Abstract
Bor oksitin endüstriyel üretimi, borik asidin 550-1000 C'de ergitilmesiyledir. Bilinen proseslerde camsi ergiyik katilasincaya kadar sogutulup, kirilir ve elenerek istenilen boyuta ve tane dagilimina getirilir. Borik asidin ergitilmesi, üretim prosesinin en kritik ve pahali kismidir. Çünkü ergimis bor oksit hem yüksek sicaklik ister, hem de firinin tuglalarina ve metal aksamina zarar verir. Bulusumuzda bor oksitin sanayi üretimi, ergitme ve yukarida bahsedilen diger kademeler olmadan gerçeklestirilmistir. Bu üretim yönteminde, borik asidin bor okside dönüsümü, titresimli akiskan yatakta, iki kademeli olarak önce metaborik aside dönüstürülmekte ve ikinci kademede 250 C'ye kadar isitilarak saglanmaktadir. Birinci kademede, önce metaborik asit yatagi olusturulmakta ve bu yatak içerisine borik asid sürekli beslenerek metaborik asit elde edilmektedir. Ikinci kademede de, yatakta olusturulmus olan boroksit üzerine akan metaborik asit'den bor oksit elde edilmektedir. Ergime (DEVAMI VAR)
