Raney nickel
Since Raney is a registered trademark of W. R. Grace and Company, only those products produced by its Grace Division are properly called "Raney nickel". The more generic terms "skeletal catalyst" or "sponge-metal catalyst" may refer to catalysts with physical and chemical properties similar to those of Raney nickel. However, since the Grace company itself does not use any generic names for the catalysts it supplies, "Raney" may become generic under US trademark law.
