【摘要】 建筑卫生陶瓷生产过程中的塑性形变成为阻碍产品轻量化发展的重要问题,特别是高温下塑性形变的微观机理及其抑制方案是亟需深入探索的关键科学问题。本文高度综述了高温熔体中晶体的形貌、粒径及分散程度对高温液相粘度的影响以及液相量、液相粘度对陶瓷高温塑性形变的影响。减少液相量和提高液相粘度都会减小建筑卫生陶瓷高温塑性形变量。但规律性的数学模型的探讨还有待后续研究。更多还原

【Abstract】 The deformation of building ceramics & sanitary ware during the manufacturing process has become a big issue which effects the development of lightweight body on the ceramic productions.Especially the micro-mechanism and regulation of pyroplastic deformation are the critical scientific issues.The paper summarized the influences of morphology of crystals,the size of particles and the distribution of the solid phases in the liquid on the liquid viscosity.Reducing the content of the liquid melt and increasing the viscosity of the liquid phase would make the building ceramics & sanitary ware tough.The theoretical mathematic modeling should be explored in future.更多还原
