Muscovite (White mica)
Mica muaj muscovite, Biotite, Phlogopite, lepidolite thiab lwm yam.Muscovite yog mica ntau tshaj plaws.
Mica muaj kev ua haujlwm siab rwb thaiv tsev, kub tsis kam, acid tsis kam, alkali corrosion kuj, thiab thermal expansion coefficient me me.Tsis muaj teeb meem li cas nws tawg, nws yog nyob rau hauv daim ntawv ntawm flakes, nrog zoo elasticity thiab toughness.Mica hmoov muaj ib txoj kab uas hla loj-rau-thickness piv, zoo zawv zawg zog, muaj zog npog kev ua tau zoo thiab muaj zog adhesion.
Mica hmoov yog dav siv nyob rau hauv lub tshav pob ntawm rwb thaiv tsev, tshav kub rwb thaiv tsev, xim, coatings, pigments, tiv thaiv hluav taws, yas, roj hmab, ceramics, roj drilling, vuam electrodes, tshuaj pleev ib ce, aerospace, thiab lwm yam mica tshuaj muaj pes tsawg leeg.

Sericite
Sericite yog ib hom tshiab ntawm cov ntxhia hauv kev lag luam nrog cov txheej txheem txheej, uas yog cov subspecies ntawm muscovite hauv tsev neeg mica nrog cov nplai zoo heev.Qhov ceev yog 2.78-2.88g / cm 3, hardness yog 2-2.5, thiab txoj kab uas hla-thickness ratio yog> 50. Nws yuav muab faib ua nyias nyias flakes, nrog silk luster thiab du zoo nkaus li, tag nrho ntawm elasticity, yooj, acid thiab alkali tsis kam, muaj zog hluav taws xob rwb thaiv tsev, kub tsis kam (txog 600 o C), thiab qis coefficient ntawm thermal expansion, thiab nto muaj zog UV tsis kam, zoo abrasion tsis kam thiab hnav tsis kam.Lub elastic modulus yog 1505-2134MPa, lub zog tensile yog 170-360MPa, lub zog shear yog 215-302MPa, thiab thermal conductivity yog 0.419-0.670W.(MK) -1.Lub ntsiab tivthaiv yog ib tug poov tshuaj silicate aluminosilicate ntxhia, uas yog silver-dawb los yog greyish-dawb, nyob rau hauv daim ntawv ntawm nplua nplai.Nws cov mis molecular yog (H 2 KAl 3 (SiC4) 3. Themineral muaj pes tsawg leeg yog qhov yooj yim thiab cov ntsiab lus ntawm cov tshuaj lom neeg tsis tshua muaj siab, tsis muaj cov khoom siv hluav taws xob, tuaj yeem siv los ua cov ntaub ntawv ntsuab.
