Electrocorundum white 23a,24a, 25a

White electrocorundum (brands: 25a, 24a, 23a, with the Al2O3 content of no more than 99%).Obtained from the alumina abrasive higher grade (25a), it possesses high hardness, strength, heat resistance, high brittleness and high cutting capacity, he has a slight number of impurities and more homogeneous in composition. It is more suitable for the abrasive paper and other products with an abrasive coating to produce a tool that is used for treatment of solid hardened steel, is also used for sanding.Since it is abrasive material, such properties as strength, hardness, brittleness and heat resistance, can regulated in process of its receipt. Introduction to the melt of various chemical elements that form solid solutions with it, get abrasive materials with desired properties, for example, chromic, Ti-electrocorundum etc.
