Diffusion and Thermal Shock Behaviour of Silicate Dental Ceramics

The purpose of this study is to examine the diffusion and thermal shock behaviour alternative dental silicates. samples derived from BaO-SiO2 system have been produced by melting process followed heat treatment. X-ray examinations indicated that amount orthorhombic sanbornite phase rised due treatment temperature as revealed peak intensities. alteration morphology was evident scanning electron microscopy SEM images. Crystallization at low small crystallites coarsening not observed with a rise in temperature. failure after test examined using SEM. A continuous crack geometry very few branching were observed. Diffusivity constant (D) rate vs for present system. Diffusion depth (L) doubled when crystallization applied. Based on obtained results, these silicate might take part further characterization studies be used dentistry materials.
