Molybdenum disilicide powders were prepared by heating a mixture of Mo and Si powders with Na metal. The single phases of β-MoSi 2 and α-MoSi 2 powders were obtained at 873 K and 1073 K, respectively. The preparation temperature of the single phase α-MoSi 2 powder was 500 K lower than that of the conventional solid state reaction method using Mo and Si powders. The grain size of both MoSi 2 powders was less than 2 μm, and their shape was angular and irregular.
