Aluminium oxides and aluminium hydrates as components of ceramics

Ceramics are inorganic, non-metallic materials and products that only acquire their final properties through the high-temperature process. All of us are familiar with the most diverse forms and objects of ceramics. The history of ceramics made of aluminium oxide goes back to a patent specification from 1928, in which the first production of spark plug insulators was described.


Our aluminium oxides named here and also aluminium hydroxides have proven themselves in the production of ceramics and also glazes.


One differentiates between

  • Structural ceramics

  • Wear resistant ceramics

  • Thermal ceramics

  • Dielectric ceramics

  • Chemical ceramics

  • Catalyst support

  • Filter ceramics

In addition to chemical purity, grain size distribution, the size of the primary crystal and the specific surface area are important parameters for ceramic production.


We offer ceramists a continuous and precisely controlled range of grain sizes.

Alumina with
Low Soda Content

Low soda alumina are used in the production of spark plugs or special structural ceramics.

Mixed oxides

Since some customers have approached us with the question of mixed oxides, we have included them in our range. Our mixed oxides were designed on the basis of a mixture of Al₂O₃ and ZrO₂. Materials with Al₂O₃ as the main component are called ZTA (Zirconia toughened Alumina) and with zirconia as the main component ATZ (Alumina toughened Zirconia). These compounds are characterised by the high strength and toughness of the zirconium oxide and the hardness and wear resistance of the Al₂O₃. These products can be used in the polishing sector or in special ceramics. Further products on request.
