ABSTRACT:
The present invention relates to the preparation of materials and more particularly to the preparation of tin oxide materials.
Thus, the present invention provides a process for the preparation of a tin oxide material by a gel precipitation process which includes contacting together a metal stannate, an organic gelling agent comprising a salt of a polycarboxylic acid and an acidic precipitating agent to form a gel precipitate.
The gel precipitate may be treated further to provide the tin oxide material.
The tin oxide material may be tin oxide as such, or a mixed oxide material containing tin oxide and an oxide of another element.
