Synthesis of a MoSi2-Based Powder Material Under the Influence of Pressure and Shearing

Resumo

The SHS-grinding method was employed to prepare molybdenum disilicide powder material through the reduction of molybdenum oxide by aluminum and silicon. It is shown that the mechanical action applied to the material after the passing of an SHS-combustion wave through it can destroy the synthesized briquette created by the conventional self-propagating high-temperature synthesis (SHS) method. The increase in the intensity of mechanical action in the course of SHS-grinding breaks the agglomerated particles up into finer fractions, and also changes the morphology of the synthesized powder.
