lepidolite (thia mica)
Lepidolite yog cov pob zeb lithium ntau tshaj plaws thiab cov ntxhia tseem ceeb rau kev rho tawm lithium.Nws yog ib qho yooj yim aluminosilicate ntawm poov tshuaj thiab lithium, uas belongs rau mica minerals.Feem ntau, lepidolite tsuas yog ua hauv granite pegmatite.Lub ntsiab tivthaiv ntawm lepidolite yog kli1 5Al1.5 [alsi3o10] (F, oh) 2, muaj Li2O ntawm 1.23-5.90%, feem ntau muaj rubidium, cesium, thiab lwm yam. Monoclinic system.Cov xim yog ntshav thiab liab, thiab tuaj yeem ua rau lub teeb tsis muaj xim, nrog pearl luster.Nws yog feem ntau nyob rau hauv nplua scale aggregate, luv kem, me daim ntawv aggregate los yog loj phaj siv lead ua.Lub hardness yog 2-3, lub ntiajteb txawj nqus tshwj xeeb yog 2.8-2.9, thiab hauv qab cleavage yog heev tiav.Thaum yaj, nws tuaj yeem ua npuas dej thiab tsim cov nplaim liab lithium.Insoluble hauv acid, tab sis tom qab yaj, nws tuaj yeem cuam tshuam los ntawm acids.
