彩色显像管成型锥显微结构及抗侵蚀性研究

摘要

采用光学显微镜(DM)、x-射线衍射(XRD)及拉曼光谱研究了彩色显像管成型锥的显微结构及其抗玻璃液的侵蚀性.结果分析表明:该成型锥属多相非均一结构,有利于提高材料的高温力学性能,在高温下成型锥中的莫来石相与显像管玻璃熔体中的PbO、SrO、K2O、Na2O等组分反应生成物,在成型锥的使用温度下多为高粘度,高温稳定相,同时由于"饱和状态"降低了玻璃熔体对成型锥的进一步侵蚀.%The microstructure and glass melt corrosion resistance of color picture tube forming cone were investigated by means of optical microscope, x-ray diffraction and Raman spectrometer. The experimental results indicate that this forming cone has multi-phase heterogeneously structure, which helps improve the high temperature mechanical properties, at high temperature, the production of reaction between mullite in forming cone and PbO、SrO、K2O、 Na2O which came from glass melt are with high viscos, and with high temperature stable phase. Meanwhile the hyper saturated state is of benefit to glass melt corrosion resistance of forming cone.
