Explanation
It is a new type of electron emission source materials. It has excellent physical chemistry and mechanical properties such as no grain boundary, few crystal defects and isotropy; Its preparation methods mainly include electron beam suspension zone melting method, droplet plasma arc melting method and strain annealing method. It is widely used in electronics, laser, holographic technology, aerospace high-energy physics, space technology and other fields.
