Industrial Alumina Products
Huber Advanced Materials offers a range of Martoxid® calcined alumina grades specifically developed for technical ceramics applications. Martoxid® is characterised by high chemical purity, low alkali content (Na₂O < 0.1%), controlled crystal properties, fine particle size distribution, and consistent rheological behavior. These properties make it well-suited for ceramic components where high mechanical strength, hardness, wear resistance, thermal conductivity, and electrical insulation are required. Each Martoxid® grade is tailored to meet the specific demands of distinct application fields, supported by rigorous quality controls and careful manufacturing procedures that ensure low batch-to-batch variability. Huber Advanced Materials produces its full range of Martoxid® specialty oxides to a consistent standard, making it a reliable calcined alumina solution for technical ceramics producers.
