The heat contents of three refractory substances, magnesium oxide, zirconium oxide, and zirconium silicate were measured relative to 0 C at 100degree intervals up to 900 C, using a precise drop calorimetric method. The magnesium oxide sample was of high purity. The other samples, however, were of relatively low purity. No attempt was made to correct heat-content and heat-capacity values for impurities. Specific heats were derived from and described by equations in calories per gram-deg C. The specific heats from these equations were compared with values from the literature.
