High quality spherical tungsten powder has good economic benefit and broad market prospect, is widely used in the thermal spraying, porous materials and powder metallurgy industry, can be prepared by the method of equal pressure air blowing classification.
Application
The rocket nozzle bushing with high quality spherical tungsten powder has good anti-fracture and corrosion resistance under thermal stress.
Porous tungsten prepared with high quality spherical tungsten powder has a more uniform pore, therefore in the process of production can control the product according to the process conditions of permeability, it is gradually replacing conventional tungsten powder, used to make porous tungsten components, such as high power pulse microwave tube cathode, barium tungsten cathode tube, high temperature gas distribution plate and gas filter material, etc.
Preparation
High quality spherical tungsten powder which particle size distribution and spheroidization rate meet the requirements can be prepared by the method of equal pressure air blowing classification.
