Qhov sib txawv ntawm quartz xuab zeb, silica xuab zeb thiab silica

Quartz xuab zeb thiab silica xuab zeb yog tsim los ntawm silicon dioxide. Lawv txawv raws li cov ntsiab lus ntawm silica. Silica cov ntsiab lus siab tshaj 98.5% yog hu ua quartz xuab zeb, thiab silicon dioxide cov ntsiab lus hauv qab 98.5% yog hu ua quartz xuab zeb. Silica, cov tshuaj formula yog sio2. Muaj ob hom silica hauv qhov xwm txheej: Du crystalline silica thiab amorphous Zhi silica. Vim qhov sib txawv ntawm cov qauv siv lead ua kob, crystalline silica tuaj yeem muab faib ua peb hom: quartz, tridymite thiab cristobalite. Silica yog siv los ua iav ca, iav khoom, foundry xuab zeb, iav fiber, ceramic xim glaze, anti-xeb sandblasting, lim xuab zeb, flux, refractory cov ntaub ntawv thiab lub teeb yuag ua npuas ncauj.

Quartz xuab zeb yog quartz particle uas tawg mus rau hauv pob zeb dawb quartz. Quartzite yog cov ntxhia uas tsis yog xim hlau. Nws yog ib qho nyuaj, hnav-tiv taus thiab tshuaj lom neeg ruaj khov silicate ntxhia. Qhov tseem ceeb ntawm cov pob zeb hauv av yog silica. Quartz xuab zeb yog milky dawb los yog tsis muaj xim thiab translucent. Nws hardness yog 7. Quartz xuab zeb yog ib qho tseem ceeb muaj ntxhia raw cov ntaub ntawv, uas tsis yog-tshuaj lom cov khoom, lug siv nyob rau hauv iav, casting, ceramics thiab refractory ntaub ntawv, smelting ferrosilicon, metallurgical flux, metallurgy, kev tsim kho, tshuaj kev lag luam, yas, roj hmab, abrasives, lim cov ntaub ntawv thiab lwm yam kev lag luam.

Quartz nyob rau hauv silica xuab zeb yog lub ntsiab ntxhia tivthaiv thiab particle loj. Raws li kev sib txawv ntawm cov mining thiab kev ua, 0.020mm-3.350mm refractory hais tuaj yeem muab faib ua cov silica xuab zeb thiab ntuj silica xuab zeb, xws li cov xuab zeb ntxuav, ntxuav xuab zeb thiab xaiv (flotation) xuab zeb. Silica xuab zeb yog ib qho nyuaj, hnav-tiv taus thiab tshuaj lom neeg ruaj khov silicate ntxhia. Nws cov ntxhia tseem ceeb yog silicon dioxide. Silica xuab zeb yog milky dawb los yog tsis muaj xim thiab translucent.
