Abstract
Bor bileşikleri ile
ilgili çalışmaların hızla çeşitlilik kazanması bu bileşiklerin endüstriyel
üretim koşullarının belirlenmesinin önemini daha da artırmaktadır. Bu bağlamda bu
çalışmada, kristalizasyon yöntemi kullanılarak lityum metaborat dihidrat
bileşiğinin 45 oC, 50 oC ve 60 oC
sıcaklıklarındaki üretim koşullarından biri olan kristal büyümesini etkileyen
difüzyon adımı ve çeşitli parametrelere bağlı olan difüzyon katsayısı
belirlenmiştir. Difüzyon katsayısının belirlenmesinde diyafram hücre
tekniğinden yararlanılmıştır. Ayrıca 45 0C deki difüzyon
katsayısının 50 0C de ve 60 0C dekine göre daha yüksek
olduğu belirlendi. Bundan dolayı 45 0C deki bu davranışı aydınlatmak
için farklı doygunluk sıcaklıklarındaki viskozite değerleri ölçülerek difüzyon
katsayıları bu eşitliğe göz önünde bulundurularak hesaplanmıştır.
