摘要

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 1073K, respectively. The preparation temperature of the single phase á-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 ìm, and their shape was angular and irregular.
