Changes in bulk density, shrinkage, and weight are given for carbon and for dry‐pressed specimens of beryllia, magnesia, zirconia, thoria, molybdenum, and tungsten when fired for 2, 4, and 8 minutes under vacuum conditions, using 100 °C. increments, in the temperature range 1500° to 2300°C. Temperatures at which instability of surface‐to‐surface contact was observed for the twenty‐one possible binary systems of the foregoing substances are also described for identical conditions of testing.
