Development of technology of tungsten wire production for light sources with the use of blue tungsten oxide as an intermediate product

The paper reveals the types of technological modes of obtaining blue tungsten oxide - an intermediate compound in the production of tungsten powder used in the manufacture of tungsten wire for the electrical industry. The technology of blue tungsten oxide production developed on the basis of these studies was industrially tested and implemented at the Novosibirsk Electro-Vacuum Plant.
