Preparation of dispersions and gels

The preparation of a dispersion comprises treating a chemical compound with a quaternary ammonium hydroxide so as to peptise the chemical compound to form a dispersion. The dispersion may be, for example, a suspension or a sol (i.e. a colloidal solution). The chemical compound may be, for example, a...

Zusammenfassung:	The preparation of a dispersion comprises treating a chemical compound with a quaternary ammonium hydroxide so as to peptise the chemical compound to form a dispersion. The dispersion may be, for example, a suspension or a sol (i.e. a colloidal solution). The chemical compound may be, for example, a hydrous metal oxide (e.g. hydrous stannic oxide). Mixed dispersions may be formed.
