hard-sintering transition metal boride

Expanding application by increasing density through low-temperature sintering !

Overview

　With the increasing demand for highly efficient energy sources and the development of aerospace technologies, materials used in these fields must be able to withstand harsh environments. Among the materials expected in the aerospace field, TiB₂ is used as a heat-resistant and wear-resistant material because of its high melting point and strength, as well as its high electrical conductivity, etc. However, TiB₂ is a hard-sintering material that requires high temperature and pressure for sintering, which limits its domain of usage.
　The sintering technology of this invention has an effect similar to the original properties of transition metal boride even with the addition of auxiliary agents. This result expands the possibilities of using transition metal diborides as structural components, which have been limited to powder and thin film applications due to their difficult sintering properties.
