Item # L-3 Steatite (DC9), Steatite (1800ºF Low Porosity Ceramic - Cast & Extruded Parts)



L3 Steatite is ideal for high frequency, low loss, and high voltage electrical insulation. Our L-3 Steatite has good mechanical properties and low loss electrical qualities. It is ideal for resistor forms, igniters, standoffs, surge arrestors, coil forms, spacers, spark plugs, etc. Steatite is easily fabricated to close tolerances and is much less expensive than alumina ceramic insulators. Typical parts produced from Steatite are cores, tubes, rods, spacers, resistors, bushings, insulating washers, standoffs, and custom molded parts.
