Crucibles ni ibintu by'ingenzi bigize ibikoresho bya shimi kandi ikora nk'ibikoresho byo gushonga no gutunganya amazi y'ibyuma, ndetse no gushyushya no gukora ibintu bivanze n'amazi. Bakora umusingi wo kwemeza neza imiti.
Umusaraba urashobora kugabanywamo ibyiciro bitatu byingenzi:ibishushanyo mbonera, ibumba ry'ibumba, hamwe n'ibyuma byo kubambwa.
Graphite crucibles ikorwa cyane cyane muri grafitiki ya kristaline, igumana ibintu bitandukanye byumubiri nubumara bya grafite. Bafite ubushyuhe bwiza bwo guhangana nubushyuhe bwo hejuru. Mugihe cyo gukoresha ubushyuhe bwinshi, bagaragaza coefficient zo kwagura ubushyuhe buke, bigatuma barwanya ubushyuhe bwihuse no gukonja. Graphite crucibles ifite imbaraga zo kurwanya ruswa irwanya aside na alkaline kandi byerekana imiti ihamye.
Bitewe nibi bintu biranga ibintu, umusaraba wa grafite ukoreshwa cyane mu nganda nka metallurgie, casting, imashini, n’ubuhanga bw’imiti. Basanga ikoreshwa ryinshi mugushongesha ibyuma byifashishwa hamwe no gushonga ibyuma bidafite fer hamwe na alloys, bitanga inyungu zikoranabuhanga nubukungu.
Silicon Carbide Crucibles:
Silicon carbide crucibles ni ibikoresho bikozwe mubutaka. Iyo ibinini bigomba gushyuha mubushyuhe bwinshi, birakenewe kubambwa kuko bishobora kwihanganira ubushyuhe bwinshi ugereranije nibirahure. Ubusanzwe Crucibles ntabwo yuzuzwa mubushobozi mugihe cyo kuyikoresha kugirango ibuze ibintu bishyushye kumeneka hejuru, bituma umwuka winjira mubwisanzure kandi byorohereza okiside. Bitewe nurufatiro ruto, umusaraba usanzwe ushyirwa kuri mpandeshatu yibumba kugirango ushushe neza. Bashobora guhagarikwa neza cyangwa ku mpande eshatu z'icyuma, bitewe n'ibisabwa mu bushakashatsi. Nyuma yo gushyushya, umusaraba ntugomba guhita ushyirwa hejuru yicyuma gikonje kugirango wirinde gukonja vuba no kuvunika. Mu buryo nk'ubwo, ntibigomba gushyirwa hejuru yimbaho kugirango birinde inkongi y'umuriro cyangwa inkongi y'umuriro. Uburyo bwiza ni ukwemerera umusaraba gukonja bisanzwe kuri trapo yicyuma cyangwa ukabishyira kuri net ya asibesitosi kugirango ukonje buhoro buhoro. Imigozi ifatika igomba gukoreshwa mugukemura.
Umusaraba wa platine:
Ibibumbano bya platine, bikozwe mu cyuma cya platine, bikora nk'ibice byabigenewe byo gusesengura amashyanyarazi atandukanye kandi bikoreshwa mu gushyushya ibikoresho bitari ibyuma, nko gukora fibre fibre no gushushanya ibirahure.
Ntibagomba guhura nabo:
Ibikoresho bikomeye nka K2O, Na2O, KNO3, NaNO3, KCN, NaCN, Na2O2, Ba (OH) 2, LiOH, nibindi.
Aqua regia, ibisubizo bya halogene, cyangwa ibisubizo bishoboye kubyara halogene.
Ibicuruzwa byibyuma bigabanuka byoroshye nibyuma ubwabyo.
Carbone irimo silikate, fosifore, arsenic, sulfure, hamwe nibindi bintu.
Nickel Crucibles:
Ahantu ho gushonga kwa nikel ni dogere selisiyusi 1455, kandi ubushyuhe bwikitegererezo muri nikel ikomeye ntibugomba kurenga dogere selisiyusi 700 kugirango wirinde okiside kubushyuhe bwinshi.
Kubambwa kwa Nickel birwanya cyane ibintu bya alkaline na ruswa, bigatuma bikenerwa no gushonga ibyuma, ibishishwa, ibumba, ibikoresho bivunika, nibindi byinshi. Nickel umusaraba uhujwe na alkaline flux nka NaOH, Na2O2, NaCO3, hamwe nibirimo KNO3, ariko ntibigomba gukoreshwa na KHSO4, NaHSO4, K2S2O7, cyangwa Na2S2O7 na sulfide itemba hamwe na sulfure. Gushonga umunyu wa aluminium, zinc, isasu, amabati, na mercure birashobora gutuma nikel ibamba. Imisaraba ya Nickel ntigomba gukoreshwa mu gutwika imvura, na borax ntigomba gushonga muri yo.
Nickel umusaraba akenshi urimo urugero rwa chromium, bityo rero ugomba kwitonda mugihe, isomo ryahagaritswe.
