Cov iav borosilicate siab(tseem hu ua iav tawv), yog tus cwj pwm los ntawm kev siv iav los coj hluav taws xob ntawm qhov kub siab. Lub iav raug yaj los ntawm kev cua sov sab hauv ntawm lub iav thiab ua tiav los ntawm cov txheej txheem tsim khoom siab heev.
Tus coefficient rau thermal expansion yog (3.3 ± 0.1) x 10-6/K, tseem hu ua "borosilicate iav 3.3". Nws yog cov khoom siv iav tshwj xeeb nrog qhov nrawm qis, tiv taus kub siab, muaj zog siab, tawv siab, lub teeb siab
Kev xa hluav taws xob thiab kev ruaj khov tshuaj lom neeg siab. Vim nws ua tau zoo heev, nws yog siv dav hauv lub zog hnub ci, kev lag luam tshuaj lom neeg, kev ntim tshuaj, lub teeb hluav taws xob, cov hniav nyiaj hniav kub thiab lwm yam lag luam.
