    Introduction

    The production method of tungsten acid to produce ammonium metatungstate is applied ammonia to dissolute tungsten acid. The detail process is adding dissoluted ammonium tungstate into boiled de-ionized water, making the fluid PH 8 after stirring, decreasing the PH again after adding acetic acid, and stopping heating when the density is 1.5~2g/cm3. After cooling and filtering, adding ethanol to precipitate, AMT is produced after drying and crushing.
