A bstract A number of steatite ceramics were prepared under carefully controlled conditions, and their dielectric losses and direct‐current resistances were measured at elevated temperatures. It was found that variations of the ratio of talc to kaolin within certain limits had little effect on the dielectric properties. These properties, however, were changed to a considerable extent by varying the amounts, proportions, and kinds of alkaline earth oxides added as fluxes. The data indicate also that the conditions in a ceramic favorable to a high specific resistance are not necessarily those favorable to a low dielectric loss.
