Fine spherical tungsten powder is spherical tungsten powder with finer grain size, has excellent characteristics, widely used in powder metallurgy, satellite positioning propeller, rocket nozzle bushing, can use the special tungsten powder reduction technology, the traditional preparation equipment and process.
Preparation
The special reduction technology of tungsten powder can be used to prepare fine spherical tungsten powder through traditional equipment and process. When producing spherical tungsten powder with fine grain size, iron oxidation not only increases the oxygen content of tungsten powder, but also the heat released by oxidation will cause the tungsten powder to spontaneously ignite, causing unnecessary loss in production. In production, the impurity iron should be strictly controlled.
Application
In the process of powder metallurgy, the compaction of fine spherical tungsten powder in sintering process is very uniform and can achieve good size control.
The fine spherical tungsten powder is applied to high power pulse microwave tube cathode, artificial satellite positioning propeller, rocket nozzle bushing, etc.
