Sericite
Sericite ni ubwoko bushya bwamabuye y'agaciro afite imiterere itandukanye, akaba ari ubwoko bwa muscovite mumuryango wa mika ufite umunzani mwiza cyane.Ubucucike ni 2.78-2.88g / cm 3, ubukana ni 2-2.5, naho igipimo cya diameter-umubyimba ni> 50. Irashobora kugabanywamo uduce duto cyane, hamwe na silike irabagirana kandi ikumva neza, yuzuye ibintu byoroshye, byoroshye, acide na alkali irwanya, amashanyarazi akomeye, irwanya ubushyuhe (kugeza kuri 600 o C), hamwe na coefficient nkeya yo kwagura ubushyuhe, kandi Ubuso bufite imbaraga zikomeye za UV, kurwanya abrasion nziza no kwambara.Modulus ya elastique ni 1505-2134MPa, imbaraga zingana ni 170-360MPa, imbaraga zo gukata ni 215-302MPa, naho ubushyuhe bwumuriro ni 0.419-0.670W.(MK) -1.Ibyingenzi byingenzi ni potasiyumu silikate ya aluminiyose yumutuku, ikaba ifeza-yera cyangwa imvi-yera, muburyo bwiminzani.Inzira ya molekuline ni (H 2 KAl 3 (SiC4) 3. Ibigize insinale biroroshye cyane kandi nibirimo ibintu byuburozi biri hasi cyane, Nta bintu bikora radio, bishobora gukoreshwa nkibikoresho byatsi.
