<P>PROBLEM TO BE SOLVED: To provide nickel oxide powder suitable as the source material of a sintered body or a compacted body, having a porous fine structure with a high specific surface area, and having improved handling property and sintering property of the powder, and to provide its manufacturing method. <P>SOLUTION: The nickel oxide powder is manufactured by heat treating a nickel compound in the form of spheric particles by aggregation of primary particles in an oxidative atmosphere at 300 to 850°C. The nickel oxide powder is finely pulverized to have 0.1 to 50 μm average particle size, 0.05 to 0.50 cm<SP>3</SP>/g pore volume and 5 to 500 m<SP>2</SP>/g specific surface area. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
