Abstract

In this study grain growth kinetics of the TiO2-BaO-SiO2 based ceramics produced from BaCO3, TiO2and SiO2 ceramic powders has been investigated depending on sintering temperature and time. For this purpose, the different powder mixtures were prepared by ball milling technique in deionised water using ZrO2 balls for 20 h. The powders were calcined at 1000°C for 2 h after drying process. Produced powders was mixed 5% polyvinyl alcohol (PVA) and pressed as green body. The samples were sintered at 1175, 1200 and 1225°C for 1-4 h. Atomic force microscope (AFM) images were used for examinations of grain structure and size of the sintered specimens. Grain growth kinetic equation Gn=K.t.exp(-Q/RT) was used for determining of the activation energy of the produced ceramic materials. X-ray diffraction analysis (XRD) showed that the main phases formed in structure were BaTiO3 and Ba2TiSi2O8. © Afyon Kocatepe Üniversitesi

Özet

Çalışmada BaCO3, TiO2 ve SiO2 tozlarından üretilen TiO2-BaO-SiO2 esaslı seramik malzemelerin sinterleme sıcaklığı ve süresine bağlı olarak tane büyüme kinetiği incelenmiştir. Bu amaçla farklı bileşimlerde hazırlanan toz karışımları ZrO2 bilye kullanılarak saf su içerisinde bilyeli değirmende 20 saat süreyle hazırlanmıştır. Toz karışımları kurutma işleminin ardından 1000°C’de 2 saat süreyle kalsine edilmiş ve %5 polivinil alkol ilave edilerek şekillendirilmişlerdir. Numuneler 1175, 1200 ve 1225°C’de 1-4 saat süreyle sinterlenmiştir. Sinterlenmiş numunelerin tane yapısı ve boyutunun belirlenmesi için atomik kuvvet mikroskobu (AFM) kullanılmıştır. Üretilen seramik malzemelerin aktivasyon enerjileri, tane büyüme kinetiği denklemi, Gn=K.t.exp(-Q/RT) kullanılmak suretiyle belirlenmiştir. XRD faz analizi incelemelerinde yapıda BaTiO3 ve Ba2TiSi2O8 fazlarının varlığı tespit edilmiştir
