Abstract:

The heat capacity, thermal expansion, and thermal conductivity were measured for 3 refractory materials, including ATJ graphite, W, four nitrides, two borides, a silicate, and four carbides. The temperature range was from 500 to 5000 F. The heat capacity varied considerably with temperature and demonstrated marked inflections at specific temperature ranges. The thermal expansion parallel with the press direction was in the range of 3 x 10 to the -6th power in.in.degree F and varied significantly with the prior thermal history of the specimen. Most of the materials failed below the handbook values for their melting or deterioration temperatures.
