NOVELTY - Forming a batch of coated abrasive particles comprises providing a dispersion of abrasive particles (1803) having an average particle size of less than or equal to 10 mu m in a bath, coating the abrasive particles in the bath with a coating material, applying ultrasonic energy to the bath and adjusting a power of the ultrasonic energy to form a batch of coated abrasive particles having a non-agglomeration factor (NAF) of at least 0.90.    USE - The method is useful for forming a batch of coated abrasive particles, which are useful in an article, preferably a fixed abrasive wire (all claimed) or a fixed diamond wire for slicing of silicon wafers for solar devices or sapphire wafers for LED applications.    ADVANTAGE - The coated abrasive particles facilitate the manufacturing of the abrasive article with improved kerf loss and high quality.    DETAILED DESCRIPTION - Forming a batch of coated abrasive particles comprises providing a dispersion of abrasive particles (1803) having an average particle size of less than or equal to 10 mu m in a bath, coating the abrasive particles in the bath with a coating material, applying ultrasonic energy to the bath and adjusting a power of the ultrasonic energy to form a batch of coated abrasive particles having a non-agglomeration factor (NAF) of at least 0.90. The non-agglomeration factor is defined as a ratio (D50sa/D50b), where D50b is the median particle size of the batch of coated abrasive particles and D50sa is the median particle size of the abrasive particles prior to coating. INDEPENDENT CLAIMS are included for:    (1) the batch of coated abrasive particles; and    (2) making an abrasive article, comprising providing a substrate (1801) and attaching the batch of coated abrasive particles to the substrate.
