Abstract: <FONT face=Verdana>Sodium monofluorophosphate is a high value-added fine phosphate-containing complex salt,which has very wide applications.It is mainly used as toothpaste additives，and also used as antiseptics,germicides,food additives and corrosion inhibitors etc..Combining with the present situation of inorganic fluoride chemical industry in China,the rationality of developrment of sodium monofluorophosphate production was illuminated and main production technologies,such as fusion method,liquid phase neutralizing method,and gas phase fluorizating method,at home and abroad were especially introduced.Fusion method was a traditional and widely used method,which was introduced in detail from the angle of technical process,reactive equipment,and technology improvement.Meanwhile,technical process and characteristics of other methods were also briefly introduced.Through the analysis on the existing problems of those technologies,proposals for development direction in future were put forward.</FONT>
