Fluorite suav hais tias yog kev lag luam muaj ntxhia. Nws yog dav siv hauv hlau smelting, ceramics thiab hmo ntuj pom kev. Cov ntxhia hauv qab no kuj tau siv los ua cov ntsiab lus nyiaj-kub, tab sis tsuas yog cov nqaj zoo nkauj xwb.
Keeb Kwm
Cov tshuaj fluorite nyob nrog pab pawg ntawm cov halides, muaj cov subclass ntawm cov tshuaj fluoride. Nws tsis muaj ib yam dab tsi ntau tshaj calcium fluoride (CaF2). Nws yog feem ntau hu ua fluorspar.
Nws yog ntawm qhov magmatic xwm, nws yog suav hais tias yog lub pob zeb me hauv cov pob zeb uas tsim tom qab huab hwm coj los ntawm lub roob hluav taws txias. Cov tshuaj fluorite feem ntau yog ib qho txiaj ntsig ntawm kev txav ntawm cov tshuaj fluorine los ntawm cov quav. Kev hla dhau los ntawm cov kab nrib pleb hauv cov pob zeb, lawv ua ib lub pob zeb crystallized.
Cov tshuaj fluorite tuaj yeem pom hauv hydrothermal veins. Nws tseem tsim ua pawg hauv limestones thiab dolomites. Nws tshwm sim ob qho tib si hauv daim ntawv ntshiab thiab hauv kev sib txuas nrog ntau yam hlau hlau, tshwj xeeb, hlau lead-zinc. Ib tug xov tooj ntawm granite thiab pegmatite ntau yam muaj cov tshuaj fluorite me me. Nws yog los ntawm lawv tias nws cov iav pom kev zoo yog cov mined.
Cov tshuaj fluorite tseem tuaj yeem ua ke nrog ntau yam zaub mov, suav nrog barite, calcite, celestine, cassiterite, dolomite, galena, quartz, thiab sphalerite.
Kis mus
Muaj fluorite ntau nyob rau hauv cov xwm. Hais txog nws cov khoom lag luam, peb lub xeev tseem ceeb hauv ntiaj teb - Tebchaws Mongolia, Mexico thiab Suav. Tsis tas li, fluorite tso nyiaj ntawm cov khoom ntim ntau yog nyob hauv lub teb chaws Yelemees, Switzerland thiab Ltalis, Tebchaws Asmeskas, thiab Sweden.
Tseem muaj qhov tso nyiaj ntawm cov pob zeb hauv av no hauv teb chaws Russia. Lawv nyob hauv Primorye thiab Chita cheeb tsam. Tsuas yog cov muaj fluorite tam sim no muaj ntau heev.
Khoom
Fluorite yog qhov txawv txav ntawm cov xim sib txawv. Feem ntau muaj xim xiav, ntshav, ntsuab lossis daj, tsis tshua muaj xim liab, dub, liab lossis txawm tias xim tsis muaj xim. Qee yam ntawm lub pob zeb no yog banded. Lawv tuaj yeem tseem muaj zonal xim.
Txhua cov tshuaj fluorite muaj cov xim hlau uas yog xim hlau thiab atoms fluorine ob. Cov qauv siv lead ua yooj yim ntawm cov pob zeb no yog qhov cubic. Cov qauv sab nraud kuj yog feem ntau cubic, txawm hais tias dodecahedrons thiab octahedrons pom. Crystals feem ntau yog ntxaib.
Fluorite yog cov ntxhia mos mos. Ntawm Mohs nplai ntawm hardness, nws tsuas muaj 4 lub ntsiab lus. Nws tuaj yeem raug txhuam yooj yim nrog rab riam hauv chav ua noj. Cov ntxhia khoom siv tsis tshua muaj siab rau qhov kub thiab tawg tau yooj yim hla qhov hluav taws qhib. Ntawm 1360 ° C, nws pib yaj.
Cov tshuaj fluorite muaj cov cim fluorescence muaj zog; Txawm li cas los xij, cov cuab yeej no muaj ntau yam nyob ntawm seb hom qias neeg hauv cov qauv.
Lub npe ntawm lub pob zeb los ntawm lo lus Latin fluere, uas txhais tau tias "ntws." Nws yog vim muaj peev xwm los txo qis kub ntawm cov melts rau uas nws tau ntxiv. Qhov ntau ntawm cov kev thov kev lag luam ntawm fluorite yog qhov dav heev. Txawm li cas los xij, nws yog feem ntau siv hauv kev tsim cov tshuaj hydrofluoric acid.
Kev siv fluorite hauv cov hniav nyiaj hniav kub yog txwv vim nws cov khoom: nws yog mos thiab yooj yim khawb. Jewelers feem ntau cabochon nws thiab siv txheej txheej tiv thaiv ntawm cov tawv tawv quartz.
