Abstract
Pref of finely divided amorphous mixture of oxides of various elements. G6A. Solutions of mixtures of compounds of the elements Al, Si, Sn, Cu, ag, Y, Mn, rare-earths, Ti, Zr, Tl, V, Cr, Mo, W, U, Fe, Co, Ni; Zn in H2O (with or without the presence of acid or base) or C1-C20 organic solvent (preferred are dimethylformamide dimethylsulphoxide, N-methylpyrrolidone, dioxan etc.) are treated with a complex-forming agent (preferred are organic polycarboxylic acids or their derivatives). The solution is then concentrated, preferably within 20 mins., by heating to 20-90 degrees C, or by freeze- or spray-drying to a transparent solution of viscosity at least 200 cP, and finally in vacuum at 0-50 mm Hg. The residue is then decomposed at ca. 600 degrees C to give a finely-divided amorphous product, of apparent density 0.01 - 0.5, particle size 10 - 10,000 angstroms (or aggregates of specific surface above 0.1 m2/g), useful as catalsyts, pigments for paints and enamels, transparent ceramics, substances with special magnetic, dielectric, magnetooptic and piezoelectric properties, etc.
