Abstract
Official abstract text for this publication.
The present invention provides a globular-shaped metal oxide powder with excellent thermal insulation performance and reduced bulk density, and a method of manufacture thereof, wherein the metal oxide powder has globular independent particles as the main component, and has BET specific surface area of 400 to 1000 m 2 /g, BJH pore volume of 2 to 8 mL/g, and oil absorption of no less than 250 mL/100g. The present invention also provides a method for manufacturing the hollow and globular shaped metal oxide powder including the step of forming an O/W/O emulsion.
First claim
Opening claim text (preview).
The invention claimed is: 1. A metal oxide powder comprising globular independent particles as main component, said metal oxide powder having: BET specific surface area of 400 to 1000 m 2 /g; BJH pore volume of 2 to 8 mL/g; and oil absorption measured by refined linseed oil method specified in JIS K5101-13-1 of no less than 250 mL/100 g, wherein each said independent particle includes therein one or more hollow space having a size of 0.5 to 15 μm; and wherein the metal…
