Molybdenum is a rare refractory metal with low thermal expansion coefficient, good thermal and electrical conductivity, high modulus of elasticity. However, the plasticity and processing properties of molybdenum restrict its application in the field of high technology. In the present paper the sintering process mainly by conventional sintering based on the nano molybdenum powders was studied, the effects of powder size, sintering temperature and soaking time on the density, microstructure, mechanical and physical properties of molybdenum products analysed. The experimental results show that nano Mo powder compact had a lower temperature to densification compared with micron-powder compact. It is suggested that 1550 °C is the most appropriate temperature to obtain the best mechanical and physical properties.
