Low-temperature decomposition of hydrated transition metal chlorides on hydrous gel substrates
- 240 Downloads
The thermal decomposition of hydrated transition metal chlorides of nickel, cobalt and iron was studied on a highly dispersed alumina gel substrate. The salts were found to decompose at significantly lower temperatures than the unsupported materials. This was found to be as a result of strongly bound surface water, characteristic of this type of hydrous alumina. The resulting decomposed products were highly homogeneous and reactive, forming ceramic precursor compounds at much lower temperatures than conventional methods.
