Mica is one of the oldest dielectric mineralmaterials used in capacitor construction, with very stable electrically, mechanically and chemically. It has a dielectric constant in the range 5–7. Natural mica contains many other materials including, iron, sodium, ferric oxide, and lithium. Because of the variability in composition of natural mica, mica destined for use in capacitors must be carefully inspected and classified, which adds to the manufacturing cost.
