Borosilicate Iav yog dab tsi?
Borosilicate iav yog ib hom iav nrog silica thiab boron trioxide ua cov khoom tseem ceeb uas tsim cov iav. Borosilicate iav paub tias muaj cov coefficients qis heev ntawm kev nthuav dav thermal (≈3 × 10⁻⁶ K⁻¹ ntawm 20 °C), ua rau lawv tiv taus thermal shock ntau dua li lwm cov iav. Cov iav zoo li no raug kev ntxhov siab thermal tsawg dua thiab tuaj yeem tiv taus qhov sib txawv ntawm qhov kub thiab txias yam tsis muaj kev tawg ntawm kwv yees li 165 °C (297 °F). Nws feem ntau siv rau kev tsim cov fwj tshuaj reagent thiab flasks nrog rau teeb pom kev zoo, khoom siv hluav taws xob thiab cov khoom siv ua noj.
