Development of an Innovative Carbon-based Ceramic Material Application in High Temperature, Neutron and Hydrogen Environment

摘要

In the framework of the European Fusion Research Program, a great effort has been made to develop an innovative carbon-based ceramic material to meet all of all operational requirements. After a decade of research and development, It is succeeded to develop an advanced material: namely, a 3D CFC, contains about 8-10 at% of Silicon with porosity is about 3-5% . This advanced ceramic material possess very high thermal conductivity, dimensional stability under the neutron irradiation, lower chemical erosion (longer life time), lower tritium retention and lower reactivity with water and oxygen (safety concern). This innovative ceramic materials seems very promising for application in the high temperature, neutron and hydrogen environment. A detailed discussion on development, properties and application of material is presented.
