Abstract

"GRãOS ABRASIVOS à BASE DE OXINITRETO DE ALUMìNIO". A presente invenção refere-se a grãos abrasivos à base de oxinitreto de alumínio, com um teor equivalente em AIN, medido em um diagrama pseudobinário Al~ 2~O~ 3~-AIN, compreendido entre 2,5% e 7,5% em peso e, de preferência, entre 3 e 6% e uma estrutura constituída majoritariamente de AION <sym><39> e de AION <sym>. Esses grãos abrasivos são utilizados notadamente para a fabricação de mós de retificação, de telas e papéis abrasivos, de pasta de polir e de abrasivos projetados.
