摘要
本文采用ＣＯ＿２激光器作热源合成了Ａｌ＿２Ｏ＿３－ＷＯ＿３系热敏电阻材料，该材料具有负的温度系数，在一定温区内阻温特性呈线性变化。并对材料的导电机理进行了初步探讨。
The electronic ceramics consisting of Al_2O_3-WO_3 system was synthesized by laser sintering technique. This material has negative temperature coefficient(NTC)and linear resistance-temperature(R-T)properties.In the range of 10℃ to 150℃。X- ray photographic powder analysis in dicated that the conducting phase in the specimen is Al_xWO_3──a nonequlibrium product.
