Alumiiniumoksiidipulber on paljude keraamiliste toodete lahutamatu osa. Seda kasutatakse plaatide valmistamiseks ja kulumiskindla keraamika valmistamiseks; lisaks on see katal\u00fcsaatorikandja. Alumiiniumoksiidi toodetakse alumiiniumh\u00fcdroksiidi ja vee segamisel ning kuumutamisel k\u00f5rgel temperatuuril. Kaltsineeritud alumiiniumoksiidi saab eristada nende kristallisuuruse ja naatriumisisalduse j\u00e4rgi. Madalama naatriumisisaldusega materjalid sobivad elektroonikarakendusteks v\u00f5i keraamiliste substraatide valmistamiseks.<\/p>\n
Tulekindlad keraamilised materjalid on anorgaanilised mittemetallid, millel on erakordne kuumakindlus ja mis sobivad ideaalselt t\u00f6\u00f6stuslike ahjude, katelde ja p\u00f5letusahjude jaoks. Nende soojusmahtuvust, soojusjuhtivust ja erosioonikindlusomadusi saab t\u00e4pselt kohandada. Neid kasutatakse muu hulgas ahjudes, kateldes ja p\u00f5letusahjudes; nende omadused muudavad nad mitmek\u00fclgseks materjaliks paljudes t\u00f6\u00f6stuslikes keskkondades, sealhulgas ahjudes, kateldes ja p\u00f5letusahjudes - sageli pakuvad nad t\u00f5husat kuumakindlust n\u00f5udlikes rakendustes, n\u00e4iteks ahjudes, kateldes v\u00f5i p\u00f5letusahjudes -, samas on nad vajadusel peenh\u00e4\u00e4lestatavad, et vastata konkreetsetele omadustele, nagu soojusmahtuvus, soojusjuhtivus v\u00f5i erosioonikindlus.<\/p>\n
pakume mitmesuguseid alumiiniumoksiidi pulbri katsetamise v\u00f5imalusi, alates teostatavusest kuni partiit\u00f6\u00f6tlemiseni. Insenerid saavad neid katseid kasutada, et h\u00e4\u00e4lestada koostisosi konkreetsete rakendusvajaduste jaoks ja hinnata keskkonnam\u00f5jusid; lisaks v\u00f5ivad nad m\u00e4\u00e4rata tulekindlate materjalide sobivuse konkreetsesse keskkonda s\u00f5ltuvalt sellistest teguritest nagu termilise \u0161oki vastupidavus, keemiline \u00fchilduvus sulametallide\/\u0161lakki kokkusobivus ja m\u00f5\u00f5tmete stabiilsus.<\/p>\n
Alumiiniumoksiid on t\u00e4nu oma keemilisele inertsusele ja poorsele struktuurile hindamatu v\u00e4\u00e4rtusega katal\u00fcsaatorikandja. See omadus v\u00f5imaldab tal aidata kaasa keemilistele reaktsioonidele naftakeemiat\u00f6\u00f6stuses ning tagada keskkonnakaitse. Poorset alumiiniumoksiidi saab valmistada h\u00fcdrotermilise s\u00fcnteesi teel, reageerides alumiiniumh\u00fcdroksiidi veega suletud anumas k\u00f5rgel r\u00f5hul ja temperatuuril, mille tulemuseks on \u00fclipuhtad nanosuuruses osakesed, mis vastavad kindlatele standarditele. Selle reaktsiooni tulemusel saadakse k\u00f5rge puhtusastmega alumiiniumoksiidi osakesi, mis vastavad t\u00e4psetele spetsifikaatidele ja suurustele. Sinteritud alumiiniumoksiidi osakesi saab seej\u00e4rel paagutada, et moodustada tihedat ja tugevat keraamikat, millel on mitmesugused t\u00f6\u00f6stuslikud rakendused.<\/p>\n
Alumiiniumoksiid on silmapaistev soojuse hajutamise materjal, millel on madal soojuspaisumise m\u00e4\u00e4r ja elektriisolaatori omadus, mis muudab selle kasulikuks elektroonikarakendustes. alumiiniumoksiidi pulber on t\u00f5hus soojuse hajutamise materjal, millel on k\u00f5rge soojusjuhtivus (30-36 W\/m - K), madal soojuspaisumise koefitsient, hea keemiline stabiilsus ja elektriisolatsiooniv\u00f5ime. Seda kasutatakse laialdaselt elektroonikaseadmetes, uutes energias\u00f5idukites, 5G-side ja muudes valdkondades.<\/p>\n
Alumiiniumoksiidi pulber on tavaliselt valge v\u00f5i valkjas v\u00e4rvusega ja sellel on kristalliline struktuur. Seda v\u00f5ib ka kuivpressida, isostaatiliselt pressida, kuumpressida, pressida, valada lindiga, pritsida ja segada mitmesuguste orgaaniliste v\u00f5i anorgaaniliste m\u00e4\u00e4rdeainete, plastifikaatorite v\u00f5i elektrol\u00fc\u00fctidega.<\/p>","protected":false},"excerpt":{"rendered":"
