Patent ID: 8753601

Claim:
A metal salt consisting of a cationic metal and an anionic group, wherein the cationic metal is any metal cation, wherein the anionic group is selected from the group consisting of phosphates, borates, silicates, sulfates, carbonates, hydroxides, fluorides and mixtures thereof, wherein the metal salt is obtained by (a) forming a mixture of at least the metal source of the cationic metal which is a metal carboxylate with a mean carbon number per carboxylate group of at least 3 and at least one anionic source of the anion group into droplets, and (b) oxidizing said droplets in a high temperature environment in a range of 1200 to 2600° C., wherein the metal salt releases less than 5 wt % water upon heating to 900° C. at a heating rate of 10° C. per minute; and wherein the BET equivalent diameter is in the range of 5 to 200 nm.
