Physical properties of cullet-clay glass ceramic containing titanium nitride

Recycle glass as a major component in ceramic fabrication has received tremendous attention due to multi advantages as a starting material. A series of glass ceramics based on recycled glass cullet-kaolin clay containing titanium nitride has successfully been made. The X-ray diffraction technique has been used to characterized the ceramic. Meanwhile, the physical properties such as density have been determined using the Archimedes Principle and their mechanical characteristic such as Vickers hardness and Young's Modulus has been determined in a usual manner. It is found that the ceramic is characterized by the occurrence of major crystalline peaks of Quartz and Tridymite while alumina and titania coexist as the minor phases. The density is observed to vary depending upon the cullet content while the hardness and elasticity are very much dependent on the concentration of titanium nitride. The SEM image indicates that for higher TiN content, the pores on the microstructural surface seem to be dispersed thus producing a smoother surface
