Izici zika izitini ezikhanyisayo

1. Ukumelana nezinga lokushisa eliphezulu: Ikakhulukazi isetshenziselwa ukwakha iziko lokuncibilikisa, futhi ingamelana nezinga lokushisa eliphezulu lika-1580°C-1770°C.

2. Izinga lokushisa lokuthambisa liphezulu.

3. Ukumelana nokugqoka kanye nokumelana nokugqwala. Ukuthatha izitini eziphakeme ze-alumina njengesibonelo isitini esiphikisayo esingathathi hlangothi esingamelana nokuguguleka kwe-asidi nezitini eziphikisayo ze-alkali.

4. I-Thermal conductivity: Ngaphansi kwesimo se-gradient yokushisa kweyunithi, izinga lokugeleza lokushisa endaweni ngayinye yeyunithi yento lihlobene ne-porosity.

5. Ubuningi bobuningi: isisindo sevolumu yeyunithi, ukuminyana okuphezulu, okubonisa ukuthi ukuminyana kuhle, amandla angase abe phezulu.
