六水合磷酸铵镉（CAPH）类似于天然存在的鸟粪石。CAPH晶体采用缓慢蒸发法生长。这些晶体通过X射线、TG-DTA和XRD研究表征。粉末X-射线图显示了类似鸟粪石的斜方晶体结构。TG-DTA分析表明在113和391°C之间失去水合水（6 H 2 O）。后来，这种物质熔化，只有镉留在780°C左右。红外光谱是H2O、PO 43-和NH 4 +自由基的特征光谱.
Cadmium Ammonium Phosphate Hexahydrate (CAPH) is analogous to naturally occurring struvite. CAPH crystals are grown by slow evaporation technique. These crystals are characterised by X-ray, TG-DTA and Infra-red studies. Powder X-ray pattern indicates the orthorhombic crystal structure analogous to struvite. TG-DTA analysis suggests loss of water of hydration (6H 2 O) between 113 and 391°C. Later the substance melts and only Cd remains around 780°C. Infra Red spectrum is characteristic of H 2 O, PO 4 3- and NH 4 + radicals.
