ABRASIVE PARTICLE AND ITS MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide an abrasive particle capable of precisely abrading an object of abrasion with a high abrasive force, and a manufacturing method thereof. SOLUTION: The abrasive particle is composed of a mother particle and plural child particles adhered and fixed to the surface of the mother particle. As the mother particle, an elastic, spherical polymer particle having an average particle size of 1-100μm is employed. As the child particles, hard particles having an average particle size 1/500 to 1/10 as large as that of the mother particle are employed.
