Synthesis and fabrication of pollucite glass-ceramics was investigated. The mixture which was measured to be the stoichiometric ratio of pollucite was melted by using an arc melting technique to synthesize the material in glass state. Milled powder of the glass was mold pressed and CIPed to obtain green compacts. Dense pollucite glass-ceramics were obtained by heat-treating the compact at 1400°C for 4h in air. Enhanced densification of the present material was ascribed to the viscous deformation of the glass phase. Fracture strength and the Young's modulus of the resultant pollucite glass-ceramics were 102MPa and 100GPa at room temperature, respectively. Average fracture strength exhibited 128MPa for specimens measured at 1000°C. Thermal expansion coefficient of the sample was 2.7×10-6/°C between room temperature and 1000°C.
