Abstract
An abrasive particle having an irregular surface, wherein the surface roughness of the particle is less than about 0.95. A method for producing abrasive particles having a unique surface morphology including providing a plurality of abrasive particles; providing a plurality of metal particles; mixing the abrasive particles and the metal particles to form a mixture; compressing the mixture to form a compressed mixture; heating the compressed mixture; and recovering modified abrasive particles.
Claims14
A method for producing abrasive particles having an irregular surface comprising the steps of:
- providing a plurality of abrasive particles;
- providing a plurality of metal particles;
- mixing said abrasive particles and said metal particles to form a mixture;
- compressing said mixture to form a compressed mixture;
- heating said compressed mixture;
- modifying a surface of the particles;
- and
- recovering the modified abrasive particles, wherein a surface roughness of the modified abrasive particle is less than about 0.95 and the sphericity of said particle is less than about 0.70, each particle having one or more spikes and pits.
