Abstract

Transparent alumina samples have been prepared by microwave sintering processing. Transparent alumina can be achieved at lower sintering temperature and shorter sintering time by microwave sintering. Transmittance is optical property which is highly dependent on the grain size and residual porosity which lead to real in line transmittance. A systematic experimental design is used to study transmittance of alumina. The following work was carried out using MgO as sintering aid for all Al2O3 samples. By using optimized parameters, the transmittance of single crystal alumina was obtained about 35% - 20% in visible wavelength for 2 mm thick samples. The results are significantly better.
