Tungsten - Cerium Electrode Manufacturing Method

The method of manufacturing an electrode cerium - the present invention provides a production of tungsten. Mainly characterized in that:

Ammonium solution tungsten and rare earth oxides as raw materials, by suspension crystallization, prepared paratungstate - rare earth oxide crystals, after reduction, burn, melt vertical machining processes, and ultimately made ​​products.

The present invention is relatively good compared with the existing wet, simplifying the two processes, save time and reduce energy consumption and improve productivity, and eliminates the process of release of NO2, SO2 and other hazards to the environment and the human body gas. Distribution of rare earth oxides in the matrix of tungsten in uniform dispersion, excellent electrode arc performance, long service life.
