Ceramic Materials For Nuclear Industry

Oct. 16, 2019

Since the first nuclear reactor was built in the United States in 1942, the nuclear industry has grown for almost 70 years. During this period, the development center of the nuclear industry was transferred from nuclear weapons to nuclear energy applications. At present, countries have started to study fusion nuclear reactors together. During this period, the materials used in the nuclear industry also continued to develop. Among them, ceramic materials have been valued in the choice of materials in the nuclear industry and widely used in nuclear reactor raw materials, components, and nuclear waste processing.

The massive application of ceramic materials in the nuclear industry is inseparable from its own performance advantages. Ceramics originally had the characteristics of high strength, high rigidity, corrosion resistance, high temperature resistance, and good chemical stability. With the further development of ceramic materials (such as the development of ceramic matrix composite materials), some weak points in material properties like poor toughness and difficult processing have also been improved. In particular, some specific ceramics also have the characteristics of resistance to radiation, low activity, and ability to absorb neutrons. These properties are helpful for their application in nuclear environments with high temperature and high radiation.
