Lityum Metaborat Dihidratın Difüzyon Katsayısının Belirlenmesi
Bor bileşikleri ile ilgili çalışmaların hızla çeşitlilik kazanması bu bileşiklerin endüstriyel üretim koşullarınınbelirlenmesinin önemini daha da artırmaktadır. Bu bağlamda bu çalışmada, kristalizasyon yöntemi kullanılaraklityum metaborat dihidrat bileşiğinin 45 oC, 50 oC ve 60 oC sıcaklıklarındaki üretim koşullarından biri olan kristalbüyümesini etkileyen difüzyon adımı ve çeşitli parametrelere bağlı olan difüzyon katsayısı belirlenmiştir.Difüzyon katsayısının belirlenmesinde diyafram hücre tekniğinden yararlanılmıştır. Ayrıca 45 0C deki difüzyonkatsayısının 50 0C de ve 60 0C dekine göre daha yüksek olduğu belirlendi. Bundan dolayı 45 0C deki bu davranışıaydınlatmak için farklı doygunluk sıcaklıklarındaki viskozite değerleri ölçülerek difüzyon katsayıları bu eşitliğegöz önünde bulundurularak hesaplanmıştır
Determination of Diffusion Coefficient of Lithium Metaborate Dihydrate
The rapid diversification of studies on boron compounds further increases the importance of these compounds in the industrial environment. Therefore, in this study, the diffusion step and diffusion coefficient of the lithium metaborate dihydrate compound at 45 oC, 50 oC and 60 oC temperatures were determined by crystallization method. The diaphragm cell technique was used to determine the diffusion coefficient. It was also found that the diffusion coefficient at 45 °C is higher than at 50 °C and 60 °C. Therefore, to investigate this behavior at 45 °C, the viscosity values at different saturation temperatures were measured and the diffusion coefficients were calculated considering this equality.
