683Iron Oxide Pigments By Henry E. Stipp 1 Sales of finished iron oxide pigments in 1972 increased to record levels as the result of a rapidly expanding business cycle. Demand for iron oxide pigments, especially manufactured yellow, was very strong. Increased utilization of yellow iron oxide pigment was attributed to its application in paint formulations to replace lead compounds such as lead chromate, or chrome yellow. Paint containing lead concentrations greater than 0.06% lead has been banned for use in household interiors after December 31, 1973, by the U.S. Food and Drug Administration. Although imports of iron oxide pigments increased substantially, they were not sufficient ' to satisfy the strong domestic demand. Imports of iron oxide pigments were curtailed by the strong economic expansion that occurred in West European countries in 1972, and by *the effects of dollar devaluation and U.S. price controls. Normally, imports supplement domestic production of iron oxide pigments and supply a significant part of the domestic market. DOMESTIC PRODUCTION Production of finished iron oxide pigments, as indicated by sales in 1972, increased 35.9% to a record 174,392 short tons. The value of finished iron oxide pigments in 1972 increased 30% to $40.3 million. Yellow iron oxide recorded the greatest percentage increase among the manufactured varieties, and metallic brown oxide showed the largest increase among the natural iron oxide colors. Twelve companies operated 18 plants in nine States in 1972. Pfizer, Inc. was the major producer, with plants in California, Illinois, and Pennsylvania. Production of crude iron oxide pigments decreased substantially for the fourth con- secutive year. Figures for production and sales wete withheld in 1972 to avoid disclosing company confidential data. Five companies operating mines or plants in five States reported production of crude iron oxide pigments. The Cleveland-Cliffs Iron Co. produced the largest quantity from mines in Michigan. Expansion of facilities by Pfizer, Inc. in Illinois and California was completed by August, and supplies of finished iron oxide pigments were expected to increase sub. stantially by yearend. 1 Physical scientist, Division of Ferrous Metals.
