Abstract: Aluminum phosphate is a widely used material and has good application prospect in building materials,refractory materials,and chemical industry etc..Its preparation methods mainly include liquid phase synthesis,solid phase synthesis,and gas phase synthesis.And these methods were introduced in detail.At the same time,application of aluminum phosphate as adhesive,molecular sieve,special cement,and high temperature oxidation resistant coatings were expounded.Then,pointed that the development of aluminum phosphate adhesive should be environmental-friendly,functional,and special;synthesis process optimization,cost reduction as well as reasonable modification is the future research trend of aluminum phosphate molecular sieve;aluminum phosphate cement researches should be focused on adhesive strength improvement and brittle reduction;in the field of high temperature oxidation resistance,aluminum phosphate is a promising material.
