Amatafari ya silika yamashanyarazi ni acide acide kandi afite aside irwanya isuri. Amatafari ya Slica yangiritse munsi yumutwaro agera kuri 1640 ~ 1690 ℃, bigaragara ko ubushyuhe bwambere bworoheje ari 1620 ~ 1670 ℃ naho ubucucike nyabwo ni 2,35g / cm3. Amatafari yumuriro wa Silicon arashobora gukora mubushyuhe bwo hejuru mugihe kirekire kandi agakomeza guhagarara neza ntagahinduka. Amatafari yo gusubiramo silicon arimo ibice birenga 94% bya SiO2. Amatafari ya silike afite imbaraga zo hejuru yubushyuhe bwo hejuru hamwe nubushyuhe buke bwo guhangana nubushyuhe. Amatafari yumuriro wa silikate akozwe mubutare bwa silika karemano nkibikoresho fatizo, byongewemo minervalize ikwiye kugirango iteze imbere quartz mumubiri wicyatsi ihinduka tridymite hanyuma irasa buhoro buhoro binyuze mubushyuhe bwa 1350 ~ 1430 ℃ mukugabanya ikirere. Iyo ubushyuhe bugera kuri 1450 ℃, hari konti 1.5 ~ 2,2% yo kwaguka kwinshi. Ibi nyuma yo kwaguka bizatuma gukata-gufunga bifunze kandi byemeze ko ubwubatsi bugumana umwuka mwiza udahinduka hamwe nimbaraga zubaka.
Amashanyarazi ya Silicon ni amatafari yangiritse arimo silika irenga 93%, 50% -80% ya tridymite, 10% -30% ya cristobalite, quartz nibirahuri, hafi 5% -15%. Amabuye y'agaciro ya matafari ya silikatike ni nini cyane ya quartz na quartz, kimwe na quartz na vitreous. Ibipimo bya Quartz, Quartzite Quartz hamwe na quartz isigaye ihinduka cyane mubunini bitewe nihinduka ryimiterere ya kirisitiya ku bushyuhe buke, bityo rero ubushyuhe bwumuriro bwamatafari ya silikate yamenetse ni mabi mubushyuhe buke. Muburyo bwo gukoresha, munsi ya 800 ℃ kugirango ushushe ubushyuhe no gukonja, kugirango wirinde gucika. Ntugomba rero kuba munsi ya 800 ℃ ubushyuhe bwo gusimbuka kw'itanura.
Amatafari yumuriro wa silikate akozwe muri quartzite hamwe na minervaliste nkeya. Iyo yatwitse ubushyuhe bwinshi, amatafari ya silika yamatafari yubutare agizwe nubunini bwa quartz, quartzite quartz, ikirahuri hamwe nizindi ngingo zingingo zakozwe mubushyuhe bwinshi, naho AiO2 irenga 93%. Mu matafari meza ya silika yatwitse, ibikubiye muri kwartz nini ni hejuru, bingana na 50% ~ 80%. cristobalit yari ikurikiraho, ihwanye na 10% kugeza 30%. Ibiri muri quartz hamwe nicyiciro cyikirahure bihindagurika hagati ya 5% na 15%

Amatafari yumuriro wa Silica akoreshwa cyane nkibikoresho byo kwangiriza urukuta rukingira urugereko rwa kokiya no gutwika mu ziko rya kokiya, icyumba gisubiramo ndetse nu mufuka wa slag mu gukora itanura ryugururiwe itanura, itanura ryo mu rwobo hamwe n’itanura rishonga ibirahure, hamwe n’ahantu hafite uburemere no hejuru muri ceramic gucana itanura. Amatafari ya silikatike arashobora kandi gukoreshwa ahantu hafite uburemere bwubushyuhe bwo hejuru no hejuru ya acide ifungura itanura.
