 Spark Plasma Centering is a new technology for preparing ceramic materials. This technique involves heating a powdered material in a chamber using electrical discharge, which causes it to fuse together under high pressure. A thermal electric mechanical coupled model was developed to simulate the process, taking into account the effects of temperature, electricity and mechanical forces. The model was able to accurately predict the centering behavior of boron carbide powders at four different temperatures. This article was authored by Song Zhang, Wei Lu, Weiman Wang and others.
