The urea decomposition property at high temperature has been used to control the pH value in the synthesis of layer compounds. The hydrotalcites of Mg-Al and Ni-Al with high crystallinity were synthesized by using this property.
- Hydrotalcite-like compound,
- urea decomposition,
- control of pH value
