Tungsten steel, density, thermal

Table 3 presents the characteristics of ceramics that seal rings are usually made of. In comparison with the reference materials (table 1), the tungsten carbide density is near twice the steel density, moreover, the thermal diffusivity d of the rotor is divided by 2.5. Silicon carbide has a conductivity that is ten time that of graphite its density is greater as well, and the thermal diffusivity dj of the stator is multiplied by 4.
