The crystal size may be controlled by selection of an appropriate crystallisation temperature.

The process provides a good crystal yield and a crystalline product having a uniform crystal structure and a narrow crystal size distribution.

The new SAPOs may have a small crystal size and may be synthesized from a single-phase synthesis solution.

The reduction of the crystal size allows to relax the selection rules on the of wave vector.

They can produce amorphous and flake graphites which are generally very heterogeneous in purity, in nature and in crystal size.
