Sericite
I-Sericite luhlobo olutsha lwezimbiwa zemizi-mveliso enesakhiwo esinelayiti, esiyi-subspecies ye-muscovite kwintsapho ye-mica enezikali ezintle kakhulu.Ubuninzi buyi-2.78-2.88g / cm 3, ubunzima buyi-2-2.5, kunye ne-diameter-thickness ratio yi-50. Inokwahlulwa ibe yi-flakes encinci kakhulu, kunye ne-silk luster kunye nemvakalelo egudileyo, egcwele u-elasticity, ukuguquguquka, ukuxhathisa i-asidi kunye ne-alkali, ukugquma kombane okunamandla, ukumelana nobushushu (ukuya kwi-600 o C), kunye ne-coefficient ephantsi yokwandiswa kwe-thermal, kunye nomphezulu unokumelana okunamandla kwe-UV, ukuxhathisa okulungileyo kunye nokumelana nokunxiba.I-elastic modulus yi-1505-2134MPa, amandla e-tensile yi-170-360MPa, amandla e-shear yi-215-302MPa, kunye ne-thermal conductivity yi-0.419-0.670W.(MK) -1.Inxalenye ephambili yi-potassium silicate aluminosilicate mineral, eyisilivere-emhlophe okanye i-grayish-white, ngendlela yezikali ezintle.I-formula yayo ye-molecular (H 2 KAl 3 (SiC4) 3. Ukubunjwa kwe-Themineral kulula kwaye umxholo wezinto ezinobuthi uphantsi kakhulu , Akukho zixhobo ze-radioactive, zingasetyenziswa njengezinto eziluhlaza.
