摘要： A preparation method for a water-insoluble crystal form ammonium polyphosphate includes conveying crystal H-type phosphorus pentoxide and diammonium phosphate at a molar ratio of 1:1-1.5 into a malaxator with twin screws, and injecting ammonia gas for 3-40 minutes into the malaxator at 20-25 m3/h while preheating the material at a temperature between 100° C. and 300° C. Therafter one injects ammonia gas again at 8-15 m3/h for 4-8 hours. The resulting material is transferred to another sealed container and stirred while coupling agent is added. Stirring continues until the material drops below 60° C., the material then being transferred into organic solvent for washing for 30-50 minutes. Thereafter the material is first filter pressed, then subjected to low temperature drying, and then sieved to obtain the final product.

摘要： An aluminum phosphate composition comprising aluminum phosphate, aluminum polyphosphate, aluminum metaphosphate, or a mixture thereof. The composition may be characterized by, when in powder form, having particles wherein some of the particles have at least one or more voids per particle. In addition, the composition is characterized by exhibiting two endothermic peaks in Differential Scanning Calorimetry between about 90 degrees to about 250 degrees Celsius. The composition is also characterized by, when in powder form, having a dispersibility of at least 0.025 grams per 1.0 gram of water. The composition is made by a process comprising contacting phosphoric acid with aluminum sulfate and an alkaline solution to produce an aluminum phosphate based product; and optionally calcining the aluminum phosphate, polyphosphate or metaphosphate based product at an elevated temperature. The composition is useful in paints and as a substitute for titanium dioxide.
