Gushyira ibicu bishyushye ninzira yo gucumura ceramic munsi yigitutu cyihariye. Iremera icyarimwe gushyushya hamwe no gushiraho igitutu cyamafumbire kugirango ikore ibikoresho bifite ingano nziza, ubucucike buri hejuru, hamwe nubukanishi bukomeye.

Igikorwa cyo gukanda gishyushye gikwiranye cyane cyane n’umusaruro w’ubushyuhe bwo hejuru cyane (UHTCs), ibyo bikaba ibikoresho bidakunze gucengera mu bucucike bukabije mu bikorwa bisanzwe byo gucumura.

Mu myaka yashize, abashakashatsi bagerageje uburyo butandukanye bwo gucumuraAlNno kongera ibiranga.AlNKugaragaza guhuza, bityo, kugirango ubone ubucucike bwuzuye, bigomba gucumurwa ku bushyuhe buri hejuru ya 1800 ℃. Gukanda bishyushye rero bikoreshwa mubikorwa byo gucumuraAlNutarinze gucumura.

Hot-press sintering nubuhanga busanzwe bukoreshwa mukuzamura imbaraga za ceramique ya AlN kubera ibi bintu byihariye. Ubwa mbere, gufashwa nigitutu cyogukorwa bikorwa bifatanije nuburyo bushyushye bwo gucumura kugirango bifashe mukurema ceramika yuzuye ya AlN yuzuye. Umuvuduko wo hanze utanga densification imbaraga zinyongera ugereranije no gucumura bidafite umuvuduko, kugabanya ubushyuhe bwa sinteri hafi 50-150 ℃ kandi bikagabanya imiterere yintete nini.

Amashanyarazi ashyushye ya aluminium nitride ceramic ikoreshwa munganda za semiconductor zisaba imbaraga zamashanyarazi zikomeye, imbaraga zidasanzwe hamwe nubushuhe buhebuje.
