Porcelain?Raw Materials, Processing, Phase Evolution, and Mechanical Behavior
Porcelain represents the foundation of the ceramics discipline and one of the most complex ceramic materials. Composed primarily of clay, feldspar, and quartz, porcelains are heat-treated to form a mixture of glass and crystalline phases. This review focuses on raw materials, processing, heat treatment, and mechanical behavior. Because of the complexities of the porcelain system and despite the substantial amount of research already conducted within the field, there remain significant opportunities for research and study, particularly in the areas of raw material understanding, processing science, and phase and microstructure evolution.
This article introduces the general situation of Beijing-Tianjin Products Pipeline,analyzes the influence of solid matter on products quality and the necessity to pig the pipeline. The authors describe the pigging practice of the pipeline and put forward suggestions in pigging operation.
