He matū kore-waro te waikura konumohe, ko tōna tauira matū ko A1203, he matū tino mārō me te ira rewa o te 2054°C me te ira koropupū o te 2980°C. He tioata ionic ka taea teionizedi ngā pāmahana tiketike, ā, e whakamahia whānuitia ana i roto i te hanga rauemi ātete ahi. He rite tonu te matū o te alumina kua whakapūkaratia me te alumina, engari nā ētahi tikanga whakaputa me ētahi atu rerekētanga tukanga, nō reira he rerekētanga te mahi a te tokorua i roto i te whakamahinga, ā, ka rerekē anō hoki.
Ko te konumohe te konumohe matua o te konumohe i roto i te taiao, ka kuruhia, ka whakakīia ki te wairewa konutai hauwai wera nui hei whiwhi i te wairewa konutai alumina; ka tātarihia hei tango i te toenga, ka whakamatao i te tātari, ka tāpirihia ngā tioata konumohe hauwai, ā, i muri i te whakaoho roa, ka pirau te wairewa konutai alumina ka whakapūpū i te konumohe hauwai; ka wehea te pūpū ka horoia, kātahi ka whakapūpū i te 950-1200°C hei whiwhi i te paura alumina momo-c, ko te Alumina kua whakapūpūtia he alumina momo-c. He tino teitei ngā ira rewa me ngā ira kohua.
Kāore te alumina kua whakapūkaratia e rewa i roto i te wai me te waikawa, e mōhiotia ana ko te konumohe waikura i roto i te ahumahi, ā, koia te rauemi mata taketake mō te hanga konganuku konumohe; ka taea hoki te whakamahi i roto i te hanga o ngā pereki ātete-whakarewa, ngā ipu ātete-whakarewa, ngā ngongo ātete-whakarewa me ngā taputapu taiwhanga ātete-mahana teitei; ka taea hoki te whakamahi hei mea whakakoi, hei mea ārai-mura me te whakakī; ko te alumina kua whakapūkaratia parakore teitei te rauemi mata mō te hanga o te korundum horihori, te kōhatu matua whero horihori me te kōhatu matua kikorangi; ka whakamahia hoki mō te hanga papa papa mō ngā ara iahiko whakauru nui o ēnei rā. He iti te rerekētanga o te alumina me te alumina kua whakapūkaratia i roto i te tukanga whakaputa me ētahi atu āhuatanga, he rerekē hoki ngā wāhi ahumahi e tika ana, nō reira i te hoko hua i mua i te tuatahi ki te kimi i ngā wāhi motuhake o te whakamahinga.
