Sintering of Alumina using Microwaves and Plasma assisted Sintering

Abstract

1000 Watt, 2.45 GHz Magnetron, coupled with WR-340 type waveguide is used to sinter pellets of 0.05 micron Alumina powder, made by uniaxial hydraulic press, using Microwaves by focusing them on the pellets. Moreover, three such assemblies are used in combination to generate plasma by utilizing high pressure gas and focusing Iron rod, and using the plasma to attempt to sinter the same powder.
