Industrial applications
Polishing and grinding
With a Mohs hardness of 9, aluminum oxide is used in many polishing agents for industrial and consumer uses. Because polishing performance differs depending on the substrate, our Martoxid® aluminum oxides vary in friability, surface area, degree of calcination and particle size distribution. Possible surfaces include soft metals, hard metals, painted surfaces, plastics and silicon wafers.

Technical ceramics
Technical ceramics made of aluminum oxides provide high mechanical strength and extreme hardness, as well as excellent resistance to wear, temperature and corrosion. They deliver thermal conductivity and good electrical insulation for engineered ceramics, electronic components, anti-wear components and other high-performance applications. Martoxid® superground, ground and unground technical ceramics grades and ready-to press KMS grades provide highest purity, low soda content, good processability and excellent sintering behavior for engineering of ceramic bodies in most demanding applications.

Gas and liquid purification
Compalox® activated aluminum oxides are the preferred material to extract impurities from liquids because of their highly adsorptive properties. Compalox® is an indispensable product during H₂O₂ processing.
Adsorption: Huber Advanced Materials’ activated alumina excel as adsorbents for drinking water purification, chemical processing, polymer production, and oil & gas processing. Compalox® activated alumina is a versatile adsorbent in a very broad variety of applications.
Chromatography: Martoxid AN/I activated alumina powder serves as an adsorbent in chromatography, effectively separating compounds based on polarity, thus ensuring efficient purification and analysis of chemical mixtures.
Filtration: Martoxid calcined alumina is used as a filter support structure or active filter layer due to its tunable porosity and mechanical strength, effectively removing impurities from liquids and gases.
Catalysts and Catalyst Carriers
Due to their high surface area, tunable porosity, mechanical strength, chemical inertness, and extreme temperature stability, Compalox activated alumina and Martoxid calcined alumina stand out as catalysts and catalyst carriers, enhancing efficiency and stability in various chemical processes.
Refractories
Superground Martoxid® aluminum oxides from Huber Advanced Materials excel as high-temperature resistant binding systems in demanding refractory applications. They match or exceed customer requirements for high temperature resistance, mechanical stability and processing characteristics while offering superior economics compared to silicon carbide, white fused alumina and tabular alumina.
Coatings
Pergopak® matting and effect agent grades provide a high-performance balance of matting, clarity, rheology and abrasion resistance along with a pleasant feel compared to that of matting agents alone. These organic thermoset polymethyl urea resins (PMUs) allow the creation of surface properties and visual and physical effects that cannot be achieved with standard matting agents like silicas or waxes.
