CRYSTALLIZATION PROCESS OF COBALT-CONTAINING LAYERED DOUBLE HYDROXIDES
Cobalt-containing layered double hydroxides with the structure of hydrotalcite were synthesized by coprecipitation of corresponding metal salt solutions at variable pH. The formation of the layered structure was shown to be observed at ambient temperature however ageing of the precipitates under solution at 98 °C during 48 hours led to an increase of the degree of crystallinity and ordering of brucite-like layers.
