Values of dielectric constants were measured with mixtures of two organic-compound liquids. Sixty-seven combinations of two out of thirty different organic-compound liquids whose dielectric constants were ranging from about 2 to 40 were subjected to the measurement. Results of the measurement show that the dependence of the dielectric constant of the mixture liquid on its volume percent of the component liquid can be divided into six groups that can be expressed by six known theoretical relations. This will provide a guide for selecting appropriate combinations that have an acceptable linearity from application point of view over the entire range of the volume percent of composition. The temperature dependence of the dielectric constant ranging 5 to 10 at the room temperature was measured with thirty-one mixture liquids. The results are presented in a chart. This chart can be conveniently used in selecting an appropriate mixture liquid when the values of the dielectric constant and its temperature coefficient are specified.
It is intended that the data presented in this paper will provide useful information for the liquid-immersion method of measuring the dielectric constant of powder and grain materials.
