Steatite Ceramic Parts

Steatite ceramic part 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.

Steatite exhibits low contraction during firing, allowing us to produce components to precise tolerances. Both small and highly detailed shapes can be achieved using cost efficient production techniques, making steatite ceramic a good choice for the volume manufacture of insulating components.

Due to its excellent dielectric properties, steatite ceramic part has been used for many years in both large-scale electrical systems and electronics/domestic appliances. It has both a high volume resistivity and high dielectric strength, making it ideal for the production of electrically insulating components.

Steatite exhibits a low dielectric loss, allowing for their use for electrical insulation where radio and microwave frequencies are present. This low-loss property makes it the material of choice for insulation of broadcast antennae equipment (such as guy-strain insulators). Parts show good wear and corrosion resistance and can be supplied either glazed or unglazed.
