Sintering of Alumina-5 wt% composite powder by Inductively Coupled Argon Plasma (ICP) is studied. The precursor was synthesized under milling conditions in an Attritor in which it exhibited limited architecture of Interpenetrating Phase Composites (IPC). The precursor was formed without binder. After 30 sec of sintering, the compact was only 85% dense and exhibited evidences of a liquid phase. The optimal sintering period for the present case was about 60 - 120 sec where >99% dense compacts have limited IPC microstructures and optimal toughness. If the sintering is prolonged to 240 sec, the toughness and density values decreased and a few voids appeared in the microstructure. The grain size, density, hardness values of the compacts are included.
