Synthesis and Characterization of Functionally Graded Ceramic Material for Aerospace Applications

The aim of this research work is to study the density and dielectric properties of the functionally graded ceramic material with fused silica. The low density and low dielectric properties of this material made it use in the aerospace applications significantly such as, radomes which are used in protecting the radar antenna from high temperature and typical environmental conditions. The fused silica samples are produced by slip casting process with uniform density and sintered up to high temperatures to achieve desired strength, density and the dielectric properties. It has been observed that the properties have shown significant change with the change in time and temperature of the sintering process.
