Chen Qianlin, a member of the National Committee of the Chinese People's Political Consultative Conference (CPPCC) and dean of the Advanced Technology Institute of Guizhou University, has been conducting field surveys at companies since Spring Festival to collect opinions for this year's CPPCC session.

Chen has been engaged in education and scientific research related to chemical materials for a long time. His research focuses on using yellow phosphorus to produce phosphorous new energy materials and setting standards for the production of cement clinker and sulfuric acid from phosphogypsum.

With the development of China's new energy vehicles, demand for phosphorous new energy materials such as lithium iron phosphate is increasing sharply, thus driving up the demand for iron phosphate.

At present, the phosphorus chemical industry mainly uses wet-process phosphoric acid to produce iron phosphate. The process is mature but produces a large amount of phosphogypsum discharge, has a low resource utilization rate, and produces low-quality iron phosphate.

To solve these problems, Chen suggests that yellow phosphorus should be allowed to be used in new production projects for ferric phosphate/ferromanganese phosphate, and existing production projects should be allowed to start technical transformation using yellow phosphorus.

Through these efforts, the quality and international competitiveness of China's ferric phosphate/ferromanganese phosphate materials will be improved, and high-quality development will be achieved in the phosphorus new energy material industry.
