Steatite is a low cost material with high electrical resistance at high temperatures, good mechanical strength and a very low dielectric loss factor. Such properties make it ideal for high frequency, low loss, and high voltage insulation. Moreover, steatite is an excellent material for electrical engineering as it can be readily shape sintered into a wide variety of forms such as washers, bushings, resistor forms, spaces and beads.
Steatite has been used for many years in large-scale industrial systems, household electronic appliances, aerospace and automotive applications, and specialized eletro-technical instruments such as cathode-ray tubes.
