CERAMICS
Originally, ceramics referred to everyday objects made of clay. Today, ceramics is the generic term for inorganic, non-metallic materials that are characterized by a wide range of properties.
Properties
Ceramics can be very hard and resistant to heat or corrosion. Some of them conduct electricity, others are insulating. The properties depend on chemical composition and production.
Production
Very fine powders are pressed, sprayed or, after being mixed with liquids, poured into shape, then dried and heated. Heating, also called sintering, and powder control the properties.
Application
The spectrum ranges from tableware or prostheses, electronic components and cutting tools for mechanical engeneering to heat protection in air and space travel.
Ancient Beauty
Ceramics are considered to be the first material created by humans. At no less than 25,000 years of age, the "Venus of Dolní Věstonice" is the oldest known ceramic figure.
What is Jülich doing?
Jülich develops, characterizes and tests ceramic materials and components for use in batteries and fuel cells, as filter membranes or heat protection in turbines, for example.
