Abstract: An aluminum phosphate composition comprising aluminum phosphate, aluminum polyphosphate, aluminum metaphosphate, or a mixture thereof. The composisition 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.

Abstract translation: 一种磷酸铝组合物，其包含磷酸铝，多磷酸铝，偏磷酸铝，或其混合物。 该组合物的特征可以在于粉末形式时具有颗粒，其中一些颗粒每个颗粒具有至少一个或多个空隙。 此外，组合物的特征在于在差示扫描量热法中在约90摄氏度至约250摄氏度之间显示出两个吸热峰。 组合物的特征还在于，当其为粉末形式时，其具有至少0.025克/ 1.0克水的分散性。 该组合物通过包括使磷酸与硫酸铝和碱性溶液接触以制备磷酸铝基产物的方法制备; 并且任选地在升高的温度下煅烧磷酸铝，多磷酸盐或偏磷酸盐基产品。 该组合物可用于涂料和作为二氧化钛的替代物。
