Soda txiv qaub iav feem ntau hu ua silicate iav, nws cov khoom tseem ceeb yog silicon dioxide (SiO2), thiab tseem muaj qee yam ntawm sodium oxide (Na2O) thiab calcium oxide (CaO), thiab qee cov khoom xyaw ntxiv. Vim tias nws muaj sodium oxide thiab calcium oxide, nws cov thermal expansion coefficient yog me me, yog li nws muaj thermal shock kuj zoo; Nyob rau tib lub sijhawm, dej qab zib txiv qaub iav muaj lub teeb kis tau zoo thiab tshuaj lom neeg ruaj khov, yog li nws yog siv los tsim cov khoom siv tshuaj, cov cuab yeej kho qhov muag, cov cuab yeej kho mob thiab lwm yam muaj ntau yam kev siv.
Lub ntsiab Cheebtsam ntawm siab borosilicate iav yog silicon oxide (SiO2) thiab boron oxide (B2O3), thiab kuj muaj ib co lwm yam auxiliary Cheebtsam. Piv nrog dej qab zib-txiv qaub iav, siab borosilicate iav muaj ib qho me me thermal expansion coefficient, yog li nws muaj cua sov zoo dua thiab thermal shock resistance; Nyob rau hauv tas li ntawd, siab borosilicate iav muaj zoo mechanical zog thiab tshuaj stability, thiab yog ntau pob tshab thiab Radiation resistant. Yog li ntawd, nws yog dav siv nyob rau hauv nuclear kev lag luam, optoelectronic technology, semiconductor kev lag luam thiab lwm yam teb.
Txawm hais tias ob qho tib si dej qab zib-txiv qaub iav thiab borosilicate iav yog cov khoom siv tsis zoo amorphous, lawv qhov sib txawv nyob hauv lawv cov tshuaj muaj pes tsawg leeg thiab cov khoom. Soda txiv qaub iav yog tsim rau cov sij hawm uas xav tau tshuaj stability thiab lub teeb kis tau tus mob, thaum lub siab borosilicate iav yog tsim nyog rau lub sij hawm uas yuav tsum tau kub kub kuj thiab hluav taws xob tsis kam.
