Abstract
Polymer–ceramic composites are widely used in refractory cables. The ceramic fillers provide high temperature and fire resistance, while the polymer matrix provides flexibility and improved electrical insulation. The properties of the polymer–ceramic composites are determined by the ceramization-forming properties of the corresponding ceramifying powders. Properties such as shrinkage, density, and porosity were characterized to compare the effects of different contents of glass powder. The sintering activation energy was calculated using the logarithmic relationship between shrinkage and holding time. The microstructure, cross-section, and crystalline phases were investigated by scanning electron microscopy (SEM) and X-ray diffraction analysis (XRD) to explore the ceramization process of sericite ceramifying powder. The ceramization process of ceramifying powder is proposed. The results show that during low-temperature sintering, the glass powder and muscovite phases melt and partially transform into α-quartz and albite low during cooling down.
聚合物陶瓷复合材料广泛应用于耐火电缆。陶瓷填料具有耐高温和耐火性能,而聚合物基体则具有柔韧性和更好的电绝缘性能。聚合物-陶瓷复合材料的特性取决于相应陶瓷粉末的陶瓷化特性。对收缩率、密度和孔隙率等性能进行了表征,以比较不同玻璃粉含量的影响。利用收缩率和保温时间之间的对数关系计算了烧结活化能。通过扫描电子显微镜(SEM)和 X 射线衍射分析(XRD)研究了绢云母陶瓷化粉末的微观结构、横截面和结晶相,以探索陶瓷化过程。提出了陶瓷化粉末的陶瓷化过程。结果表明,在低温烧结过程中,玻璃粉和麝香石相熔化,并在冷却过程中部分转化为α-石英和低白云石。
