Sericite
ʻO Sericite kahi ʻano hou o ka mineral ʻoihana me kahi ʻano papa, ʻo ia ka subspecies o muscovite i loko o ka ʻohana mika me nā unahi maikaʻi loa.ʻO ka mānoanoa he 2.78-2.88g / cm 3, ʻo ka paʻakikī he 2-2.5, a ʻo ke anawaena-mānoanoa lākiō he> 50. Hiki ke hoʻokaʻawale ʻia i loko o nā flakes lahilahi loa, me ka luster siliki a me ka manaʻo maʻalahi, piha i ka elasticity, hiki ke maʻalahi, kaʻakika a me ka alkali kū'ē, ikaika uila insulation, wela ke kū'ē (a hiki i 600 o C), a me ka haʻahaʻa coefficient o thermal hoʻonui, a ʻO ka ili he ikaika UV kū'ē, maikaʻi abrasion kū'ē a me ka lole pale.ʻO ka modulus elastic he 1505-2134MPa, ʻo ka ikaika tensile he 170-360MPa, ʻo ka ikaika shear he 215-302MPa, a ʻo ka conductivity thermal he 0.419-0.670W.(MK) -1 .ʻO ka mea nui he potassium silicate aluminosilicate mineral, he kālā keʻokeʻo a i ʻole keʻokeʻo hina, ma ke ʻano o nā unahi maikaʻi.ʻO kona molecular formula (H 2 KAl 3 (SiC4) 3. Themineral composition is relative simple and the content of toxic elements is very low , ʻAʻohe mea radioactive, hiki ke hoʻohana ʻia e like me nā mea ʻōmaʻomaʻo.
