Zhou Guozhi

Zhou Guozhi, born in Nanjing, Jiangsu Province on March 25, 1937, is a physical chemist of metallurgical materials, academician of Chinese Academy of Sciences, Professor of Beijing University of science and technology, director of China Society of metals, editorial board member of International Journal of mining and metallurgy, and part-time professor of Shanghai University, Shanghai Jiaotong University, Anhui University of technology, Chongqing University and other universities.

Zhou Guozhi graduated from the Department of metallurgy of Beijing Institute of iron and steel in 1960 and stayed in the University ahead of time to teach in the Department of physics and chemistry. In 1964, he published his first academic paper, the application of theta function method in Gibbs Duhem relationship. In 1979, he went to Massachusetts Institute of technology to study. In 1984, he was promoted to Professor and doctoral supervisor, and won the first batch of "young and middle-aged experts with outstanding national contributions"; Since then, he has given lectures and cooperated in scientific research abroad for many times. He has served as a visiting professor in MIT, Boston University and other universities in the United States. In 1995, he was elected as an academician of the Department of technology and science of the Chinese Academy of Sciences.

Zhou Guozhi is mainly engaged in the teaching and research of basic theory of metallurgical process, metallurgical materials and physical chemistry.

Character experience

In 1937, Zhou Guozhi was born in a scholarly family in Nanjing, and his native place is Chaoyang, Guangdong. His father Zhou Xiuqi went to Germany to study, and after returning home, he taught in Shanghai Jiaotong University.

In 1956, he was admitted to the metallurgy department of Beijing Institute of iron and steel (now Beijing University of science and Technology).

In July 1960, he graduated from the metallurgy department of Beijing Institute of iron and steel and stayed in the University ahead of time to teach in the Department of physics and chemistry.

In 1964, he read an article written by Zhou Yuanxi, director of the Institute of metallurgy, in Acta metallurgica Sinica, which mentioned that there was a problem that could not be solved. He wrote to Zhou Yuanxi after nearly half a year of solving the problem. On this basis, he published his first academic paper, the application of theta function method in Gibbs Duhem relationship.

In 1979, after passing the examination, he went to MIT to study (until 1982).

In 1984, he was promoted to Professor and doctoral supervisor.

In 1990, he was a visiting professor at MIT, Boston University and other universities (until 1994).

In 1995, he was elected academician of the Chinese Academy of Sciences, under the Ministry of technology and science.

In July 2001, he worked as a part-time professor and doctoral supervisor in school of materials science and engineering, Shanghai University.

On March 15, 2017, he was awarded honorary member by Japan iron and Steel Association, and was selected by Wei Shoukun science and technology education foundation of Beijing University of science and technology on the same day, and won "Wei Shoukun metallurgy Gold Award (Gold Award)". On March 25, "academician Zhou Guozhi's 80th birthday and Symposium on basic metallurgical theory and discipline development" was held in the lecture hall of the conference center of Beijing University of science and technology.

Main achievements

Achievements in scientific research

The main work is in melt thermodynamics and metallurgical process theory. A series of formulas for calculating the thermodynamic properties of melts in various systems are derived and some principles are summarized. The new generation of solution geometry model proposed in this paper solves the inherent defects of geometry model in the past 30 years, and opens up a way to realize the computerization of model selection and calculation. The migration of oxygen ions in electrolyte was studied systematically, which laid a foundation for describing and simulating various smelting processes. Its work has been cited by experts and scholars at home and abroad to deal with thermodynamics and dynamics problems in various systems such as alloy, molten salt, slag and semiconductor materials, and has been systematically incorporated into many university textbooks by peers.

Zhou Guozhi's scientific research field is mainly in "metallurgy and physical chemistry of materials". Its main contributions can be summarized as follows:

① Calculation of physicochemical properties of multicomponent melts and alloys. A series of formulas for calculating thermodynamic properties and phase diagrams of various systems are derived, and some new principles and methods are summarized. The new generation of solution geometric model proposed in this paper solved the inherent defects of geometric model in the world for more than 30 years, and opened up a way for the selection of model and the complete computerization of calculation. After further development, the geometric model has developed into a unified model, put forward the phenomenological theory, and further extended the calculation of thermodynamic properties to a variety of physical and chemical properties In the calculation.

② Theory and application of oxygen ion migration. Zhou Guozhi and his research team systematically studied the migration law of oxygen ions, and applied the theoretical results to various metallurgical processes. New metallurgical concepts and processes such as "pollution-free deoxidation" and "pollution-free extraction" were proposed, which laid a foundation for describing and simulating various smelting processes.

③ The physical and chemical behavior of materials in micro particles. This paper mainly studies the physical and chemical properties and reaction mechanism of materials under micro particles, establishes a gas-solid reaction kinetic model (RPP model) based on real physical images, and comprehensively describes the influence of various factors (temperature, pressure, shape, size, product structure, etc.) on the reaction rate. It has been successfully applied to nano materials, hydrogen storage materials and Sialon materials.

Many of Zhou Guozhi's scientific research achievements have been applied to alloy, molten salt, slag, semiconductor materials and other systems by domestic and foreign experts and scholars with "Zhou model" and "Zhou method" to deal with thermodynamics and dynamics problems. The research achievements have also been systematically incorporated into many university teaching books and Monographs to guide doctoral and master's thesis work.

By 2017, Zhou Guozhi had won one third prize of National Natural Science Award, one first prize of science and technology progress award of State Education Commission, one first prize of science and technology progress award of Ministry of metallurgy, one first prize of Shanghai Science and technology award, and two second prizes of science and Technology Progress Award of State Education Commission.

Zhou Guozhi has published more than 150 papers, obtained two Chinese patents and three American patents.
