Abstract
The invention is related to a method of producing the Al(OH)3 fine powder whose Mass Mean Diameter (d50) is roughly ranged from 0.2 to 2.0 micrometers. The said manufacturing method is to introduce the nano or submicron Al(OH)3 fine powder to be used as the seed. By the temperature-controlled cooling crystal growth, filtration, water-cleaning, and dehydration process, the Al(OH)3 fine powder with high purity and low alkaline content can be obtained. The obtained powder can be applied as the flame-retarding agent filled in a plastic or rubber material, and more particularly used as the flame-retarding agent filled in the plastic substrate of a PCB.
