Cov khoom tseem ceeb ntawm talc yog magnesium silicate uas muaj dej, nrog rau cov mis molecular Mg3 [Si4O10] (OH) 2. Talc koom nrog lub cev monoclinic. Cov siv lead ua yog nyob rau hauv daim ntawv ntawm pseudo hexagonal lossis rhombic flakes, qee zaum pom. Feem ntau tsim rau hauv cov clumps ntom, zoo li nplooj, radial, thiab fibrous aggregates. Tsis muaj xim pob tshab lossis dawb, tab sis tshwm sim lub teeb ntsuab, lub teeb daj, lub teeb xim av, lossis txawm tias lub teeb liab vim muaj me ntsis ntawm cov khoom tsis huv; Qhov chaw txiav qhia tau hais tias muaj lub teeb ci ntsa iab. Hardness 1, qhov hnyav tshwj xeeb 2.7-2.8.

Talc muaj cov khoom zoo heev rau lub cev thiab tshuaj xws li lubricity, anti adhesion, flow aid, fire resistance, acid resilient, melting point siab, inactive chemical functions, well sheet strength, softness, ci ntsa iab, thiab adsorption zoo. Vim nws cov qauv siv lead ua ke, talc yooj yim faib ua nplai thiab lubricity tshwj xeeb. Yog tias Fe2O3 muaj ntau, nws yuav txo nws cov rwb thaiv tsev.

Talc yog mos, nrog Mohs hardness coefficient ntawm 1-1.5 thiab qhov kev xav swb. Qhov {001} cleavage yog tiav heev, thiab nws yooj yim tawg ua tej daim nyias nyias. Lub kaum sab xis ntuj so yog me me (35 ° ~ 40 °), thiab nws tsis ruaj khov heev. Lub pob zeb nyob ib puag ncig yog silicified thiab nplua magnesite, magnesite, lean ore, lossis dolomite marble. Tsuas yog ob peb lub pob zeb ruaj khov nruab nrab, lawv feem ntau tsis ruaj khov, nrog cov pob qij txha thiab tawg. Cov khoom siv lub cev thiab cov khoom siv kho tshuab ntawm cov ore thiab cov pob zeb nyob ib puag ncig muaj kev cuam tshuam loj heev rau cov txheej txheem mining.
