Abstract
A fabrication method for a molybdenum disilicide sintered body in which a molybdenum disilicide powder having excellent oxidation resistance is sintered in a low-temperature sintering method and compacted at a low temperature and under no pressure, includes carrying out a milling on a molybdenum disilicide powder at a low temperature, providing a diffusion path required to sinter the molybdenum disilicide on which a milling is performed, and sintering the resultant powder under the atmosphere of hydrogen or argon gas.
