Steatite ceramic is used extensively for insulation in the electrical and electronic industries. It is a lower cost material than alumina but has excellent electrical resistance properties (which are retained at high temperatures), along with moderate mechanical strength.
What is steatite material?
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.
What materials make up ceramic?
Ceramics are generally made by taking mixtures of clay, earthen elements, powders, and water and shaping them into desired forms. Once the ceramic has been shaped, it is fired in a high temperature oven known as a kiln. Often, ceramics are covered in decorative, waterproof, paint-like substances known as glazes.
