Preface
Writing background and significance
As an advanced metal material with high melting point, high density, high thermal conductivity and good fluidity, spherical tungsten powder has shown more and more extensive application potential in high-end technology fields such as additive manufacturing (3D printing), powder metallurgy, aerospace, microelectronics, energy materials, etc. in recent years. Compared with traditional irregular tungsten powder, spherical tungsten powder has higher forming uniformity, better stacking density and better process adaptability, and has become one of the important raw materials for manufacturing high-performance complex components and realizing intelligent manufacturing.
At present, with the development of high-end manufacturing technology and the strict requirements of downstream application fields on powder quality, the basic research, industrial preparation technology, standard testing methods, application expansion and green sustainable development of spherical tungsten powder at home and abroad are increasingly concerned. However, the systematic data on spherical tungsten powder is still relatively scattered, lacking a comprehensive, in-depth and authoritative professional reference book. Therefore, the compilation of the “Encyclopedia of Spherical Tungsten Powder” aims to fill this gap, build a knowledge system and technical platform in the field of spherical tungsten powder , and serve scientific research, engineering and industrial practice.
Strategic Value of Spherical Tungsten Powder
Tungsten is one of my country’s important strategic resources and is widely used in the manufacture of high-temperature structural parts, armor-piercing warheads, nuclear shielding materials, electronic electrodes and other key fields. In the context of increasingly fierce global competition for high-performance powder materials, spherical tungsten powder, as a high-value-added, high-tech barrier frontier material, has become an important indicator of a country’s advanced manufacturing capabilities.
Spherical tungsten powder can not only significantly improve the material utilization rate and forming quality of additive manufacturing , but also meet the urgent needs of the new generation of microelectronic packaging, energy conversion devices and complex structural parts for high-precision and high-density materials. In the future, spherical tungsten powder will play a more important role in key “neck” technology fields such as military industry, aviation, energy, medical care, and nuclear industry. Therefore, promoting the development of systematic technologies such as the preparation, testing, and application of spherical tungsten powder is of great strategic significance for improving the country’s material security capabilities and the core competitiveness of the manufacturing industry.
