【Abstract】 PZT—YBaCuO composite oxde ceramices were prepared and electrical conductivities were determined in different tempereture. It shows that the material have stronger thermistor functions.The electrical conductivity from 3.33×10 -5 Ω -1 cm -1 to 1.04×10 -1 Ω -1 cm -1 with tempereture from roomtempereture to 945℃. It changed four order of magnitudes.更多还原
