Phosphoric acid was sometimes used instead of sulfuric acid. The process was first operated in Berlin in 1873 by the Schering Company. In the United Kingdom it was first operated in 1888 by B. Laporte Company. It was progressively replaced by the electrolytic process developed between 1908 and 1932. Also in the United Kingdom, Laporte Chemicals abandoned the barium process in 1950.
