Borosilicate iav yog hom iav nrog silica thiab boron trioxide raws li lub iav ua tus qauv. Borosilicate tsom iav yog paub tias muaj cov coefficients tsawg ntawm thermal expansion (~ 3 × 10 -6 K -1 tom 20 ° C), ua rau lawv tiv taus thermal shock , ntau tshaj li lwm yam iav. Cov iav no tsis tshua raug thermal kev ntxhov siab thiab feem ntau yog siv rau kev tsim kho ntawm cov tshuaj tsuag reagent . Borosilicate iav yog muag hauv cov lag luam xws li Borcam , Borosil , DURAN , Suprax, Simax, BSA 60, BSC 51 (By NIPRO), Heatex, Endural , Schott , Refmex , Kimble , thiab qee qhov (tab sis tsis yog txhua yam) muag hauv qab pauv npe Pyrex .
