Title:
COATED ALUMINUM OXIDE PARTICLES, METHOD FOR MANUFACTURING SAME, AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/136283
Kind Code:
A1
Abstract:
Provided are coated aluminum oxide particles having sufficient electric conductivity, and a method for manufacturing same. An antimony-doped tin oxide is contained in the surfaces of the aluminum oxide particles, such that the contained amount of an antimony component with respect to a tin component is 26-45 mass% when expressed as oxides as (Sb2O3/SnO2). To a dispersion liquid containing aluminum oxide particles and a solvent, an alkali and a hydrochloric acid solution, containing an antimony component and a tin component such that the components are contained at an amount of 26-45 mass% when expressed as oxides as (Sb2O3/SnO2), are mixed to cause a tin hydroxide that contains the antimony component to be deposited on the surfaces of the aluminum oxide particles. Then, the aluminum oxide particles are baked at a temperature of 400-800°C so as to be coated with an antimony-doped tin oxide.
