Chemistry of nonmetallic elements III. Minerals uas muaj fluorine suav nrog fluorite, CaF2, cryolite, Na3AlF 6, thiab fluoroapatite, Ca5(PO4)3F.
Cryolite yog dab tsi?
Cryolite, tsis muaj xim rau dawb halide ntxhia, sodium aluminium fluoride (Na 3 AlF 6). Nws tshwm sim hauv qhov tso nyiaj loj ntawm Ivigtut, Greenland, thiab me me hauv Spain, Colorado, Asmeskas, thiab lwm qhov.
Cov hlau twg yog muab rho tawm los ntawm cryolite?
Aluminium oxide tsis yaj hauv dej, tab sis nws yaj hauv molten cryolite. Qhov no yog ib qho txhuas compound nrog qis melting point tshaj aluminium oxide. Kev siv cov cryolite txo qee cov nqi hluav taws xob koom nrog hauv kev rho tawm aluminium.
Cryolite hauv chemistry yog dab tsi?
: cov ntxhia uas muaj cov tshuaj fluoride ntawm sodium thiab txhuas pom tshwj xeeb tshaj yog nyob rau hauv Greenland feem ntau yog dawb cleavable masses thiab yav tas los siv los ua ib qhov chaw ntawm txhuas.
Lub luag haujlwm ntawm cryolite hauv txhuas purification yog dab tsi?
Lub luag haujlwm ntawm cryolite hauv txhuas purification yog dab tsi? Nyob rau hauv nws daim ntawv molten, nws dissolves cov bauxite, tso cai rau txhuas los ua electrolytically ntawm qhov kub thiab txias.
