The preparation of ceramic nickel metal microcompostes using an ammonium soap solution-based method
- Southwest State Univ., Marshall, MN (United States)
Robinson and Maginnis have developed a process for the preparation of metal ceramic composites using an ammonium soap solution-based route. Their work focused on the preparation of silver/YBa{sub 2}Cu{sub 3}O{sub 7-x} composites. We have extended their work to prepare nickel ceramic microcomposites. In this method, an ammonium soap of 2-ethylhexanoate is used to prepare a nickel metallorganic in solution that is rapidly gelled or precipitated around a suspended and dispersed ceramic. This is followed by a low-temperature heat treatment in hydrogen to produce the desired composite. By varying the heat treatment, the composite can be altered from metal-coated ceramic grains to finely dispersed metal in a ceramic matrix. The experimental preparation of this material will be presented along with optical micrographs and spectroscopic data.
