Abstract

"ARTIGO ABRASIVO". A presente invenção fornece um artigo abrasivo, em particular um disco de cortar, tendo uma mistura de grãos abrasivos modificados por óxido de terras raras e alfa alumina semeada ou grãos abrasivos nucleados de óxido de ferro. Preferivelmente, o óxido de terras raras está presente em um nível entre cerca de 0,1% em peso a 10% em peso do grão abrasivo, com base em uma base de óxido teórico. Em uma modalidade, os grãos abrasivos modificados de óxido de terras raras são bastões.
