Cerium Tungsten Powder Preparation Method

The present invention provides a method for preparing cerium tungsten powder. Characterized in that:

Added to the tungsten trioxide or ammonium paratungstate after calcination at 800-850 ℃ WO3 in the cerium acetate solution,then stirred with a high pressure that concentrated by evaporation, drying, and finally through the primary and secondary reduction and sieved to prepare a tungsten ,which can group containing 1-8% (by weight), cerium oxide, cerium tungsten powder.

Tungsten cerium powder production method of the invention solves the conventional tungsten cerium powder preparation process of environmental pollution problems, the present invention is prepared by the process containing 1-8% (weight) of the tungsten raw powder of cerium oxide can be prepared in the cerium content 1.0-6.0% (weight) of the cerium-tungsten electrode material, thereby overcoming the electrode material is tungsten, cerium, cerium oxide content of more than 1.0% of the difficulties in the process, and the electrode material is tungsten, cerium 4-6% there are some substantive breakthrough in the range.
