Abstract

The oxide ceramic powders have been sintered with a high power CW CO₂ laser. The products of Al₂(WO₃)₂ as a new compound which can not be found in 2D equilibrium phase diagrams. The hardness of laser synthesized materials are shown to be higher than that produced with the general sintering method in furnace. The microstructure and character is of oxide ceramics synthesis using CW CO₂ laser have investigated. We found that the products of laser sintering Al₂O₃-50mol percent WO₃ have the electrical resistance characters varied linearly of negative temperature coefficient from the room temperature to 220 degrees C.
