Applications Of Alumina In The Ceramic Industry


Aluminium oxide waa qaacidada kiimikada ee alumina, walax ka samaysan aluminium iyo ogsijiin. Waxaa si sax ah loogu yeeraa sida aluminium oxide waana tan ugu badan ee ka dhacda qaar ka mid ah aluminium oxides. Marka lagu daro in loo yaqaan alumina, waxa kale oo laga yaabaa inay raacdo magacyada aloxide, aloxite, ama alundum, iyadoo ku xidhan qaabkeeda iyo isticmaalkeeda. Maqaalkani wuxuu diiradda saarayaa codsiga aluminium ee beerta dhoobada.

 

Hubka

Qaar ka mid ah hubka jirka ayaa isticmaala taarikada dhoobada alumina, sida caadiga ah iyada oo la socota taageerada aramid ama UHMWPE, si loo helo waxtarka ka hortagga badi hanjabaadaha qoryaha. Si kastaba ha ahaatee, looma tixgeliyo inay tahay tayada milatari. Intaa waxaa dheer, waxay u adeegtaa si ay u xoojiso muraayadda aluminium ka dhanka ah saameynta .50 rasaasta BMG.


Codsiyada Biomedical

Qeybta biomedical-ka waxay si aad ah u isticmaashaa ceramics alumina sababtoo ah laqabsigooda sare ee noole iyo adkeysigooda xirashada iyo daxalka. Alumina ceramic waxay u adeegtaa sidii agabka galinta ilkaha, beddelka wadajirka ah, iyo qalabka kale ee caafimaadka.

 

Naaxsan

Alaabooyin badan oo naxaas ah ee warshaduhu waxay si joogta ah u isticmaalaan alumina sababtoo ah xooggeeda gaarka ah iyo qallafsanaanta. Marka la eego miisaanka Mohs ee adkaanta macdanta, qaabkeeda dabiiciga ah, corundum, waxa ay ku qiimaysaa 9—wax ka hooseeya dheeman. Si la mid ah dheeman, qofku wuxuu dahaaran karaa aluminium si looga hortago naaxinta. Sameeyayaasha iyo saacad-sameeyayaasha waxay isticmaalaan Diamantine, qaab budo ah (caddaan) ee ugu saafisan, sida xaaqid sare oo dhalaalaya.

Insulating

Alumina waa dahaarka heer sare ah, taas oo ka dhigaysa mid ku habboon in loo isticmaalo codsiyada heerkulka sare iyo kuwa tamarta sare leh. Waxa loo istcimaalay sidii substrate (silicon on sapphire) iyo tunnel xayndaab ku jira wareegyada isku dhafan si loo soo saaro aaladaha awooda sare leh sida transistor-ka-kaliya, aaladaha faragelinta quantum superconducting (SQUIDs), iyo qubits superconducting.

 

shiidid

Qaybta dhoobada sidoo kale waxay isticmaashaa alumina sida dhexdhexaad wax lagu shiidi karo. Alumina waa sheyga ugu fiican ee looga faa'iidaysto codsiyada shiididda sababtoo ah engegnaanteeda iyo xirashada caabbinta. Mashiinnada kubbadda, miraha gariiraya, iyo mashiinnada kale ee wax lagu shiidi karo waxay u isticmaalaan alumina sida dhexdhexaad wax lagu shiidi karo.

 

Gabagabo

Inkasta oo aluminium ay ugu horreyn caan ku tahay isticmaalka wax soo saarka aluminium, waxay sidoo kale muhiimad weyn ku leedahay meelo badan oo dhoobada ah. Waa shay ku habboon codsiyadan sababtoo ah barta dhalaalkeeda sare, kuleyl iyo qalab farsamo oo heer sare ah, sifooyin dahaaran, xirashada caabbinta, iyo biocompatibility.
