Thermal emissivity and high-temperature stability of thermal insulating materials produced by mixing powdered porous MgAl2O4 ceramics with commercial insulating castable
2020
Journal of the Ceramic Society of Japan
Conventional industrial thermal insulating materials have a porous structure and provide resistance to thermal conduction. However, this structure permits heat transfer through radiation. Hence, they exhibit high thermal conductivity at temperatures higher than 1000°C. To achieve high total-thermal-insulation efficiency, we recently developed new insulating materials, called THERMOSCATT TM , which greatly suppress radiation heat transfer. Their thermal conductivity was measured to be less than
