Radiation effects of sic on nuclear reactors

Abstract

Silicon carbides have enjoyed both fundamental study and practical application since the early days of nuclear materials science. In the past decade, with the increased interest in increasing efficiency, solving the real issues of waste disposal, and the constant mission to improve safety of nuclear reactors, silicon carbide has become even more attractive. This ceramic material has wide range of applications due to its high strength, low density, thermal shock resistance. The purpose of this paper is to discuss recent research that does not only strives to understand the remarkable radiation stability of SiC but the radiation effect of SiC under high temperature. This article will expound on the fabrication of SiC, the mechanical behavior and thermaity with regards to the phase transformation which occurs at refractory temperature.
