Abstract:
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 m2/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.
