Abstract:

After more than 60 years of development,phosphorus chemical industry in our country has experienced from scratch and from weak to strong.The technology of producing high concentration phosphate fertilizer from medium and low grade phosphate,refining wet process phosphoric acid,producing feed grade calcium hydrogen phosphate and industrial grade ammonium phosphate by wet process has laid the foundation for the development of phosphorus chemical industry in China and also caused the industry overcapacity.The recent development of new products such as ammonium polyphosphate,potassium dihydrogen phosphate,phosphorous series flame retardant materials,battery-grade ammonium dihydrogen phosphate,lithium iron phosphate and lithium hexafluorophosphate indicates that the phosphorous chemical industry is transforming from extensive resource and environment products to fine phosphorous chemical products with high added value.

Key words: phosphorus chemical industry, technology, development course, development trend
