Acid refractory tsuas yog tsim los ntawm tridymite, cristobalite thiab ib qho me me ntawm cov seem quartz thiab iav theem.
Cov ntsiab lus silica yog ntau tshaj 94 feem pua. Qhov ceev ceev yog 2.35g / cm3. Nws muaj peev xwm tiv taus acid slag yaig. Siab kub siab zog. Qhov pib kub ntawm softening nyob rau hauv load yog 1620-1670 degree . Kev siv sijhawm ntev ntawm qhov kub thiab txias yuav tsis deform. Tsawg thermal poob siab stability (1 mus rau 4 zaug ntawm kev sib hloov cua sov hauv dej). Ntuj silica yog siv los ua raw cov ntaub ntawv, thiab ib qho tsim nyog tus nqi ntawm mineralizer yog ntxiv los txhawb kev hloov ntawm quartz hauv lub cev ntsuab rau hauv tridymite. Nws maj mam raug rho tawm haujlwm ntawm 1350-1430 degree hauv qhov chaw txo qis. Thaum rhuab mus rau 1450 degree, tag nrho ntim nthuav dav yog li 1.5 ~ 2.2 feem pua. Qhov kev nthuav dav seem no yuav ua rau cov slits kaw thiab xyuas kom cov masonry muaj huab cua nruj thiab lub zog zoo.
