Kufotokozera mwachidule:

Sericite ndi mtundu watsopano wamafuta am'mafakitale okhala ndi mawonekedwe osanjikiza, omwe ndi mtundu wa muscovite wa banja la mica wokhala ndi masikelo abwino kwambiri.Kachulukidwe ndi 2.78-2.88g / cm 3, kuuma kwake ndi 2-2.5, ndi kukula kwake ndi> 50. Ikhoza kugawidwa kukhala ma flakes oonda kwambiri, ndi silika wonyezimira ndi kumverera kosalala, wodzaza ndi elasticity, kusinthasintha, asidi ndi kukana kwa alkali, kutsekemera kwamphamvu kwa magetsi, kukana kutentha (mpaka 600 o C), komanso kutsika kwapakati pakukula kwamafuta, ndipo Kumtunda kuli ndi kukana kwamphamvu kwa UV, kukana bwino kwa abrasion komanso kukana kuvala.Etastic modulus ndi 1505-2134MPa, mphamvu yokhazikika ndi 170-360MPa, kumeta ubweya wa ubweya ndi 215-302MPa, ndi matenthedwe matenthedwe ndi 0.419-0.670W.(MK) -1 .Chigawo chachikulu ndi potaziyamu silicate aluminosilicate mchere, womwe ndi siliva-woyera kapena imvi-woyera, mu mawonekedwe a mamba abwino.Mapangidwe ake a mamolekyu ndi (H 2 KAl 3 (SiC4) 3. Mapangidwe a Themineral ndi ophweka ndipo zomwe zili ndi poizoni ndizochepa kwambiri , Palibe ma radioactive element, omwe angagwiritsidwe ntchito ngati zipangizo zobiriwira.
