摘要

A method for the production of phosphates and / or phosphate-containing compounds, comprising the steps of:(a) heating of bone and / or fish bones or a composition of these components in the absence of oxygen at temperatures between 500°C. to 1100°C,(b) secondary combustion of the in step (a) resulting carbon under oxidizing conditions at temperatures between 500° to 1200°C.
