Use of Hafnium as a Sintering Activator of BL Group Composites in the cBN–HfC System
Source abstract
Abstract
Abstract This study examines selected aspects of the formation of nonporous ceramic-matrix composites of the BL group in the cBN–HfC system, where hafnium micropowder serves as a sintering activator. The results demonstrate that, during HPHT experiments at 2300°C, the system undergoes reactive sintering characterized by the disappearance of the metallic phase and the formation of fine-grained HfB2 through two mechanisms, with a volume fraction of up to 8%.
