Qodobbada Muhiimka ah ee Saameeya Xasilloonida Dhoobada u Adkaata Xidhashada

Dhoobada Alumina waa nooc ka mid ah walxaha dhoobada ah oo leh alumina oo ah jirka ugu weyn. Dhoobada Alumina waxay leeyihiin gudbin wanaagsan, hanti farsamo, iska caabin xirasho iyo iska caabin heerkul sare, oo sidoo kale loo yaqaan dhoobo gaar ah. Walxaha dhoobada Al2O3 waa qaab-dhismeed lix geesood ah oo cufan oo ka kooban ion oksijiin, iyo ion aluminium ah oo lagu buuxiyay laba meelood meel farqiga octahedral, kaas oo la mid ah qaab-dhismeedka α-Al2O3 ee corundum ee dabiiciga ah ee deggan, sidaa darteed dhoobadu waxay leedahay bar dhalaal badan, adkaansho sare, waxay leedahay iska caabin xirasho oo aad u fiican. Adkeysiga dhoobada Alumina ≥HRA85, adkaanshaheedu waa kan labaad ee kaliya dheemanka, iska caabinta xirashadu waa mid aad u fiican.

Guud ahaan, aluminiumka dhoobada ah ee alumina waxaa loo qaybiyaa nooca caadiga ah iyo nooca daahirnimada sare. Nooca caadiga ah sida ku xusan nuxurka Al2O3 waxaa loo qaybiyaa 92% dhoobada alumina, 95% dhoobada alumina, 96% dhoobada alumina. Nooca saafiga ah ee sare waa 99% dhoobada alumina iyo ka sarreeya dhoobada, heerkulkeeda sintering wuxuu u sarreeyaa 1650-1990℃. 99.7%-99.9% saafinimada sare ee dhoobada alumina waxaa loo isticmaali karaa warshadaha elektaroonigga ah sida guddiga wareegga isku dhafan iyo walxaha dahaarka ee soo noqnoqda sare, warshadaha semiconductor ee wafers silicon shiidi, iwm., waa wafer silicon silicon wafer kiimikada nadiifinta farsamada ee qaybaha muhiimka ah ee taageerada iyo waxyaabaha la isticmaalo.

Inta badan ee alumina-da ee dhoobada iska caabisa xirashada, ayaa waxqabadka sii xasilloon, taas oo ah, inta badan ee aluminium-ka, ayaa ka sii wanaagsan waxqabadka iska caabiya xirashada. Dhoobada Alumina oo ah walxo dhoobo ah oo horumarsan, oo leh horumarinta degdegga ah ee agabyada cusub ee warshadaha u adkaysta xirashada, ayaa si aad ah loogu isticmaali doonaa bulshada casriga ah.

Chemshun Ceramics waxay bixisaa noocyo kala duwan oo ah dhoobada alumina saafi ah oo heer sare ah, sida: 92% Al2O3 & 95% Al2O3 lakabka dhoobada alumina ee caadiga ah ee u adkaysta xirashada, qaybaha dahaarka dhoobada iyo roogagga, lixgeesle/taayir dhoobo ah, tuubo dhoobo ah/tuubo/xusul, dhululubo dhoobo ah, baloog dhoobo ah/cube, leben dhoobo ah, 99.7% sagxadda salka alumina iyo saxanka dhalaalinta alumina, 99% dhoobada rasaasta u adkaysta alumina, iwm.
