Guud ahaan, lebenka aluminiumka sare leh waa in aan loo isticmaalin foornada jawiga alkaline. Maadaama maaddada alkaline iyo acidic ay sidoo kale leeyihiin koloriin, waxay dhex geli doontaa lakabyada qoto dheer ee lebenka aluminiumka sare leh qaab isku-dhafan, taasoo sababi doonta in lebenka adkaysi u leh uu burburo.
Lebenka aluminiumka ee sareeya ka dib nabaad-guurka jawiga alkaline waa dildilaacyo jiif ah. Nabaad-guurku wuxuu ka kooban yahay gaasaska shidaalka ee cawlan, gaasaska gubanaya, iyo qaybaha alkaline ee alaabada kale. Qaybahani waxay la falgalaan wejiga galaaska iyo dhagaxa mulite ee lebenka aluminiumka ee sareeya.
Lebennada aluminiumka sare leh ee alkaline-ka mirdheeya ayaa ka soo muuqan doona dusha sare. Isku-dhafka gaaska gubanaya ayaa sidoo kale abuuri doona nitrate soo jiidanaya, oo ku milmaya farqiga lebennada aluminiumka sare leh; falcelinta barafka la sameeyay waxay samayn doontaa marxalad cusub oo adag. Marka nitriles-ka nasiibka leh ee aan biyaha lahayn ay la xiriiraan vagram-ka la soo saaray, falcelinta ka hortagga uumiga ayaa dhici doonta, taasoo keenta in lebenka aluminiumka sare uu jabo ama uu dhaco. Intaa waxaa dheer, daxalka kulaylka ayaa sidoo kale aad u daran daxalka lebenka ee aan adkaysan karin. Sababtoo ah nabaad-guurka Fang quartz, Skywine, iyo quartz crystal silica. Isticmaalka foornada dabka ayaa ka daran baastada qabow.
Waxyeellada lebenka ee silicon dioxide sidoo kale aad ayay u daran tahay. Silica waxaa lagu milmaa marxaladda lebenka aluminiumka sare leh. Nitrate-ka nasiibka leh ee dhalaalaya iyo dhagaxyada silikoonka ee dhibicda dhalaalaysa ee hooseeya waxay sameeyaan xaddi badan oo marxalad dareere ah. Inta badan ee silica ku jirta lebenka, ayaa sii badanaysa xaddiga marxaladda dareeraha ah. Marxaladaha dareeraha xad-dhaafka ah waxay waxyeellayn doonaan lebenka aluminiumka sare leh. Silikoonka Silicon sidoo kale waxaa waxyeellayn doona lebenka. Sababtoo ah silica xorta ah ayaa la isticmaalaa, marxaladda Mo Lai Shi way libdhi doontaa. Ka dib jawaabta nitrate-ka lickle iyo dhagaxa mullite waxay sababi kartaa ballaarin burbur ah oo ku timaadda lebenka aluminiumka sare leh.
Lebennada aluminiumka sare leh waxay leeyihiin iska caabin aad u fiican heerkulka sare iyo xoqidda. Waxaa si weyn loogu isticmaalaa dahaarka foornooyinka warshadaha kala duwan, sida foornooyinka qarxa, foornooyinka hawada kulul, iyo foornooyinka wareega. Si kastaba ha ahaatee, foornada warshadaha ee jawiga alkaline, isticmaalka lebennada aluminiumka sare leh waa xaddidan tahay.
Sifooyinka kiimikada ee lebenka alumina ee sare waxay ka dhigaan inay iska caabiyaan saameynta deegaannada aashitada leh. Si kastaba ha ahaatee, jawi aad u alkaline ah, sida foornada sibidhka ama foornada galaaska, lebenka alumina ee sare waxay la falgalaan oksaydhyada birta alkali, taasoo keenta in lebenku uu dillaaco oo uu burburo. Falcelinta u dhaxaysa lebenka Al2O3 iyo oksaydhyada birta alkali waxay badanaa keentaa sameynta jel alkali aluminosilicate ah, kaas oo leh dhibic dhalaalaysa oo si fudud uga gudbi karta dildilaaca.
Si loo xalliyo dhibaatadan, dhowr xeeladood ayaa la isticmaalay si loo hagaajiyo iska caabbinta lebenka aluminiumka sare leh ee deegaannada alkaline. Xalka keliya ayaa ah in lagu daro magnesia ama spinel lebenka alumina ee sare. Magnesia ama spinel waxay la falgalaan oksaydhka birta alkali si ay u sameeyaan marxalado spinel oo deggan, taas oo kor u qaadi karta iska caabbinta lebenka Al2O3 ee dildilaaca ay keento falcelinta alkali. Xal kale ayaa ah in lagu mariyo dahaar ilaalin ah dusha sare ee lebenka alumina ee sare si looga hortago taabashada tooska ah ee deegaanka alkaline.
Marka la soo koobo, lebenka aluminiumka sare leh wuxuu leeyahay ku habboonaan xaddidan jawiga alkaline ee dahaarka foornada warshadaha. Si kor loogu qaado iska caabbinta lebenka Al2O3 ee deegaannada alkaline, waxaa lagama maarmaan ah in lagu daro macdano ama dahaadh gaar ah si looga fogaado falcelinta waxyeelada leh ee oksaydhyada birta alkali. Waa muhiim in la doorto agabka saxda ah ee dahaarka foornada warshadaha si loo yareeyo khataraha iman kara loona badbaadiyo kharashyada.
