Method for preparing aluminum oxide-based composite material complex-shape abrasive particles through spray pyrolysis deposition
A method for preparing aluminum oxide-based composite material abrasive particles with complex shapes through spray pyrolysis deposition comprises preparation of a precursor solution, spray pyrolysis deposition and pressure sintering, and the preparation of the precursor solution is that aluminum salt and the like are prepared into a mixture; the precursor solution is decomposed and deposited into a mold with a complex shape at a high temperature through spray pyrolysis deposition, and an aluminum oxide pressed blank with a complex shape is obtained; and performing high-temperature purification and pressure sintering on the obtained complex-shaped aluminum oxide pressed blank to finally obtain a nearly fully-dense nano or superfine aluminum oxide-based composite material complex-shaped grinding material. According to the method, large-batch, low-cost, high-stability and high-quality preparation of the complex aluminum oxide abrasive particles can be realized.
