Abstract

In this study, the optimum synthesis conditions for barium metaborate were investigated. The synthesis was conducted with the reaction of aqueous solutions of barium chloride dehydrate and sodium metaborate tetrahydrate. The reaction temperature, NaBO2/BaCl2 mole ratio, stirring rate and time, settling time, pH modifier type and concentration, the effects of second solvent and calcination were studied. The characterizations of the obtained crystals were done with the help of a XRD, SEM, TG-DTA and particle size analysis. The highest yield value for barium metaborate synthesis was found to be 88%. The best conditions of the barium metaborate synthesis were found to be 80 °C, stirring rate of 400 rpm, stirring time of 60 minutes and settling time of 60 minutes

Özet

Bu çalışmada baryum metaborat üretimi için gerekli optimum şartlar belirlenmeye çalışılmıştır. Üretim, baryum klorür dihidrat (BaCl2.2H2O) ve sodyum metaborat tetrahidrat (NaBO2.4H2O)’ın sulu ortamdaki reaksiyonu ile gerçekleştirilmiştir. Üretim için en uygun sıcaklık, NaBO2/BaCl2 oranı, karıştırma hızı, karıştırma zamanı, dinlendirme zamanı, çözücü tipi ve derişimi, etil alkol etkisi gibi parametreler incelenmiştir. Elde edilen kristallerinin karakterizasyonu, X-ışını kırınımı (XRD), taramalı elektron mikroskobu (SEM) ve partikül boyut ölçüm cihazları yardımıyla yapılmıştır. Kristallerin yapı suyu içerikleri ise TG-DTA analizleri ile belirlenmiştir. Baryum metaborat sentezi için en yüksek verim değeri %88 olarak bulunmuştur. Sentez açısından en uygun şartlar ise; reaksiyon sıcaklığı 80 oC, 400 rpm karıştırma hızı, 60 dk karıştırma ve 60 dk dinlendirme zamanı olarak tespit edilmiştir.
