Influence of Diluent Types on Self-propagating High Temperature Synthesis of Tungsten Powder AITranslate
Abstract AITranslate
Using tungsten trioxide, magnesium powder and diluents as raw materials, tungsten powder was prepared by self-propagating high temperature synthesis method.The influence of diluent types on the properties of tungsten powder in different raw material states was studied, and the determination of the best reaction diluent and process improvement for the preparation of tungsten powder by self-propagating high temperature synthesis were further explored.The experimental results show that elemental tungsten powder can be obtained regardless of whether the reactants are in powder state or pressed state, and the particle size of tungsten powder prepared in powder state is smaller.Different types of diluents have a significant effect on the morphology of the product tungsten powder.Using MgO as the diluent, the particles of the product tungsten powder is relatively larger and the distribution is relatively uneven.Using K2CO3,Na2CO3and Li2CO3as the diluent, the particle size of the obtained tungsten powder is un-even and increases in turn.NaCl is the best diluent for the preparation of tungsten powder by self-propagating high temperature synthesis method, the morphology of the obtained tungsten powder is the best, and the overall particle size of tungsten powder is less than 200 nm.
