摘要
PURPOSE: High melting point of rare metal and a low-temperature sintering method of a high melting point of rare metal are provided to ensure the uniformness and mechanical properties of a product manufactured through a sintering process since mixed powder, on which the same kinds of nano particles are deposited, is supplied to the surface of a micro particle. CONSTITUTION: A low-temperature sintering method of a high melting point of rare metal comprises next steps. Micro powder of a high melting point of rare metal is formed(S10). A nano particle with the same chemical composition to the micro powder is formed(S12). The nano particle is deposited on the surface of the particle of the micro powder to form mixed powder(S14). The mixed powder is sintered in an inert atmosphere(S16).
