Crystal yog xim tsis muaj xim thiab pob tshab loj quartz siv lead ua ntxhia. Nws lub ntsiab tshuaj lom neeg yog silicon dioxide thiab nws cov tshuaj lom neeg yog tshuaj SiO2. Cov siv lead ua tsis muaj xim, liab dawb, siv lead ua rhinestones daj, ntsuab thiab pa taws, thiab lwm yam. Hardness 7, nkig, siv lead ua rhinestones tsis muaj kev txav; siv lead ua ceev 2.56-2.66 g / cm3, siv lead ua yooj yim Performance index 1.544-1.553, tsis yog dhau ntawm qhov ntau; siv lead ua dispersion 0.013, siv lead ua rhinestones siv lead ua melting point 1713 ℃.
Thaum nws dawb huv, nws ua rau cov xim tsis muaj xim thiab pob tshab, thaum nws muaj kab kawm Al, Fe, Crystal rhinestones thiab lwm yam, nws yog ntshav, xim daj, xim av, thiab lwm yam Tom qab irradiating cov kab kawm, ntau hom xim chaw yog tsim, cov siv lead ua rhinestones ua rau muaj xim sib txawv, xws li ntshav, daj, xim av, Paj yeeb thiab lwm yam Muaj cov khoom sib xyaw hu ua cov khoom siv ua khoom siv, cov khoom siv lead ua rhinestones xws li plaub hau plaub, ntsuab dab, thiab lwm yam Cov ntawv suav yog rutile, tourmaline, actinolite, mica, chlorite , siv lead ua rhinestones thiab lwm yam.
Yog tias koj xav paub qhov txawv pob zeb diamond, zircons, muaju, thiab iav, cov hom ntoo zoo nkauj, siv lead ua rhinestones hauv chav kuaj, muaj ntau yam twj paj nruag, xws li refractometers, infrared spectroscopy, etc. Feem ntau, siv lead ua rhinestones yog tias qhov muag liab pom qhov txawv, feem ntau siv cov txuj ci kho qhov muag, Txoj hauv kev yog raws li nram no: muab txoj kab ncaj ncaj rau ntawm ib daim ntawv, siv lead ua rhinestones muab tso rau plaub lub pob zeb kub rau saum, lub pob zeb diamond tuaj yeem' t pom cov kab hauv qab, siv lead ua rhinestones lwm peb tuaj yeem pom txoj kab hauv qab, qhov no yog kom paub qhov txawv ntawm lub pob zeb diamond. Kev hloov pauv cov hniav nyiaj hniav kub, zircon Thaum cov siv lead ua tig, siv lead ua rhinestones cov kab yuav khoov, tab sis iav yuav tsis
