The melting point of tungsten is as high as 3410 ° C. It is a rare metal with the highest melting point. It is widely used in aerospace, biomedical, nuclear industry, telecommunications and electronics industries. The traditional powder metallurgy method for producing complex tungsten products has a long processing cycle, high production energy consumption, and low material utilization. The deep processing technology of tungsten products has always faced challenges.
In recent years, in view of the technical advantages and characteristics of 3D printing, well-known international research institutions have invested in research and development of 3D printing of complex tungsten products in order to explore a new method for deep processing of tungsten products. High-quality spherical tungsten powder is the raw material basis for 3D printing of complex tungsten products. Traditional chemical reduction of tungsten powder by plasma spheroidization has been used to prepare spherical tungsten powder. However, traditional chemical reduction of 2 to 10 μm tungsten powder has fine particle size, high impurity element content, and spherical Problems such as incomplete conversion and high proportion of satellite powder have been plagued by the development of high-quality tungsten products 3D printing technology.
Based on self-developed high-power plasma rotating electrode atomizing powder making equipment, Sialon Metals has developed high-power density plasma technology and combined with developed high-quality 3D printed spherical tantalum powder, spherical molybdenum powder, spherical niobium alloy powder, etc. The process produces high-quality spherical tungsten powder with high purity, good sphericity, and less satellite powder. It meets the requirements of 3D printing for high-quality spherical powder, and can provide a raw material basis for high-quality tungsten 3D printing. The breakthrough of this major achievement will accelerate the development and application of China's rare and refractory metal 3D printing technology.
