Aluminium oxide ndiyo kemikari formula yealuminium, chinhu chakagadzirwa nealuminium uye oksijeni. Inonyatso kunzi aluminium oxide uye ndiyo inonyanya kuitika kune mamwe aruminiyamu oxides. Pamusoro pekuzivikanwa sealuminium, inogona zvakare kuenda nemazita aloxide, aloxite, kana alundum, zvichienderana nechimiro uye mashandisiro ayo. Ichi chinyorwa chinotarisana nekushandiswa kwealumina mumunda weceramic.
Hondo
Zvimwe zvombo zvemuviri zvinoshandisa alumina ceramic plates, kazhinji yakabatana nearamid kana UHMWPE inotsigirwa, kuti iwane hunyanzvi hwekurwisa kutyisidzira kwepfuti. Zvisinei, haifungidzirwe seyemhando yehondo. Pamusoro pezvo, inoshanda kusimbisa girazi realuminium kurwisa .50 BMG mabara.
Biomedical Applications
Iyo biomedical sector inoshandisa zvakanyanya alumina ceramics nekuda kwehukuru hwavo biocompatibility uye kusimba kubva pakupfeka uye ngura. Alumina ceramic inoshanda sechinhu chekudyara mazino, majoini ekutsiva, uye zvimwe midziyo yekurapa.
Abrasive
Mazhinji maindasitiri abrasive zvinhu zvinowanzo shandisa alumina nekuda kwesimba rayo rakasiyana uye kuoma kwayo. Pachiyero cheMohs chekuoma kwemaminerari, chimiro chayo chinongoitika, corundum, chiyero che9-pazasi pedhaimani. Zvakafanana nemadhaimani, munhu anogona kupfeka alumina kudzivirira abrasion. Vagadziri vewachi nevagadziri vewachi vanoshandisa Diamantine, muchimiro chayo chehupfu (chena) chepamusoro, semushonga wepamusoro wekuporisha.
Insulating
Alumina ndeye yakanakisa insulator, ichiita kuti ive yakakodzera kushandiswa mukupisa-tembiricha uye yakakwirira-voltage application. Inoshandiswa senge substrate (silicon pasafire) uye mugero wemugero mumasekete akabatanidzwa kugadzira superconducting zvishandiso senge single-electron transistors, superconducting quantum interference devices (SQUIDs), uye superconducting qubits.
Kukuya
Iyo ceramics sector inoshandisawo alumina senge yekukuya. Alumina ndiyo yakakwana zvinhu zvekushandisa mukukuya zvikumbiro nekuda kwekuoma kwayo uye nekupfeka kuramba. Zvigayo zvebhora, zvigayo zvinozunguzika, uye mimwe michina yekukuya inoshandisa alumina senzira yekukuya.
Mhedziso
Kunyangwe alumina ichinyanya kuzivikanwa nekushandiswa kwayo mukugadzirwa kwealuminium, zvakare ine kukosha kwakakosha muminda yakawanda yeceramic. Icho chinhu chakanakira zvikumbiro izvi nekuda kweiyo yakakwirira kunyungudika nzvimbo, yakasarudzika yekupisa uye michina zvivakwa, insulating zvivakwa, kupfeka kuramba, uye biocompatibility.
