Tennessee Valley Authority production. Elemental phosphorus. A stack in the TVA phosphoric acid plant in the Muscle Shoals area. Phosphoric acid is produced in conjunction with the making of elemental phosphorus. The phosphorus, used in the manufacture of incendiary bombs and shells and of material for "smoke," is produced by smelting phosphate rock, coke and silica together in electric furnaces and condensing the resulting phosphorus gases. When surplus phosphorus is available it is converted into highly concentrated phosphatic fertilizer, much of which is shipped abroad under provisions of the Lend-Lease Bill
