A process is described for producing crystalline copper aluminum borate by forming an aqueous composition comprising a volatile organic liquid having at least partial miscibility with water, a source of copper(II) ions, a source of alumina, and a source of boria at a pH in range from about 4 to about 12 to form a homogeneous gel, drying the gel to form a superficially dry solid, and calcining the dry solid at a sufficiently high temperature to form crystalline copper aluminum borate. Also described is a method for producing a copper aluminum borate precursor which when dried and/or calcined to a sufficiently high temperature forms crystalline copper aluminum borate.
