Abstract: It is presented the current situation of phosphorus chemical industry in Guangxi Province，the deploitation of Chinese thermal process phosphoric acid in US market and the market dynamics of European phosphorus chemical industry.It is pointed out a few misunderstandings in China′s phosphorus chemical industrial development of phosphate fertilizers，feed grade calcium monophosphate，wet process purified acid，and polyphosphoric acid.Four suggestions for the development of Chinese phosphorus chemical industry were put forwarded:A） developing full water-soluble phosphorus fertilizers which apply to modernized agriculture；B）producing feed additives that meet the food grade standard；C）there is no need to spend too much for purifying phosphoric acid by wet process，instead we should find more ways to produce fertilizers directly using phosphoric acid by wet process；D）developing multiple application of polyphosphoric acid in different industries.
