Patent ID: 8877118

Claim:
A method of producing a Ni/zirconia-based porous body, comprising (a) mixing a zirconia raw material, nickel oxide, a thermally decomposable nickel salt selected from Ni(OCOCH 3 ) 2 , Ni(HCOO) 2 , Ni(C 5 H 7 O 2 ) 2 , NiCl 2 , [CH 3 (CH 2 ) 6 CO 2 ] 2 Ni, NiC 2 O 4 , Ni(ClO 4 ) 2 , NiSO 4 , hydrates thereof and mixtures of two or more thereof, and a binder, (b) forming the mixture into a green body, and heat treating the green body to remove decomposable materials from the green body, (c) sintering the heat-treated green body to obtain a sintered body, and (d) reducing the sintered body.
