Microrose (1) / Metal-pyrophosphates (2)

During the preparation of colloidal metal-phosphate salts the synthesis sometimes fails and the resulting particles are far too large to be colloids: an ugly system to the colloid chemist’s eye. However, when looking at the particles with an electron microscope we receive a small present: the particles have by themselves formed all kinds of beautiful structures depending on system composition. In a way, the ‘failed’ particles are more beautiful than the successfully prepared ones.
