Noble electrocorundum (white)

Noble electrocorundum, also known as white electrocorundum, is an abrasive raw material obtained synthetically by melting aluminum oxide. Noble electrocorundum is an artificial abrasive material characterized by the highest chemical purity among materials based on aluminum oxide Al2O3. Compared to ordinary electrocorundum, it is more homogeneous in terms of chemical composition, structure and properties.

Electrocorundum is an ecologically clean and very hard raw material resistant to aggressive chemical agents. Noble electrocorundum does not contain crystalline, chemically unbound silica (SiO2).

Strict control of the quality of raw materials and smelting parameters ensures the production of noble electrocorundum of high purity and high whiteness. Noble electrocorundum is iron-free and distributed in a narrow particle size distribution. The grain size of white aluminum oxide complies with FEPA (Federation of European Producers of Abrasives) standards.

Noble electrocorundum grains are more porous than ordinary electrocorundum.
