METHOD FOR PRODUCING AN OXIDE OF ALUMINUM BASED CORUNDUM ABRASIVE GRAIN WITH INCREASED TENACITY AND USE THEREOF IN ABRASIVES

摘要

A method for the production of an oxide of aluminum based corundum abrasive having a titanium oxide content of less than 0.8 wt. %, wherein the oxide of aluminum is processed by means of a melt or sintering process to form a compact base body for abrasive grains; the base body for abrasive grains is comminuted; the abrasive grain strip thus obtained is graded and the manufactured grain or the graded strip of abrasive grain is subsequently post-treated thermally at temperatures of 800 -1500 °C in order to increase the tenacity thereof. The invention also relates to the use of the corundum abrasive grain in abrasives. .
