Borosilicate iavyog ib hom ntawmiavnrogsilicathiabboron trioxideraws li lub ntsiab iav-sib sau ua ke. Borosilicate tsom iav tau paub tias muaj qis heevcoefficients ntawm thermal expansion(~3×10−6K−1li ntawm 20 ° C), ua rau lawv tiv tausthermal poob siab, ntau dua li lwm yam kev siv iav. Cov iav zoo li no tsis tshua raugthermal kev nyuaj siabthiab feem ntau yog siv rau kev tsim kho ntawmreagent fwjCov. Borosilicate iav raug muag hauv qab cov npe lag luam liBorcam,Borosil,DURAN, Suprax, Simax, BSA 60, BSC 51 (Los ntawm NIPRO), Heatex,Lub siab kawg,Xob,Refmex,Kimble, thiab qee yam (tab sis tsis yog tas nrho) cov khoom muag hauv qab cov npe lag luamPyrex.
