摘要：

A new method for the reduction of MoO3 using Ca as a reducing agent was developed. A low oxygen Mo powder can thus be prepared by two-step reduction process: the first step reduction involves a contact type method while the second step reduction uses a non-contact type method involving Ca vapour followed by additional deoxidation. The oxygen concentration in the resultant Mo powder was similar to 2800 ppm, which was much lower than that of commercial Mo powder (>4400 ppm).
