Heat-resistant aluminum hydroxide and method for preparation thereof

摘要

A heat-resistant aluminum hydroxide which is prepared by subjecting a mixture of aluminum hydroxide with a reaction retardant for retarding the conversion aluminum hydroxide to boehmite, as a raw material, to the hydrothermal treatment or to pressurization and heating in a steam atmosphere; and a method for preparing a heat-resistant aluminum hydroxide which comprises subjecting a mixture of aluminum hydroxide with a reaction retardant for retarding the conversion aluminum hydroxide to boehmite as a raw material to the hydrothermal treatment, or to pressurization and heating in a steam atmosphere.
