With increasing sintering temperature, the joint of graphite and BN was increased and also there was transition layer in the interfaces relative to HP.
随着烧结温度的升高，元素扩散加剧，过渡层的厚度越厚，材料的层间界面结合强度升高，石墨层与BN层结合的越好。
Hydroxyapatite ceramic powder was synthesized by chemical coprecipitation process. The. maxillofacial bone materials were made by slip-casting. HP and HIP post-sintering method.
