Nabaltec – Specialist for Special Oxides

Nabaltec manufactures, develops and distributes special oxides. This highly specialized product segment has been developed based on aluminium oxide. The company´s product range Specialty Alumina includes aluminum oxide for applications in refractory industry, technical ceramics, polishing agents and thermal management.


NABALOX Reactive Alumina is a proper way to reduce water demand of castables and, as an indirect consequence, to increase the apparent density of the same. The new generation of viscosity optimized reactive alumina allows the combination of both, lowest water demand and practice compatible free flowing consistency. With this innovative product group Nabaltec offers new solutions for the development of castables and monolithics with perfect rheological properties.

Technical Ceramics

With the GRANALOX and NABALOX grades, Nabaltec offers alumina based products of high quality, suitable for a wide diversity of shaping methods. The “ready-to-press” ceramic bodies, GRANALOX are formulated with all necessary inorganic and organic additives and can be directly used ‘as supplied’. Furthermore, we offer dedicated grades for a variety of forming methods in 3D-printing. Our grades can be used for processes such as stereo-lithography, binder jetting, fused filament manufacturing, etc.

Thermal Management

For gap fillers and Thermal Interface Materials (TIM) in the electronic industry Nabaltec AG has developed high performance fillers based on aluminium oxide NABALOX HC. Their optimized particle size distributions simultaneously allow high packaging densities (resulting in high thermal conductivity) and extremely low viscosity levels.


The NABALOX polishing oxide range offers a broad spectrum of soft and hard calcined aluminas for a variety of applications for industrial surface finishing. A multitude of NABALOX polishing aluminas are used for the production of polishing pastes and emulsions for almost any material group, such as metals, stone, plastics, car paints, semiconductors, special glasses and many others.
