Industrial titanium tungsten powder has better anti-sintering properties, and its preparation is directly added to the tungsten salt precursor in the process of preparation of partial titanate, which is formed by calcining and other processes.

Preparation
Industrial titanium tungsten powder preparation is in the process of preparing metatitanic acid directly to the tungsten salt precursor (tungsten acid, ammonia, partial ammonium tungstate, or of para-ammonium tungstate, tungsten acid, etc.), and then formed by calcining process etc.
