The electrical response of hematitic sandstone samples was measured at different hematitic sandstone concentrations. The heterogeneity and randomness are a very big problem that control (the dominant) the electrical properties of the samples.Hematite is one of the most common minerals. The color of most red and brown rock, such as sandstone, is caused by small amounts of Hematite. It is also be responsible for the red color of many minerals. Non-crystalline forms of Hematite may be transformation s of the mineral Limonite that lost water, possibly due to heat. Chemical Formula. Fe2O3.Then, they showed frequency-dependent behavior at high frequencies. The stable behavior of electrical and dielectric properties of natural calcite and quartz could make them candidate materials to be used as high-voltage power insulators up to a temperature of 700 K.
