Effects of two mixtures of kaolintalcbauxite and firing

The mixtures of kaolintalcbauxite which were fired at the range of 1300–1400 °C exhibited dielectric constant values varying between 203 and 28 along with dielectric loss tangent which varied between 01316 and 00002 at room temperature of the laboratory The two mixtures can be considered as promising materials for both ceramic and
