Amatafari ya Corundum/Amatafari ya Corundum Mullite
Amakuru ku bicuruzwa
Itafari rya Corundums ni ibicuruzwa birwanya imihindagurikire y'ikirere bifite korundum nk'icyiciro cy'ibanze cya kristali, kandi ingano ya alumina irenga 90%.
Ishyirwa mu byiciro:Amatafari ya Corundum ashyirwa mu byiciro by’ingenzi birimo amatafari ya corundum yasinywe n’amatafari ya corundum yasinywe. Iya mbere ikozwe muri alumina yasinywe, mu gihe iya nyuma ikozwe muri corundum yasinywe. Amatafari ya corundum adatwikwa ashobora no gukorwa hakoreshejwe aside fosforike cyangwa ibindi bikoresho.
Ibiranga Imikorere:
Imiterere myiza cyane yo gushyushya:Ubushyuhe bw'amatafari ya corundum bugabanuka munsi y'umutwaro burenga 1700°C, kandi amwe mu matafari ya chrome corundum ashobora kugera ku bushyuhe burenga 1790°C. Aguma ahamye mu bidukikije birimo ubushyuhe bwinshi kandi ntashobora kwangirika cyangwa kwangirika.
Ingufu nyinshi:Ingufu zo gukanda amatafari ya corundum afite ubuziranenge bwinshi ku bushyuhe bw'icyumba muri rusange ni 70MPa-100MPa, mu gihe amatafari ya chrome corundum afite ubuziranenge burenze 150MPa kandi ashobora kugera kuri 340MPa.
Ubudahangarwa bwiza bwa shimi:Amatafari ya Corundum arwanya cyane ibintu birimo aside cyangwa alkaline, ibyuma, n'ibirahure bishongeshejwe, kandi ntashobora kwangizwa n'ibinyabutabire.
Ubudahangarwa bukomeye ku isuri y'ibishishwa:Urugero, Cr₂O₃ irimo amatafari ya chrome corundum irinda neza ko amatafari yashongeshejwe yinjira mu mubiri w'amatafari anyuze mu mwenge w'imiyoboro y'amaraso, bigatuma amatafari asanzwe ya corundum adakomera cyane.
Ibikoresho by'ingenzi n'ibikoresho fatizo:
Igice cy'ingenzi cy'amatafari ya korundum ni alumina (Al₂O₃), ubusanzwe irenga 90%, amwe akaba arimo kugeza kuri 99%. Ibikoresho fatizo birimo alumina ivanze na corundum ivanze. Ibindi bikoresho by'amabuye y'agaciro nabyo bishobora kongerwamo kugira ngo bikore ibikoresho bivanze, nka Cr₂O₃ ku matafari ya chrome corundum na ZrO₂ ku matafari ya zirconium corundum.
Amatafari ya Corundum-mulliteni amatafari ahuza ibintu bivanze agizwe n'ibice bibiri bihindagurika mu bushyuhe bwinshi: corundum (Al₂O₃) na mullite (3Al₂O₃・2SiO₂). Ahuza imbaraga nyinshi za corundum n'ubushyuhe bwiza bwo kurwanya mullite, bigatuma aba ibikoresho bipima ubushyuhe bwinshi bihuza imikorere n'uburyo ihendutse bwo kugabanya ikiguzi.
Ibice by'ingenzi n'imiterere y'imiterere
Imiterere y'icyiciro cy'ingenzi cya kristu:Corundum na mullite ni ibice bibiri by'ingenzi bya kristu, aho alumina isanzwe iri hagati ya 70% na 90%, naho ibisigaye bigabanyirizwa cyane cyane silicon dioxide (SiO₂). Ingaruka z'ubufatanye bw'ibi bice byombi zipima imikorere.
Imiterere mito:Ibyiciro bya Mullite bikwirakwizwa hagati y’ibinyampeke bya corundum mu buryo bwa kristu zimeze nk'urushinge cyangwa kristu zimeze nk'inkingi, bigakora imiterere ya "corundum skeleton + mullite connection". Ibi ntibyongera imbaraga z'amatafari gusa ahubwo binarinda ubushyuhe bukabije binyuze mu cyuho gito cy'amakristale.
Ibyiza by'ingenzi mu mikorere
Ubudahangarwa budasanzwe bw'ihungabana ry'ubushyuhe:Iyi ni yo nyungu yayo y'ingenzi. Mullite ifite ubushobozi buke bwo kwaguka k'ubushyuhe, kandi imiterere yayo isa n'urushinge rw'ikirahure igabanya umuvuduko uterwa n'ihindagurika ry'ubushyuhe, bigabanya cyane gucika kw'ubukonje n'ubushyuhe ku bushyuhe bwinshi. Imikorere yayo iruta iyamatafari ya corundum.
Ingufu ziringaniye no kurwanya ingese:Kuba hariho igice cya corundum bitanga imbaraga nyinshi haba mu bushyuhe bwo mu cyumba no mu bushyuhe bwinshi, ariko kandi binatanga ubudahangarwa bwiza ku bintu bivanze n’aside, ibirahure bishongeshejwe, n’ibindi bikoresho. Nubwo ubudahangarwa bwayo bwa alkali buri hasi gato ugereranyije n’amatafari ya chrome corundum, itanga uburyo bwinshi bwo kuyikoresha.
Ubushobozi buringaniye bwo gutwara ubushyuhe:Ugereranyije n'amatafari ya corundum afite ubucucike bwinshi, itanga ubushobozi bwo gutwara ubushyuhe buke mu gihe igumana urwego runaka rwo gukingira ubushyuhe, ikagabanya ubushyuhe butakaza mu bikoresho bikoresha ubushyuhe bwinshi kandi bigatuma ikoreshwa mu gukenera gukingira ubushyuhe.
