The high sublimation temperature of SiC (approximately 2700 °C) makes it at the high end of the insolating ceramic operating temperature range.. Silicon carbide does not melt at any known pressure. It is also highly inert chemically.
Its high thermal conductivity, high electric field breakdown strength and high maximum current density make it most promising any type of LENR reaction. SiC also has a very low coefficient of thermal expansion (4.0 × 10-6/K) and experiences no phase transitions that would cause discontinuities in thermal expansion. On the downside, In the 1980s and 1990s, silicon carbide was studied in several research programs for high-temperature gas turbines in Europe, Japan and the United States. The components were intended to replace nickel superalloy turbine blades or nozzle vanes. However, none of these projects resulted in a production quantity, mainly because of its low impact resistance and its low fracture toughness. Silicon carbide is used in high temperature kilns such as for firing ceramics, Silicon carbide is an important structural material in TRISO-coated fuel particles, the type of nuclear fuel found in high temperature gas cooled reactors (such as the Pebble Bed Reactor). A layer of silicon carbide gives coated fuel particles structural support and is the main diffusion barrier to the release of fission products. My belief is, if it can handle fission of U235, it should handle LENR.
