Ubudahangarwa n'ubushyuhe bwinshi, Ubucucike bw'umubiri bunini, Amazi make anyobwa, Ubushyuhe buto bwo kwaguka buvanze na coefficient fused spinel
Spinel ivanze ni igihingwa cya magnesia-alumina gifite isuku nyinshi, gikorwa binyuze mu guhuza magnesia na alumina mu itanura rya arc. Nyuma yo gukonjesha no gukonjesha, irashwanyaguzwa kandi igashyirwa mu byiciro ku buryo bukenewe. Ni kimwe mu bintu birwanya ubushyuhe bwinshi. Kubera ko ifite ubushyuhe buke, irangwa no kudahindagurika cyane mu bushyuhe no kudahindagurika, magnesia-alumina spinel ni ibikoresho fatizo birwanya ubushyuhe. Ifite ibara ryiza n'isura nziza, ubucucike bwinshi, kudahangana cyane no gukurwaho kw'amazi no kudahindagurika mu bushyuhe, bituma iki gicuruzwa gikoreshwa cyane mu itanura rizunguruka, igisenge cy'amatanura y'amashanyarazi, gushonga ibyuma n'ibyuma, itanura rizunguruka rya sima, itanura ry'ibirahure n'inganda zikora ibintu bitandukanye.

Ibice by'ubushyuhe byoroshye bikoreshwa mu gukora ibice byoroheje bikingira ubushyuhe
Alumina Bubble ikorwa binyuze mu guhuza alumina yihariye ifite isuku nyinshi. Ishonga ishyirwa mu mwuka ufunze ugana ku gice cy'ubuso. Irakomeye ariko irakonja cyane ugereranyije n'imbaraga z'umuvuduko wayo. Alumina Bubble ikoreshwa mu gukora ibintu byoroshye bikingira ubushyuhe aho amashanyarazi make n'ubushyuhe bwinshi ari byo bisabwa cyane. Ikoreshwa kandi neza ku bintu bigabanya ubushyuhe.

Udukoresho twa Mullite tumeze nk'urushinge dutanga ahantu hanini ho gushonga, ubushyuhe buke bushobora kwaguka kandi burwanya cyane ubushyuhe kuri Mullite ivanze
Fused Mullite ikorwa na Bayer process alumina n'umucanga wa quartz mwiza cyane mu gihe ivangwa mu itanura rinini cyane ry'amashanyarazi.
Ifite imiterere myinshi ya kristu zimeze nk'urushinge, zituma habaho gushonga cyane, ubushyuhe buke bushobora kwaguka kandi zirwanya cyane ubushyuhe, guhindagurika kw'imiterere y'ibintu, ndetse no kwangirika kw'ibinyabutabire ku bushyuhe bwinshi.

Ubukomezi bwiza bw'ibinyampeke bya Alumina y'umukara, ijyanye n'ibinyampeke n'ibinyabutabire
Alumina y'umukara ikorwa no gushonga kwa Calcined Bauxite mu itanura ry'amashanyarazi ku bushyuhe burenze 2000°C. Uburyo bwo gushonga buhoro buhoro bukurikira ivangavanga, kugira ngo haboneke kristu zifunganye. Gushonga bifasha mu gukuraho sulfure na karubone bisigaye, kugenzura neza urugero rwa Titania mu gihe cyo guhuza ibinyampeke bituma ibinyampeke bikomera neza.
Hanyuma ifu ikonje irasenywa, isukurwamo imyanda ya rukuruzi mu byuma bitandukanya rukuruzi bikomeye kandi bigashyirwa mu byiciro bito kugira ngo bijyane n'ikoreshwa rya nyuma. Imirongo yihariye ikora ibicuruzwa bikoreshwa mu buryo butandukanye.

Alumina Ultrafine ya Calcined yo gukora neza cyane, ishobora gukoreshwa mu bikoresho bya castable birimo silika fume n'ifu ya alumina ikora neza, kugira ngo igabanye kwiyongera kw'amazi, ipfundo ry'amazi no kongera imbaraga n'ubudahangarwa bw'amazi.
Alumina Ultrafine ya Calcined Ituma Ikora neza
Ifu ya alumina irimo calcium ikorwa hakoreshejwe calcium idasanzwe ya alumina cyangwa aluminium hydroxide ku bushyuhe bukwiye kugira ngo ihinduke crystallineα-alumina ihamye, hanyuma igasya ikavamo ifu nto. Ifu ya calcium ishobora gukoreshwa mu gatebo ka slide, mu mazuru, no mu matafari ya alumina. Byongeye kandi, ishobora gukoreshwa mu bikoresho bya castable bifite silika fume n'ifu ya alumina ikora, kugira ngo igabanye kwiyongera kw'amazi, porosity no kongera imbaraga n'ubugari.

Alumina ikora neza ifite ubuziranenge bwinshi, ingano nziza y'uduce duto kandi ikora neza cyane mu gusya
Alumina zikora neza zagenewe gukora ibintu bigabanya ubukana bw’ibice bito aho uburyo bwo gupakira uduce duto, rheology n’imiterere ihoraho yo gushyiramo ibintu ari ingenzi kimwe n’imiterere ihanitse y’umusaruro wa nyuma. Alumina zikora neza zishyirwa hasi kugeza ku kristu z’ibanze (imwe) hakoreshejwe uburyo bwo gusya bunoze cyane. Ingano mpuzandengo y’uduce duto, D50, ya alumina zikora neza cyane, bityo ingana hafi n’umurambararo wa kristu imwe. Guhuza alumina zikora neza n’ibindi bice bya matrix, nka alumina ya tabular 20μm cyangwa spinel 20μm, bituma kugenzura ingano y’uduce duto kugira ngo hagerwe ku ruhushya rw’ahantu hifuzwa.

Umupira wa Alumina Ceramic ni wo ukoreshwa mu gusya imipira, ibikoresho byo gusya mu nkono
Ibikoresho by'ingenzi bya Alumina Ceramic Ball ni alumina, ikorwa hakoreshejwe ikoranabuhanga ryo gukurura no gukanda umupira ukoresheje isostatic, ugashyirwa mu mupira ushyushye kuri dogere selisiyusi 1600. Ibiranga ni ibi bikurikira: ubucucike bwinshi, kwangirika guke, kudashira, kudashira, kudashira, kudashira neza kw'imitingito, kudashira neza kw'aside na alkali, kudahumanya ikirere, kunoza imikorere yo gusya, kugabanya ikiguzi cyo kuwukoresha.

Sintered Mullite na Fused Mullite bikoreshwa cyane cyane mu gukora Refractories no gucukura ibyuma na Titanium Alloys.
Sintered Mullite yatoranijwemo bauxite y’umwimerere yo mu rwego rwo hejuru, binyuze mu guhuza ibintu mu buryo butandukanye, ikaba ifite calcium ku bushyuhe burenze 1750°C. Irangwa n’ubucucike bwinshi, kudahindagurika mu bushyuhe, kudahinduka kw’ubushyuhe bwinshi ndetse no kudahinduka kw’ibinyabutabire n’ibindi.
Mullite, isanzwe idakunze kuboneka mu buryo karemano, ikorwa mu buryo bw'ubukorano kugira ngo ikoreshwe mu nganda binyuze mu gushongesha cyangwa gutwika aluminiyumu zitandukanye. Imiterere idasanzwe ya thermo-mechanical hamwe no kudahungabana kwa mullite ikorwamo bituma iba ingenzi mu bikorwa byinshi byo gushonga no gushushanya.
