Chemical reagent Ammonium tungstate spot 

Ammonium tungstate was calcined into tungsten trioxide in air, and then submicron tungsten powder was prepared by cyclic redox method. The submicron tungsten powder prepared by the method has the advantages of less pollution, narrow particle size distribution, simple and easy process route, easy control of process parameters, simple equipment and suitability for industrial mass production, etc., and the obtained submicron tungsten powder particles are spherical. , which is conducive to the uniform shrinkage of the compact of tungsten powder during the sintering process, and can achieve good size control Company Profile Jiangsu Leiji Metal Materials Co., Ltd. is a manufacturer of sodium tungstate, tungsten bar, sodium molybdate, ammonium molybdate, molybdenum bar, and other tungsten and molybdenum series products. And concurrently operate waste tungsten, waste molybdenum, ferrovanadium, ferrotungsten, ferromolybdenum and other charge materials, and various kinds of tun…
