Izitena zeCorundum/izitena zeCorundum Mullite
Ulwazi lweMveliso
Isitena seCorundumIimveliso ezichasene ne-corundum njengesigaba esiphambili sekristale, kunye nomxholo we-alumina odlula i-90%.
Udidi:Izitena zeCorundum zahlulwe ngokubanzi zibe zizitena zecorundum ezisinteziweyo kunye nezitena zecorundum ezisinteziweyo. Eyokuqala yenziwe nge-sintered alumina, ngelixa eyesibini yenziwe nge-fused corundum. Izitena zecorundum ezingatshayelwanga zinokwenziwa kusetyenziswa i-phosphoric acid okanye ezinye izibopheleli.
Iimpawu Zokusebenza:
Iimpawu Ezintle Zokurhawuzelela:Ubushushu obuthambileyo obungaphantsi komthwalo wezitena ze-corundum budlula i-1700°C, kwaye ezinye izitena ze-chrome corundum zinokufikelela kubushushu obudlula i-1790°C. Zihlala zizinzile kwiindawo ezinobushushu obuphezulu kwaye azichaphazeleki kukuguquka okanye kukonakala.
Amandla aphezulu:Amandla okucinezela ezitena ze-corundum ezicocekileyo kakhulu kubushushu begumbi ngokubanzi yi-70MPa-100MPa, ngelixa ezo zezitena ze-chrome corundum ezisebenza kakuhle zidlula i-150MPa kwaye zinokufikelela kwi-340MPa.
Uzinzo Olulungileyo Lweekhemikhali:Izitena zeCorundum ziyakwazi ukumelana kakhulu ne-asidi okanye i-alkaline slags, iintsimbi, kunye neglasi enyibilikisiweyo, kwaye azichaphazeleki ziikhemikhali.
Ukumelana okunamandla nokukhukuliseka kwenkunkuma:Umzekelo, umxholo weCr₂O₃ kwizitena ze-chrome corundum uthintela ngempumelelo i-slag enyibilikisiweyo ukuba ingangeni emzimbeni wezitena ngemingxunya ye-capillary, nto leyo ebangela ukuba ukukhukuliseka kwe-slag kube ngcono kwizitena ze-corundum eziqhelekileyo.
Izithako eziphambili kunye nezixhobo eziluhlaza:
Eyona nto iphambili kwizitena ze-corundum yi-alumina (Al₂O₃), edla ngokudlula i-90%, ezinye ziqulathe ukuya kuthi ga kwi-99%. Izinto ezisetyenzisiweyo ziquka i-sintered alumina kunye ne-fused corundum. Ezinye izinto zeminerali zingongezwa ukwenza izinto ezidityanisiweyo, ezifana ne-Cr₂O₃ kwizitena ze-chrome corundum kunye ne-ZrO₂ kwizitena ze-zirconium corundum.
Izitena zeCorundum-mulliteziitena ezidityanisiweyo ezichaseneyo ezakhiwe ngamanqanaba amabini azinzileyo obushushu obuphezulu: i-corundum (Al₂O₃) kunye ne-mullite (3Al₂O₃・2SiO₂). Zidibanisa amandla aphezulu e-corundum kunye nokumelana okuhle kakhulu nobushushu be-mullite, nto leyo ezenza zibe zizinto ezishushu kakhulu ezilinganisela ukusebenza kunye nokusebenza kakuhle kweendleko.
Izinto eziPhambili kunye neempawu zoLwakhiwo
Ulwakhiwo lweSigaba esiPhambili seCrystalline:I-Corundum kunye ne-mullite zii-crystal phases ezimbini eziphambili, apho umxholo we-alumina uqhele ukusuka kwi-70% ukuya kwi-90%, kwaye intsalela ikakhulu yi-silicon dioxide (SiO₂). Isiphumo sokusebenzisana kwezi zigaba zimbini silinganisa ukusebenza.
Ulwakhiwo oluncinci:Ii-Mullite phases zisasazwa phakathi kweenkozo ze-corundum ngendlela yeekristale ezimile okwenaliti okanye ezikwi-columnar, zenza isakhiwo "se-corundum skeleton + mullite connection". Oku akupheleli nje ekukhuliseni amandla ezitena kodwa kukwathintela uxinzelelo lobushushu ngokusebenzisa izikhewu ze-micro-crystal.
Iingenelo eziphambili zokusebenza
Ukumelana okugqwesileyo koxinzelelo lobushushu:Le yeyona nzuzo yayo iphambili. I-Mullite inomlinganiselo ophantsi wokwanda kobushushu, kwaye isakhiwo sayo sekristale esimile okwenaliti sitsala uxinzelelo olubangelwa kukuguquguquka kobushushu, kunciphisa kakhulu ukuqhekeka okubangelwa kukupholisa ngokukhawuleza kunye nokufudumeza kumaqondo obushushu aphezulu. Ukusebenza kwayo kudlula ukusebenza kwezitena ze-corundum ezicocekileyo.
Amandla alinganayo kunye nokumelana nokugqwala:Ubukho besigaba se-corundum buqinisekisa amandla aphezulu kwigumbi kunye namaqondo obushushu aphezulu, ngelixa bukwabonelela ngokumelana okuhle ne-asidi ye-slag, iglasi enyibilikisiweyo, kunye nezinye izinto. Nangona ukumelana kwayo ne-alkali kungaphantsi kancinci kunokwezitena ze-chrome corundum, inika uluhlu olubanzi lwezicelo.
Ukuqhuba kobushushu okuphakathi:Xa ithelekiswa nezitena ze-corundum ezinoxinano oluphezulu, inika ukuhanjiswa kobushushu obuphantsi ngelixa igcina inqanaba elithile lokufakelwa kobushushu, inciphisa ukulahleka kobushushu kwizixhobo zobushushu obuphezulu kwaye iyenza ifaneleke kwizicelo ezifuna ukufakwa kobushushu obuphezulu.
