Kule ngxaki siza kuqhubeka nokwazisa udidi lwezitena zomlilo ezigqumayo ezikhaphukhaphu kwii-oven zeglasi.
3. Udongweisitena somlilo esikhaphukhaphu esilulaYimveliso ethintela ukugquma eyenziwe ngodongwe oluthintela ukugquma olunomxholo we-Al2O3 ongama-30% ~ 48%. Inkqubo yayo yemveliso isebenzisa indlela yokongeza ukutsha kunye nendlela ye-foam. Izitena zomlilo ezithintela ukugquma ezilula zodongwe zineendlela ezahlukeneyo zokusetyenziswa, ezisetyenziswa kakhulu njengezinto ezithintela ukugquma zeeleya zokugquma kwii-oven ezahlukeneyo zoshishino apho zingadibani nezinto ezinyibilikisiweyo. Ubushushu bayo obusebenzayo yi-1200 ~ 1400 ℃.
4. Izitena zokuthintela ukufudumeza i-aluminium oxide. Le mveliso inokumelana nomlilo okuphezulu kunye nokumelana okuhle nokutshiswa kobushushu, kwaye isetyenziswa rhoqo njengomaleko wokuthintela ukufudumeza obushushu obuphezulu kwii-oven. Ubushushu bayo obusebenzayo yi-1350-1500 ℃, kwaye ubushushu bokusebenza beemveliso ezicocekileyo bunokufikelela kwi-1650-1800 ℃. Ziimveliso zokuthintela ukufudumeza ezinganyangekiyo ezenziwe ngezinto ezikrwada ze-fused corundum, i-sintered alumina, kunye ne-industrial alumina.
5. Izitena ze-mullite ezikhaphukhaphu. Ubushushu obuphezulu kunye neemveliso ezinganyangekiyo ezenziwe nge-mullite njengezinto eziphambili ezisetyenziswayo. Izitena ze-mullite zobushushu obuphezulu zinokumelana nobushushu obuphezulu, amandla aphezulu, ubushushu obuphantsi, kwaye zinokudibana ngqo namalangatye, kwaye zifanelekile kwiilayini zee-oven ezahlukeneyo zoshishino.
6. Izitena zebhola ezingenamiqolo ze-aluminium oxide. Izitena zebhola ezingenamiqolo ze-aluminium oxide zisetyenziselwa ukusetyenziswa ixesha elide ngaphantsi kwe-1800 ℃. Zinozinzo oluhle lweekhemikhali kunye nokumelana nokugqwala kumaqondo obushushu aphezulu. Xa kuthelekiswa nezinye izitena zokufakelwa ezikhaphukhaphu, izitena zebhola ezingenamiqolo ze-alumina zinobushushu obuphezulu bokusebenza, amandla aphezulu, kunye nokuqhuba kobushushu obuphantsi. Uxinano lwayo luphantsi ngama-50% ~ 60% kuneemveliso ezixineneyo ezichaseneyo zomxube ofanayo, kwaye zinokumelana nefuthe lomlilo oshushu kakhulu.
