Abstract
The effect of microwave sintering on the densification of forsterite ceramic was investigated. Forsterite powder was prepared via solid-state reaction method with the application of attrition milling and heat treatment. The forsterite compacts were microwave sintered at 1100oC to 1250oC with 30 min holding and a ramping rate of 50oC/min. The samples were then characterized in terms of phase stability, relative density and microstructure evaluation. This work revealed that microwave sintering is beneficial in producing dense forsterite at lower sintering temperature with shorted operating hour (< 1 hr). Highest relative density of 87.9% was successfully obtained at 1250oC with estimated grain size of lesser than 1 �m as compared to conventional sintering. � 2016 Trans Tech Publications, Switzerland.
