  • Phosphorus Wikipedia

    Phosphate rock, which usually contains calcium phosphate, was first used in 1850 to make phosphorus, and following the introduction of the electric arc furnace by James Burgess Readman in 1888 (patented 1889), elemental phosphorus production switched from the bone-ash heating, to electric arc production from phosphate rock. After the depletion of world guano sources about the same time

  • Phosphate Rock an overview ScienceDirect Topics

    Phosphorus is prepared on an industrial scale by reduction of naturally occurring phosphates. Crushed phosphate rock, carbon, and silica (SiO2) are heated to 1200–1400 °C in an electric furnace from which phosphorus is removed by distillation.
