Igice cy'ingenzi cya talc ni hydrotalcite hydrous magnesium silicate ifite formula ya molekile ya mg3 [si4o10] (OH) 2. Talc ibarizwa muri sisitemu ya monoclinic. Kristale iba pseudohexagonal cyangwa rhombic, rimwe na rimwe. Akenshi iba ifite ibice byinshi bikomeye, bifite amababi, radial na fibrous aggregates. Nta ibara kandi irabagirana cyangwa umweru, ariko iba icyatsi kibisi cyoroshye, umuhondo woroshye, umukara woroshye cyangwa umutuku woroshye bitewe n'umwanda muto; ubuso bw'aho butandukaniye ni ubwiza bw'amasaro. Ubukomere bwa 1, uburemere bwihariye 2.7-2.8.

Ifu ya Talc ifite imiterere myiza cyane ya fiziki n'iya shimi nko gushonga, kurwanya umuriro, kurwanya aside, gushyushya, gushonga cyane, kudakora kwa shimi, imbaraga nziza zo gutwikira, ubworoherane, ubwiza bwiza, gushongesha cyane, nibindi. Kubera ko imiterere ya kristalo ya Talc igizwe n'ibice bitandukanye, ifite imiterere yoroshye yo gucikamo ibice n'ubwiza bwihariye. Iyo ingano ya Fe2O3 ari nyinshi cyane, gushonga kwayo kuzagabanuka.

Imikoreshereze ya talc:

(1) Igipimo cy'ubwiza (Hz): gikoreshwa mu bwoko bwose bw'ifu ihumura, ifu y'ubwiza, ifu ya talcum, n'ibindi.

(2) Ubwoko bw'ibiribwa by'imiti (YS): ikinini cy'imiti, isukari itwikiriye, ifu y'ubushyuhe ishyushye, imiti y'Abashinwa, inyongeramusaruro ku biribwa, ikintu gikingira indwara, n'ibindi.

(3) Igipimo cyo gusiga (TL): gikoreshwa mu gusiga irangi ry'umubiri wera n'ubwoko bwose bw'imyambaro ishingiye ku mazi, ishingiye ku mavuta, irangi ry'inganda, irangi ririnda, n'ibindi.

(4) Igipimo cy'impapuro (zz): gikoreshwa nk'icyuzuza ubwoko bwose bw'impapuro n'impapuro, ibikoresho byo kugenzura asphalt mu giti.

(5) Igipimo cya pulasitiki (SL): gikoreshwa nk'inyunganiramirire ya polipropiline, nylon, polivinyl chloride, poliyetinamu, polisitirene, poliyetinamu n'izindi pulasitiki.

(6) Icyiciro cya Rubber (AJ): gikoreshwa mu kuzuza rubber no kurwanya gufatana kw'ibicuruzwa bya rubber.
