Document Type and Number:
WIPO Patent Application WO/2022/114179
Kind Code:
A1
Abstract:
Provided is zinc oxide powder in which the BET specific surface area is 8 m2/g to 65 m2/g, the apparent specific volume measured by a loose packing method is 1.0 mL/g to 7.5 mL/g, and the value obtained by dividing the apparent specific volume (mL/g) measured by the loose packing method by the apparent specific volume (mL/g) measured by a tapping method (apparent specific volume measured by loose packing method/apparent specific volume measured by tapping method) is 1.50 to 2.50.
