Dielectric ceramics are widely used in electrical and electronic engineering, in holders for resistors and thermocouples and in other insulating components. They also have numerous applications in the field of thermal insulation: thanks to their capacity to operate at high temperatures and to resist thermal shocks, they are ideal for applications that require effective heat insulation. In addition, they are utilised for the manufacture of coverings and components that must be able to resist high temperatures and aggressive environments.
