Sericite

tlhaloso e khuts'oane:

Sericite ke mofuta o mocha oa liminerale tsa indasteri tse nang le sebopeho se nang le lera, e leng mofuta o monyane oa muscovite lelapeng la mica le sekala se setle haholo.Boima ba 2.78-2.88g / cm 3, boima ke 2-2.5, 'me tekanyo ea bophara ba bophara ke> 50. E ka aroloa ka li-flakes tse tšesaane haholo, tse nang le silika e khanyang le maikutlo a boreleli, a tletseng elasticity, ho feto-fetoha ha maemo, ho hanyetsa acid le alkali, ho kenya motlakase ho matla, ho hanyetsa mocheso (ho fihlela ho 600 o C), le coefficient e tlase ea ho atolosoa ha mocheso, 'me Bokaholimo bo na le khanyetso e matla ea UV, ho hanyetsa hantle le ho roala.The elastic modulus ke 1505-2134MPa, matla a tensile ke 170-360MPa, matla a ho kuta ke 215-302MPa, 'me conductivity ea mocheso ke 0.419-0.670W.(MK) -1 .Karolo e ka sehloohong ke potassium silicate aluminosilicate mineral, e leng silevera-white kapa grayish-white, ka sebōpeho sa sekala se setle.Mokhoa oa eona oa molek'hule ke (H 2 KAl 3 (SiC4) 3. Sebopeho sa Themineral se batla se le bonolo 'me litaba tsa lintho tse chefo li tlaase haholo , Ha ho na lisebelisoa tsa radioactive, tse ka sebelisoang e le lintho tse tala.
