| 摘 要： | 采用原子吸收光谱(AAS)、X射线衍射(XRD)、偏光显微镜(OH)和分析型透射电镜(TEM)等技术手段，对贵州产70kN和日本进口120kN、210kN三类瓷绝缘子的化学组成，矿物成分特征和产品性能的关系进行了研究。结果表明，三类产品的主化学成分为siO2、Al2O3。矿物相有刚玉、英来石、石英和长石。产品除含有偏光显微镜可分辨的晶体外，在电镜下还见有微米级以下的显微矿物。不同等级的产品，不但结晶相含量不同，晶体大小、分布状态各有特征。指出贵州产70kN产品应控制K20含量，并用部分工业氧化铝替代铝矾土，通过调整工艺提高结晶相的含量。

| Abstract: | This paper deals with the relations between the compositional characteristics and performances of high-strength suspension porcelain insulators of 70kN, 120kN and 210kN by the AAS, XRD, OM and TEM techniques. The results showed that the major chemical compositions of porcelain insulators are SiO_(2)and Al_(2)O_(3), the major crystal-phases are corundum, mullite, quartz, feldspar and so on. These insulators are microcrystals of micrometer scale except crystals under microscopic observation. These three samples show some difference in crystalline weight, crystal size and distribution. The raw materials of 70kN can be roasted to become high-strength porcelain insulators by adjusting K_2O weight and uniform distribution in the construction of porcelain insulators. |
