Abstract

Moisture formation in urea calcium phosphate fertilizer were synthesized by using ball milling technique. Prolonged milling time can cause moisture formation in the presence of water that makes the mixture wet and sticky. In this study is to find the best optimum milling time to avoid moisture formation of urea compound and to investigate the moisture formed in the compound during milling at 2 to 14 minutes. Physical observation and sample characterization were analyzed by X-Ray Diffraction (XRD), Thermal Gravimetric Analysis (TGA), and Fourier Transform Infrared (FT-IR) spectroscopy. It is observed that the product is in solid powder form at 2 minutes and become clumpier from 4 to 12 minutes. However, wet and sticky mixture was observed after milling for 14 minutes.
