Waa maxay dhalada barafka?
Glass Porosalet waa nooc galaas ah oo leh silica iyo boron trioxide madaama ay yihiin kuwa ka kooban muraayadaha musqulaha waaweyn. Muraayadaha barafka leh waxaa lagu yaqaanaa isku-darka aad u hooseeya ee ballaarinta kuleylka (× 10⁻⁶⁻⁶ k⁻¹ 20 ° C), taasoo ka dhigeysa inay ka sii adkaansan yihiin shoogga kuleylka ah ee ka badan galaaska kale ee ugu badan. Quraaradda noocan oo kale ah waxaa loo istaagayaa walwal kuleylka oo ka yar waxayna u adkeysan kartaa kala duwanaanshaha heerkulka iyada oo aan jabin qiyaastii 165 ° C (297 ° F). Waxaa caadi ahaan loo adeegsadaa dhismaha dhalada dib-u-habeynta iyo sidoo kale nalka, elektiroonigga iyo kariye.
