Khoom cua quartz

Yuav cov gemstones hauv ntuj hauv peb lub khw


Tsis yog txhua txhua hom ntawm quartz yog ib txwm muaj tshwm sim. Vim tias cov kua siv lead ua feem ntau ntxaib, hluavtaws quartz yog tsim rau siv hauv kev lag luam. Loj, flawless, tib cov muaju yog synthesized nyob rau hauv autoclave ntawm cov txheej txheem hydrothermal

Hydrothermal quartz

Synthetic quartz suav nrog ntau hom kev kawm ntawm crystallizing tshuaj los ntawm kev kub siab aqueous kev daws teeb meem ntawm siab vapor pressures, tseem hu ua hom kev hydrothermal, hydrothermal yog ntawm keeb kwm geologic. Geochemists thiab mineralogists tau kawm hydrothermal quartz equilibria txij thaum pib ntawm lub xyoo pua nees nkaum.

Kev ntsuas hluav taws xob

Hydrothermal hluavtaws tuaj yeem txhais tau tias yog cov qauv ntawm cov khoom coj los ua ke ntawm cov khoom siv hluav taws xob ib leeg uas nyob ntawm solubility ntawm cov zaub mov hauv cov dej kub hauv qab qhov siab. Txoj kev loj hlob ntawm quartz siv ua rau hauv ib lub tshuab muaj cov hlab siab steel hu ua autoclave, uas cov khoom noj muaj txiaj ntsig nrog rau dej. Qhov ntsuas kub yog tswj xyuas ntawm qhov xaus sib txawv ntawm chav ua kom loj hlob. Ntawm qhov kub tshaj kawg cov khoom noj khoom haus daws teeb meem, thaum lub sijhawm txias nws yog tso rau ntawm cov noob siv lead ua, loj hlob rau cov xav siv lead ua.

Qhov zoo ntawm cov khoom cua hydrothermal quartz txoj kev

Qhov zoo ntawm cov txheej txheem hydrothermal dua li lwm hom kev siv lead ua muaj peev xwm suav nrog kev muaj peev xwm los tsim cov theem crystalline uas tsis ruaj khov ntawm qhov chaw melting. Tsis tas li, cov ntaub ntawv uas muaj lub siab vapor nyob ze lawv cov ntsiab lus melting tuaj yeem cog los ntawm hom hydrothermal. Cov txheej txheem kuj yog tshwj xeeb tsim rau kev loj hlob ntawm loj zoo-zoo muaju quartz thaum tswj kev tswj hwm lawv cov qauv. Qhov tsis zoo ntawm txoj kev suav nrog qhov xav tau ntawm autoclaves kim, thiab qhov tsis muaj peev xwm ntawm kev saib xyuas qhov ci ntsa iab thaum nws loj tuaj yog tias siv lub raj siv steel. Muaj cov autoclaves ua los ntawm cov iav tuab-phab ntsa, uas tuaj yeem siv mus txog 300 ° C thiab 10 tuav.

Khoom cua quartz keeb kwm

Thawj qhov kev tshaj tawm ntawm hydrothermal kev loj hlob ntawm cov muaju yog los ntawm German geologist Karl Emil von Schafhäutl (1803 – 1890) hauv 1845 nws loj hlob microscopic muaju hauv lub qhov cub txias.
