Fiber na-emegharị emegharị maka stovu na-ekpo ọkụ

Nke a nke anyị ga-anọgide na-ewebata e ji mara nke refractory eriri.

1. Nnukwu okpomọkụ na-eguzogide
2. Low thermal conductivity, obere njupụta.
The thermal conductivity n'okpuru elu okpomọkụ dị ala. Na 100 Celsius C, ihe na-ekpo ọkụ nke eriri refractory bụ naanị 1/10 ~ 1/5 nke brik na-atụgharị, na 1/20 ~ 1/10 nke brik ụrọ nkịtị. N'ihi njupụta ya dị ala, enwere ike ibelata ibu na ihe owuwu nke kiln nke ukwuu.
3. Ezigbo nkwụsi ike nke kemịkal
Ewezuga alkali siri ike, fluorine na phosphate, ọtụtụ kemịkalụ enweghị ike imebi ya.
4. Ezigbo ujo na-eguzogide okpomọkụ
Mgbochi ujo na-ekpo ọkụ nke eriri refractory dị mma karịa nke brik na-atụgharị.
5.Obere okpomọkụ ike
