Cov iav frosted cov khoom yog cov hmoov txhuas-dawb iav hmoov rau kev npaj rau nruab nrab slurry thiab kev tsim khoom txoj kev. Nws yog ua los ntawm tsawg kawg barium oxide (BaO), boron oxide (B 2 O 3 ), zinc oxide (ZnO), sodium oxide (Na 2 O), thiab lub cev ua los ntawm melting thiab pulverizing potassium oxide (K 2 O) ; cov qauv kev lag luam ntawm cov hmoov txhuas-dawb iav hmoov muaj xws li hnyav cov khoom siv raw khoom raws li cov lus muaj pes tsawg leeg thiab qhov hnyav; siv tag nrho cov khoom siv raw coj los ntsuas; melting cov khoom siv sib xyaw ua kom yob kom txias qhov sib tov tom qab yaj tag rau hauv daim ntawv tawg iav; thaum kawg sib tsoo lub khob ntawv ua hmoov thiab sieving.
Quartz xuab zeb yog qhov tseem ceeb kev lag luam ntxhia cov khoom siv, cov khoom tsis muaj tshuaj lom neeg. Nws yog dav siv nyob rau hauv ntau txhiab iav, casting, ceramics thiab refractory cov ntaub ntawv, ferrosilicon, metallurgical flux, metallurgy, kev tsim kho, tshuaj lom neeg, plastics, roj hmab, abrasives thiab lwm yam lag luam. , Tsheb nqaj hlau thauj, thauj dej.
