Structural and Spectral Studies of ZnKPO4.6H2O Crystals

Zinc Potassium Phosphate Hexahydrate (ZPPH) is analogous to naturally occurring struvite. ZPPH crystals are grown by slow evaporation technique. These crystals are characterised by x-ray and infrared studies. Powder x-ray pattern indicates the orthorhombic crystal structure analogous to struvite with unit cell parameters a = 5.964, b= 5.808 and c= 12.495 Å. Infrared spectrum is characteristic of H2O and PO43- radicals.

Keywords: powder x-ray, IR, orthorhombic, zinc potassium phosphate hexahydrate (ZPPH), cell parameters
