Corundum mullite zvidhinha imhando yezvidhinha zvinoramba zvakagadzirwa kubva pakuchena kwepamusoro kana kuchena zvinhu, zvakare corundum mullite block ndeye yakakwira alumina yemoto zvidhinha yakagadzirwa necorundum uye mullite main crystalline chikamu. Chinhu chikuru checorundum mullite zvidhinha inotengeswa kunze kweplate corundum, yakakwira yakachena fused corundum, inotora yepamusoro yepamusoro poda yekuwedzera tekinoroji, inogadzirwa neyakasanganiswa zvinhu, kuomesa, kuumba uye kupiswa mumoto wekushisa wekuvhara.
Corundum mullite zvidhinha inogadzirwa neyakagadzirwa mullite zvidhinha uye mullite zvimedu zvekuunganidza zvinhu zviripo, uye alpha Al2O3 poda yehupfu, inogona zvakare kusanganiswa kana sintered corundum zvimedu kuunganidza zvinhu, synthetic mullite poda yehupfu. Iyo yakaunganidzwa uye hupfu inosanganiswa maererano nechiyero chakati uye saizi yezviyo. Iyo tsvina yedoro yepepa pulp ine sulfite inoshandiswa sechinhu chinosunga, uye zvinhu zvinowedzerwa mune imwe nzira.Zvakazara zvakasanganiswa uye kunyange, ne friction press kana hydraulic press brick molding machine.Adobe mushure mekuoma, kupisa mukati 1650 ~ 1750 ℃.

Kazhinji, cordundum mullite zvidhinha yakakamurwa kuita sintering uye yakasanganiswa zvidhinha, mutengo wemhando mbiri dze corundum mullite refractory zvidhinha zvakasiyana kwazvo mumusika, mutengo uri muhuwandu hwezviuru kusvika ku10,000. Tinokurudzira zvakasiyana corundum mullite moto zvidhinha zvinofanira kusarudzwa maererano nezvikamu zvakasiyana zvemoto, kwete kungovandudza hupenyu hwevira, asiwo kuderedza mari.
Cordundum mullite zvidhinha inogona kunanga kusangana nemurazvo, spalling kuramba, yakakwirira tembiricha inodzivirira, inogona kushandiswa seyekudzivirira kupisa kwekushisa kwakanyanya kwemaindasitiri choto lining. uyewo corundum mullite moto zvidhinha zvinogona kushandiswa seimwe maindasitiri choto basa layer, rinonyanya kushandiswa muindasitiri yepetrochemical, hombe uye yepakati-saizi ammonia gasifier uye magineti zvinhu zvegasi choto chine zvinhu, tembiricha yakakwira maindasitiri kiln zvivakwa zvinhu, nezvimwe.
