ABSTRACT:
The present invention concerns an improvement in the electric furnace process for making elemental phosphorus. The invention features the deliberate addition of an alkali to the burden or charge that is fed to the furnace. Several advantages are gained by the addition of an alkali: pollution is reduced by scavenging fluorine compounds, operating efficiencies are gained, and control over the process is simplified.
