| 摘要 |
This invention applies to thermal spray coating and powder manufacturing of materials where non-nitrate precursors are required to obtain the desired coating and/or powder characteristics. In general, the most economical path in material synthesis involves the use of readily available metal sources consisting of nitrates or acetates. Some metallic sources exist only in nitrate form and do not have a liquid solvent soluble acetate form. Using this metal nitrate in a pyrolysis process produces fluffy powders that lead to porous and poor coatings, or fluffy powders that do not have the proper flowability. In this disclosure, the metal or metal oxide that offer only nitrate based precursor is replaced with a nanopowder of the metal or metal oxide as the feedstock source. The nanopowder is homogeneously dispersed as a suspension and mixed with the other solvent based solution precursors of the accompanying solutes to produce the desired composite metal oxide. |
