Habka diyaarinta eeyttrium oxidebudo
Habka roobabka wejiga ayaa inta badan loo isticmaalaa in lagu diyaariyo oksaydhyada dhulka dhifka ah, kuwaas oo inta badan ay ku jiraan habka roobka oxalate, habka roobka ammonium bicarbonate, habka urea hydrolysis iyo habka roobabka ammonia. Intaa waxaa dheer, granulation buufin sidoo kale waa habka diyaarinta kaas oo si weyn looga welwelay hadda. Habka roobka milixda
1. Habka roobka oxalate
Theoksaydh dhulka naadir ahoo ay diyaarisay habka roobka oxalate waxay leedahay faa'iidooyinka shahaadada crystallization sare, qaabka crystal wanaagsan, xawaaraha sifeynta degdega ah, content wasakh hoose iyo hawl fudud, taas oo ah habka caadiga ah ee diyaarinta nadiif sare.oksaydh dhulka naadir ahwax soo saarka warshadaha.
Habka roobabka ammonium bicarbonate
2. Habka roobka ee ammonium bicarbonate
Ammonium bikarbonateet waa dabeylo raqiis ah. Waagii hore, dadku waxay isticmaali jireen habka roobka ee ammonium bicarbonate si ay ugu diyaariyaan karbohaydraytyo naadir ah oo isku qasan oo ka soo baxa dareeraha macdanta dhulka naadirka ah. Waqtigan xaadirka ah, oksaydhyada dhulka dhifka ah waxaa lagu diyaariyaa habka roobabka ammonium bicarbonate ee warshadaha. Guud ahaan, habka roobabka ammonium bicarbonate waa in lagu daro ammonium bicarbonate adag ama xal chloride dhulka dhif ah heerkul gaar ah, ka dib gabowga, dhaqidda, qalajinta iyo gubashada, oksaydhka waa la helaa. Si kastaba ha noqotee, iyada oo ay ugu wacan tahay tirada badan ee xumbooyinka la soo saaro inta lagu jiro roobabka ammonium bicarbonate iyo qiimaha pH ee aan degganayn inta lagu jiro falcelinta roobabka, heerka nukleusku waa mid degdeg ah ama gaabis ah, taas oo aan ku habboonayn koritaanka crystal. Si loo helo oksaydhka leh cabbirka walxaha ku habboon iyo qaab-dhismeedka, xaaladaha falcelinta waa in si adag loo xakameeyaa.
3. Roobka Urea
Habka roobabka Urea ayaa si weyn loogu isticmaalaa diyaarinta oxide-ka naadirka ah, kaas oo aan kaliya ahayn mid raqiis ah oo sahlan in lagu shaqeeyo, laakiin sidoo kale awood u leh in lagu guuleysto xakamaynta saxda ah ee nukleation-ka hore iyo korriinka walxaha, sidaas awgeed habka roobabka urea ayaa soo jiitay dad aad iyo aad u badan. eex oo soo jiitay fiirsi iyo cilmi baadhisyo culimo badan wakhtigan.
4. buufin granulation
Tignoolajiyada granulation spray waxay leedahay faa'iidooyinka otomatiga sare, wax soo saarka sare ee wax soo saarka iyo tayada sare ee budada cagaaran, sidaas darteed buufinta buufinta ayaa noqotay habka granulation budada caadiga ah loo isticmaalo.
Sanadihii la soo dhaafay, isticmaalka eedhul dhif ahGoobaha dhaqameedku asal ahaan ismay beddelin, laakiin codsigeeda agabka cusub ayaa si cad u kordhay. Sida qalab cusub,naano Y2O3wuxuu leeyahay goob codsi oo ballaadhan. Maalmahan, waxaa jira habab badan oo lagu diyaariyo nano Y2O3walxaha, kuwaas oo loo qaybin karaa saddex qaybood: habka dareeraha, habka wajiga gaaska iyo habka wejiga adag, oo ka mid ah habka wejiga dareeraha waa inta badan la isticmaalo.Waxay u qaybsan yihiin buufinta pyrolysis, synthesis hydrothermal, microemulsion, sol-gel, gubasho. isku-dhafka iyo roobabka. Si kastaba ha ahaatee, spheroidizedyttrium oxide nanoparticleswaxay yeelan doontaa meel sare oo gaar ah oo gaar ah, tamarta dusha sare, dareere fiican iyo kala firdhisanaan, taas oo mudan in diirada la saaro.
