Li Dongying, a hundred-year-old academician of rare metal metallurgy and materials, passed away

SMM: Li Dongying, an expert in rare metal metallurgy and materials and academician of the Chinese Academy of Engineering, died in Beijing on September 22nd at the age of 100.

Comrade Li Dongying was born in Beijing on December 14, 1920. He graduated from Beijing Furen University in 1948 and was elected as an academician of the Chinese Academy of Engineering in 1995. He has successively served as a technician of the Planning Office of the Northeast Nonferrous Metals Administration, the factory director of Shenyang Ore dressing Agent Plant, the head of the mineral separation section and factory director of the Northeast Nonferrous Metals Administration, and the deputy director of Beijing Nonferrous Metals Comprehensive Research Institute. Beijing Nonferrous Metals Research Institute Deputy Chief engineer, Alloy processing Room Director, Vice President, Deputy Secretary of the Party Committee, Chief engineer, Deputy Director of the Reform Commission, head of the Science and Technology Office of the Ministry of Metallurgy, Head of the Science and Technology Department of the State Administration of Nonferrous Metals Industry, Director and Managing Director of the Science and Technology Department of China Nonferrous Metals Industry Corporation.

Li Dongying is one of the pioneers of China's rare metal industry and the first person in China to apply rare earths to agriculture. In the 1960s, Li Dongying pioneered the use of rare earth elements in grain and cash crops in the face of widespread skepticism about the "impossible". Practice has proved that rare earth elements can increase agricultural output, and rare earth agricultural use continues to this day.

He presided over the successful research on the production methods of more than 30 kinds of rare metals, ensuring the new materials urgently needed by the military industry, such as "two bombs and one satellite," and cutting-edge technologies such as large-scale integrated circuits, and presided over the application and promotion of titanium with remarkable economic benefits. he has published more than 10 academic papers and edited 40 volumes of a large series of books "Progress in Nonferrous Metals".

He devoted his life to combining what he learned with nation-building: "the needs of the country are the most important." I can change majors, projects and jobs at any time as long as the country needs it. "
