Document Type and Number:
WIPO Patent Application WO/2021/200486
Kind Code:
A1
Abstract:
The carbon-containing alumina powder of the present invention comprises carbon-containing alumina particles in which the projected area-equivalent circle diameter obtained by microscopy is 1-100 μm, wherein the carbon-containing alumina particles have an average sphericity of 0.85 or more and a specific surface area of 0.05 m2/g or more and 1.0 m2/g or less, and the ratio B/A of carbon content ratio B to carbon content ratio A in the carbon-containing alumina powder calculated using a specific measurement method is 0.20-0.90.
