Ceramics are the materials of the future, which were not widely used until late in the industrial age. A high-purity aluminum oxide was developed using the requirements profile for technical ceramics. The selection of the technical ceramic is made in close consultation with the users.

We constantly adapt our materials and products to the requirements of the market and of our customers on the basis of our many years of experience and in extremely close collaboration with leading manufacturers.

Quality improvement with ceramics

Wherever better wearing properties, higher chemical and temperature resistances, and improved electrical insulation are required, high-purity aluminum oxide — up to 99.7% — offers a professional solution.

Properties: • Good hardness and wear resistance • Extremely high corrosion resistance • High pressure and heat resistance • Aging resistance • High electric strength • Higher modulus of elasticity, so higher rigidity • Continuous temperature resistance to 1,700 °C • Low thermal expansion, low bulk density • Safe in contact with food and luxury products

Applications: • Chemical process technology, flue gas desulphurization technology • Pump construction for chemical operations, steelworks, and mines • Wire, cable, and paper manufacture • Forming technology • Size reduction technology • Metallurgical property determinations • Chemical laboratories • Armor for security technology • Semiconductor industry • Optoelectronics
