Alumina bụ ihe nkịtị inorganic na-abụghị ọla, nke a na-ejikarị eme ihe na ụlọ ọrụ, ihe owuwu, ngwá electronic, ọgwụ na mpaghara ndị ọzọ.

Okwu Mmalite Alumina

Alumina bụ ntụ ntụ na-acha ọcha ma ọ bụ na-acha ọcha nke nwere usoro ihe omimi nke Al2O3 na ịdị arọ nke 101.96.Ọ bụ ihe mejupụtara nke aluminom na oxygen, nke nwere nnukwu agbaze na ike.Alumina bụ ihe dị mkpa nke ụlọ ọrụ mmepụta ihe, nke a na-ejikarị eme ihe na ceramik, iko, ngwá electronic, ọgwụ na ubi ndị ọzọ.

Njirimara anụ ahụ nke alumina

Njirimara anụ ahụ nke alumina na-agụnye njupụta, isi ike, nkwụsi ike nke okpomọkụ, ngwa anya na ihe ndị ọzọ.Njupụta nke alumina bụ 3.9-4.0g / cm3, ike siri ike bụ Mohs hardness 9, nkwụsi ike nke okpomọkụ dị elu, ebe agbaze bụ 2054 ℃.Tụkwasị na nke ahụ, alumina nwekwara ezigbo ihe anya na ọ bụ ihe dị mkpa ngwa anya.

Chemical Njirimara nke alumina

The chemical Njirimara nke alumina tumadi gụnyere mmeghachi omume arụmọrụ dị iche iche chemical bekee, acid na alkali.Alumina na-emeghachi omume na acid iji mepụta nnu na mmiri aluminom, yana alkali na-emepụta aluminum hydroxide na mmiri.N'otu oge ahụ, alumina nwekwara njirimara nke acidic oxides, nke nwere ike imeghachi omume na ọtụtụ kemịkalụ.

Usoro nkwadebe nke alumina

Ụzọ nkwadebe bụ isi nke alumina bụ usoro kemịkalụ, usoro anụ ahụ na ihe ndị ọzọ.Usoro kemịkalụ bụ tumadi site na mmeghachi omume neutralization nke nnu aluminom na hydroxide iji nweta aluminum hydroxide, wee site na ọkụ ọkụ dị elu iji nweta aluminum oxide.Usoro anụ ahụ bụ tumadi site na ire ere, distillation, crystallization na usoro ndị ọzọ iji nweta alumina.

Alumina ngwa ubi

A na-eji alumina eme ihe n'ọtụtụ ebe na ụlọ ọrụ, ihe owuwu, ngwá electronic, ọgwụ na mpaghara ndị ọzọ.N'ime ụlọ ọrụ mmepụta ihe, a na-eji alumina eme ihe na-emepụta ceramics, iko, mkpuchi na ihe ndị ọzọ.Na mpaghara ihe owuwu, a na-eji alumina na-emepụta ọnụ ụzọ, Windows, mgbidi ákwà mgbochi na ihe ndị ọzọ.N'ebe a na-emepụta ngwá electronic, a na-eji alumina eme ihe na-emepụta mbadamba sekit, ihe ndị na-emepụta ihe eletrik, wdg.

Atụmanya mmepe nke alumina

Site na mmepe sayensị na teknụzụ na-aga n'ihu, mpaghara ngwa nke alumina na-abawanye ụba.N'ọdịnihu, na mmepe ngwa ngwa nke ihe ọhụrụ, ike ọhụrụ na ubi ndị ọzọ, ọchịchọ maka alumina ga-anọgide na-abawanye.N'otu oge ahụ, na ọganihu na-aga n'ihu nke ihe nchebe gburugburu ebe obibi chọrọ, nkà na ụzụ mmepụta nke alumina ga-aga n'ihu na-eme ka ọ dịkwuo mma, na ndị ọzọ enyi na enyi na gburugburu ebe obibi, ịrụ ọrụ nke ọma na ike-azọpụta ụzọ mmepụta ga-aghọ usoro mmepe.

Alumina bụ ihe dị mkpa inorganic na-abụghị ọla, nke nwere ọtụtụ ihe eji eme ihe na uru akụ na ụba dị mkpa.N'ọdịnihu, na mmepe ngwa ngwa nke ihe ọhụrụ na ike ọhụrụ na mpaghara ndị ọzọ, ọchịchọ nke alumina ga-anọgide na-abawanye, ebe mmepụta nkà na ụzụ nke alumina ga-anọgide na-emeziwanye, ma na-enye onyinye dị ukwuu na mmepe nke ụmụ mmadụ.
