Academician He Jilin has been engaged in the research on the fine structure of tantalum-niobium materials and its influence on their properties for a long time, and has high research attainments on the internal influence of sodium reduction mechanism of tantalum powder on its chemical and electrical properties. He is an important figure in the revolutionary progress of preparing tantalum metal by potassium sodium fluotantalate reduction method (series) in China.
Many research achievements have been made in the field of new materials of rare metals such as tantalum, niobium and beryllium. The technology, process and method of tantalum-niobium metal smelting with independent intellectual property rights have been researched and pioneered, and the engineering application has been realized. He has presided over and guided the research on special copper alloys, magnesium and magnesium alloys, titanium alloy processing, tantalum electrolytic capacitors, battery materials, cermet targets and many other new materials and technologies.
Academician He Jilin won two second prizes for national scientific and technological progress and four first prizes at the provincial and ministerial levels. He has published more than 50 academic papers and nearly 20 invention patents. In 2007, "Micro-nano Characterization Method of RTO Metal Embedded Slices" won the "Second Prize of National Technological Invention"; 20 12 "production technology and application of key materials for ultra-miniature tantalum capacitors" won the second prize of national scientific and technological progress.
