摘要
研究低Ｔ＿ｃＰＴＣＲ复合材料的制备工艺，测试所制成样品的阻温特性。通过样品Ｘ射线定性相分析，探讨该复合材料所表现的ＮＴＣ阻温特性机理。
The preparation technology of PTCR matrix composites at low T_c is studied,and the resistivity-temperature properties of the samples are measured Based on the analysis of the X-ray diffraction spectraof the samples,the mechanism of the NTC resistivity-temperature properties of the composites is discussed.
