Isitena esidityanisiweyo segalundum yeglasi yokunyibilikisa iziko
Isitena esimhlophe esidityanisiweyo se-corundum yi-α-AL2O3, eyinkqubo ye-trigonal crystal. Ifunyenwe ngokunyibilikisa i-alumina yemizi-mveliso kubushushu obuphezulu kwiziko lombane le-arc, ukupholisa kunye ne-crystallization kwii-ingots, emva koko kutyunyuzwe, kukhethwe, kulungiswe kwaye kuhlolwe. Yeyona izinzileyo phakathi kweendlela ezininzi zealumina. Inendawo yokunyibilika ephezulu (2030), uxinizelelo oluphezulu (3.99 ~ 4.0g / cm3), ubumbano lwentsebenzo, ukuqhuba kakuhle kwe-thermal, umlinganiso omncinci wokwanda kwe-thermal (86 × 10-7 /) kunye nomfaniswano. I-oxide ye-amphoteric, ihlala ine-alkaline engenamandla okanye ingathathi hlangothi kumaqondo aphezulu obushushu, kwaye inokuzinza okuhle kwemichiza. Ke ngoko, i-corundum emhlophe ehlanganisiweyo yinto enqabileyo yokuphosa utyalomali. Izinto ezihlanganisiweyo ezimhlophe ze-corundum zityebile kwimithombo yezimbiwa kwaye ngamaxabiso asezantsi, afanelekileyo ekukhetheni nasekukhuthazeni.
Izalathiso zomzimba kunye neekhemikhali zezitena ezihlanganisiweyo zekorundum kwiglasi yokunyibilikisa iziko:
