Ibyiza no gutondekanya Ceramics ya Alumina

Alumina ceramic ni ubwoko bwa alumina (Al2O3) nkibikoresho nyamukuru byubutaka, bikoreshwa muri firime yibyibushye.Ububiko bwa Alumina bufite ubushobozi bwiza, imbaraga za mashini hamwe nubushyuhe bwo hejuru.

Ububiko bwa Alumina kuri ubu bugabanijwemo ubwoko bubiri: ubuziranenge bwinshi kandi busanzwe.Ceramic isukuye cyane alumina ceramic irenga 99,9% ya Al2O3 yibikoresho byubutaka, kubera ubushyuhe bwayo bugera kuri 1650-1990 ℃, uburebure bwumurambararo wa 1 ~ 6μm, mubisanzwe bikozwe mubirahure byashongeshejwe kugirango bisimbuze platine ikomeye.Kubera itumanaho ryayo no kurwanya ruswa ya alkali, irashobora gukoreshwa nkumuyoboro wamatara ya sodium, mu nganda za elegitoroniki irashobora kandi gukoreshwa nkumuzunguruko w’umuzunguruko hamwe nibikoresho byihuta cyane.

Ubukorikori busanzwe bwa alumina bugabanijemo ibice 99, farashi 95, farashi 90, farisari 85 nandi moko ukurikije ibikubiye muri Al2O3, rimwe na rimwe ibirimo Al2O3 muri 80% cyangwa 75% nabyo bifatwa nkibisanzwe bisanzwe bya alumina ceramic.Muri byo, ibikoresho 99 bya alumina ceramic bikoreshwa mu gukora ubushyuhe bwo hejuru cyane, umuyoboro w’itanura hamwe n’ibikoresho bidasanzwe birwanya kwambara, nk'ibikoresho byo mu bwoko bwa ceramic, kashe ya ceramic na valves y'amazi, n'ibindi. ibice;85 alumina ceramic material ikunze kuvangwa nigice cya talc, igateza imbere amashanyarazi nimbaraga za mashini, kandi irashobora gufungwa na molybdenum, niobium, tantalum nibindi byuma, bimwe bikoreshwa nkibikoresho byumuyagankuba.
