Siv lead ua dag (siv lead ua neeg tsim) yog dab tsi

May 25, 2016

Tus dag siv lead ua-ua iav, los sis hu ua siv lead ua iav, uas zoo tib yam iav (silica tivthaiv) tau ntxiv 24% ua oxide, nws yuav tau brightness thiab transparency zoo ib yam li ntuj siv lead ua. Siv lead ua neeg tsim ntaub ntawv raw quartz xuab zeb ntawm hauv kev ua hauj lwm li cas abstraction, phais elaborate technology hab flawless burnish kung fu yog ua los ntawm siv lead ua dag ntshiab thiab pob tshab, tuaj ua ntxiv rau tus tsis muaj ntuj siv lead ua. Siv lead ua dag ntxiv xov hais xws li hlau lead split txhaj yuav txhim khu lub teeb, ntau siv lead ua noble qhia. Cov khoom siv tes ua vim txoj kev no nyuab dag siv lead ua, kev txawj, thiab ib txhia kuj kim kim tshaj tus nqi siv lead ua ntuj. Molecular mis mos: xwm α-SiO2: α artificially zus siv lead ua. Α quartz nyob rau hauv kev kub siab ua neej nyob rau ib qho tshuaj alkaline. Siv lead ua qauv yog ntau yam dua, nrog rau cov menyuam ntxaib, ib lub qhov, inclusions kom tsawg dua. Siv khiav cov solubility decreases nrog zuj zus lawm kub, tus siv lead ua α quartz tau tau zus hydrogen, sodium hydride los yog kua sodium carbonate. Synthesis siab 16.5MPa, kub 400 ℃. Nyob rau hauv lub (001) basal dav hlau loj npaum li cas ntawm 1.27μm / nruab hnub. Mas siv electronics kev lag luam, ultrasonic generator, kho qhov muag pab li sawv daws thiab seev analytical. Txheem nta tseev tsim ntiaj teb ua oxide ntawv 24%, ces cov tshuaj khoom ntawm tus zoo neeg tsim siv lead ua, piv nrog zoo tib yam iav, hnyav mas, xav ntau hauv; lub refractive loj index yuav kis tau ntawm kaum yeeb yuj spectrum of xim; siab hardness, coj. Siv uas muaj 24% ua iav oxide hmoov txhuas los ntawm refining, impurities, cua tshuab, tes polished, fine carving, yuav qhia kom paub high-grade zoo ua iav Art, lub teeb duab puab ntawm seb yuav muaj kev cuam tshuam cov xim. Thoob ntiaj teb qauv mus iav muaj tswvyim nruj, yog iav: namely, iav zoo tib yam khoom. Siv lead ua: ua iav los siv lead ua hu ua oxide txhuas cov ntsiab lus ntawm 24%. Yog li ntawd, muaj 24% hlau lead oxide kev zoo taug txhuas iav lav.
