We find ceramics wherever we go.
Without ceramic insulators, many household devices would not function.
Likewise, without insulators and safety devices made of technical ceramics, a reliable electricity supply would be unthinkable.
Ceramic substrates and parts are the basis for components and modules in all areas of electronics, while in machine and plant construction sliding and bearing elements provide low wear, corrosion-free function.
Ceramic construction and insulation materials are indispensable to the industrial furnaces used in high-temperature technology.
Even these few examples make clear that technical ceramics have an important role to play in today’s world.

	Alumina   Very high hardness and wear resistance Very high corrosion resistance High thermal stability Excellent dielectric properties
	Cordierite   Very slight thermal expansion extremely high resistance to thermal shocks
	Steatite Silicate based Cost-efficient Very good electric insulator Low thermal diffusivity
	Silicon carbide Low thermal expansion High thermal conductivity High hardness High elastic modulus
