time-resolved neutron diffraction analyses of hydrothermal synthesis. Accordingly,
the hydrothermal reactors or cells are designed to suit such studies, which are very
popular among zeolites, clays, and other complex inorganic compounds

Figure 3.40
shows such a setup used for zeolite synthesis.
In recent years, high-pressure systems (about 40 kbar, temperature up to
1500
C) have been used in the synthesis of new compounds. Cylindrical platinum
