Alpha-alumina waxay leedahay sifooyin kiimiko oo deggan, iska caabin daxalka, qallafsanaanta sare, guryaha dahaarka wanaagsan, barta dhalaalka sare iyo adkaanta sare, waxaana loo isticmaalaa meelo kala duwan.
Codsiga budada α-alumina ee dhoobada
Ceramics Microcrystalline alumina waa nooc cusub oo walxo dhoobo ah oo leh lebis iyo qaab dhismeed cufan iyo nano ama cabbir hoosaadyo yar yar oo hadhuudh ah.Waxay leedahay faa'iidooyinka xoogga farsamada sare, xirashada caabbinta, caabbinta daxalka, caabbinta oksaydhka, isku-dhafka ballaarinta la hagaajin karo iyo xasilloonida kuleylka wanaagsan.Muuqaalkeeda ugu muhiimsan waa in crystal-ka aasaasiga ah uu yar yahay.Sidaa darteed, xaaladda ugu muhiimsan ee farsamada ee diyaarinta dhoobada alumina ee microcrystalline waa in la diyaariyo budada α-Al2O3 oo leh kareem yar oo asal ah oo asal ah iyo waxqabadyo sare oo sarreeya.Budada α-Al2O3 waxay noqon kartaa jidh dhoobo cufan oo heerkul hoose ah.
Codsiga budada α-alumina ee walxaha refractory
α-Al2O3 budada waxay ku kala duwan tahay qalabka dib-u-celinta marka loo eego codsiga, shuruudaha budada ayaa sidoo kale ka duwan.Tusaale ahaan, haddii aad rabto in aad dedejiso cufnaanta alaabta refractory, nano-alumina waa doorashada ugu fiican;Haddii aad rabto inaad diyaariso refractories qaabaysan, waxaad u baahan tahay budada α-Al2O3 oo leh miro aan fiicneyn, yarayn yar, iyo iska caabin qallafsan oo xooggan.crystallites Flake ama saxan-qaabeeya ayaa ka fiican;laakiin haddii ay tahay maaddada refractory amorphous, α-Al2O3 ayaa looga baahan yahay inuu yeesho dareere wanaagsan, firfircoonida sare ee dhaqdhaqaaqa, iyo qaybinta cabbirka qaybinta waxay u baahan tahay cufnaanta ugu weyn, iyo crystallites-ka-fiican ayaa ka fiican.
Codsiga budada α-alumina ee alaabada dhalaalaysa
Codsiyada qurxinta kala duwan waxay u baahan yihiin qalab kala duwan.Alaabooyinka loogu talagalay dhalaalid qallafsan iyo dhalaalid dhexdhexaad ah waxay u baahan yihiin xoog goynta xooggan iyo adkaanta sare, sidaa darteed qaab-dhismeedkooda yar-yar iyo kiristaalo ayaa looga baahan yahay inay noqdaan kuwo qalafsan;α-alumina budada ah ee si fiican u dhalaalaysa waxay u baahan tahay in alaabta la sifeeyay ay leedahay qallafsanaan hoose iyo dhalaal sare Sidaa darteed, yar yar ee crystal aasaasiga ah ee α-Al2O3, ka wanaagsan.
Codsiga budada α-alumina ee walxaha buuxinta
Maaddada buuxinta, si loo hubiyo in ay si fiican isugu darsamaan walxaha organic iyo in la yareeyo saamaynta viscosity ee nidaamka, shuruudaha aasaasiga ah ee α-Al2O3 waa in dheecaanku uu ku filan yahay, doorbidayo spherical, sababtoo ah sare sphericity, oogada.Inta yar ee tamarta, ayaa ka sii wanaagsan dheecaanka dusha sare ee kubbadda;Marka labaad, budada α-Al2O3 oo leh korriin dhammaystiran oo crystal ah, nadiifin kiimiko oo sarreeya iyo cuf-isjiid gaar ah oo run ah ayaa leh hab-kuleyl wanaagsan oo saameyn wanaagsan leh marka loo isticmaalo qalabka kuleylka iyo kuleylka.
Codsiga budada α-alumina ee maaddada capacitor corundum
Warshadaha, budada α-alumina saafiga ah ayaa inta badan lagu dhex miiro foorno koronto oo heerkulkeedu sarreeyo si loo sameeyo corundum macmal ah, oo sidoo kale loo yaqaan corundum fused.Qalabkani wuxuu leeyahay sifooyin adag oo sarreeya, geeso cad iyo geeso, iyo qaab-dhismeedka yar yar ayaa doorbidaya meel u dhow.Inta lagu jiro habka xawliga sare leh, miraha xoqan waxay leeyihiin xoog goyn oo xooggan, iyo miraha xoqan ma fududa in la jebiyo. sidaas darteed kordhinta nolosha adeegga.
