prepared by the dry-pressing molding. The influences of compression pressure, speed, holding time and forming agent on the BeO ceramics molding were investigated through analysis of the body density, microstructure of the BeO ceramics. The results show that the compression pressure, speed, holding time and forming agent can obviously improve the body density of the BeO ceramic, thereby enhance......

measurement methods for pressure distributions were introduced and compared. Both the perforated sheet forming test and the pressure film were found to be effective method to measure pressure distributions. The cost of perforated sheet forming test was cheap and the pressure film was easy to operate. Three different pressure distributions were measured and discussed, namely single pressure......
