Abstract

This paper introduces laser powder sintering as a new technique to synthesize electronic ceramics consisting of A12O3-WO3 system. This material has some unique properties such as linear decrease in resistivity of A12O3- 50 mol % WO3 specimens with increasing temperature over the range of 10 ℃ to 150 ℃. X-ray photographic powder analysis indicated that the conducting phase in the specimen is a nonequilibrium product:A1xWO3.
