A study of the texture and structure of Raney nickel

Abstract

The texture of Raney nickel was simultaneously approached by nitrogen adsorption, magnetic measurements, X-ray diffraction line-broadening, X-ray small angle scattering and electron microscopy. The grain of Raney nickel, with a size larger than 1000 Å, takes the form of a collection of crystallites ranging in size from 25 to 150 Å, held together in the shape of a sponge. The average pore radius is 34 Å, but individual elements possessing an average radius of 7 to 8 Å also appear. Electron and X-ray diffraction patterns correspond to face-centered cubic nickel.
