    摘要： Provided is a freely flowing particulate fertilizer essentially consisting of potassium phosphate of the formula K3H3(PO4)2 and of less than 8 wt % water. The stable and not caking fertilizer is characterized by an XRD signal corresponding to 2-theta of about 70°. An economic process for making the fertilizer is also provided consisting in reacting KOH and monopotassium phosphate (KH2PO4) in water, heating the mixture under vacuum and cooling it down, thereby obtaining the particulate fertilizer.

    摘要翻译： 提供了一种自由流动的颗粒肥料，其基本上由式K 3 H 3（PO 4）2的磷酸钾和小于8重量％的水组成。 稳定和不结块肥料的特征在于对应于约70°的2-θ的XRD信号。 还提供了一种用于制备肥料的经济方法，其包括将KOH和磷酸一钾（KH 2 PO 4）在水中反应，在真空下加热混合物并冷却，从而获得颗粒状肥料。
