ABSTRACT:
The present invention relates to the preparation of materials and finds application in the preparation of dispersions and gels.
The invention provides, in one aspect, a process for the preparation of a dispersion which comprises treating a chemical compound with a quaternary ammonium hydroxide so as to peptize 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 in accordance with the present invention.
