Its thermal conductivity is 0.25 W/m · K or less. It can be used up to 1,450 ° C with characteristic strength 10 MPa or more and will be used in industrial furnaces where at present only 30 % of the energy above 800 C is used for the process. The development was done within the NEDO project TherMAT, directed at utilizing unused heat energy.
