Mass production : A combination of mass spectrometry and dynamic light scattering has been used to monitor the nucleation and crystallization of all‐silica MFI and MEL zeolites from aqueous solution. The formation of the crystals involves hydrolysis of the alkoxysilane, oligomerization of the silicates, nucleation of amorphous Si colloids, and transformation of these colloids to crystal structures (see picture).
