.

Ukusetyenziswa kwe-talc:

(1) Udidi lweZithambiso (Hz): lusetyenziselwa zonke iintlobo zepowder yokufumisa, ipowder yobuhle, ipowder ye-talcum, njl.

(2) Uhlobo lokutya kwamayeza (YS): ithebhulethi yamayeza, iswekile, umgubo wobushushu obukhali, ummiselo wamayeza aseTshayina, isongezo sokutya, iarhente yokwahlulahlula, njl.njl.

(3) Udidi lokugquma (TL): lusetyenziselwa umbala omhlophe womzimba kunye nazo zonke iintlobo zokugquma okusekwe emanzini, okusekwe kwioyile, okusekwe kwi-resin kwimizi-mveliso, i-primer, ipeyinti yokukhusela, njl.njl.

(4) Udidi lwephepha (zz): lusetyenziswa njengesizalisi sazo zonke iintlobo zephepha kunye nebhodi yephepha, iarhente yokulawula i-asphalt yomthi.

(5) Uhlobo lweplastiki (SL): lusetyenziswa njengesizalisi se-polypropylene, i-nylon, i-polyvinyl chloride, i-polyethylene, i-polystyrene, i-polyester kunye nezinye iiplastiki.

(6) Uhlobo lwerabha (AJ): isetyenziselwa ukugcwalisa irabha kunye nearhente yokulwa nokunamathela kwiimveliso zerabha.
