【Chinatungsten】Titanium tungsten powder

Study pointed out one method for preparing titanium tungsten powder of denitration catalyst with the steps like following:
1. Preparation of meta-titanic acid: Respectively add titanyl sulfate solution and dispersant into the thermostatic reactor, stirring and adding carbonate aqueous solution dropwise in a constant temperature, adjusting pH value to a suitable range and keep stirring until obtain solids, then washing, drying the solids to obtain meta-titanic acid particles;
2. Preparation of composite particles: Crushing the meta-titanic acid particles and dissolving in the second reactor with solution containing tungsten, followed by adding Tween 80 and stirring at a constant temperature, then heating to evaporate and obtaining the composite particles;
3.Post-treatment: Drying and calcining the composite particles to obtain titanium tungsten powder.
