The preparation of ceramic/cobalt metal microcomposite using an ammonium soal solution based method
- Southwest State Univ., Marshall, MN (United States)
A process for the preparation of transition metal/ceramic composites has been developed by Robinson and Maginnis. Their work focused on the preparation of silver/YBa{sub 2}Cu{sub 3}Cr{sub 7-x} composite. We have extended their work to prepare cobalt ceramic microcomposites. In this method, an ammonium soap of 2-ethylhexanoate is used to prepare a cobalt metallorganic in solution that is rapidly gelled or precipitated around a suspended and dispersed ceramic. This step is followed by a low-temperature heat treatment in hydrogen to produce the desired composite. Depending on the heat treatment, the composite can be varied from metal coated ceramic gains to finely dispersed metal in a ceramic matrix. System specific schemes for the preparation of cobalt metal/ceramics will be presented.
