Xu Caidong (; 27 March 1919 – 14 April 2016) was a Chinese metallurgist, politician, and academician of the Chinese Academy of Sciences (CAS).
Xu was born in Fengxin County, Jiangxi. He graduated from Tangshan Engineering College, Chiao Tung University in 1943. He went to France in 1946 and obtained a doctor's degree from École Nationale Supérieure d'Électrochimie et d'Électrométallurgie de Grenoble (ENSEEG) in 1949.[1] After returning to China, he joined the faculty of the Guizhou University School of Engineering in the same year. He joined the Jiusan Society in 1956.[2]
Xu's research was mainly focused on the physical chemistry of metallurgy. He operated the blast furnace for smelting mercury, the industrial synthesis of potassium permanganate by the electrolytical method, and the industrial synthesis of calcium-magnesium phosphate in the shaft furnace.[3]
Xu was elected an academician of the Chinese Academy of Sciences in 1980.[3] He became the vice-governor of Guizhou Province in 1983.
