Novel materials from Feldspar as clay material and KH2PO4 (KHP) are prepared by grinding in a planetary ball mill in a mechanochemical process, one of the most effective ways to synthesize slow-release fertilizers. In two paths, tests were carried out with (3) weight ratio of Feldspar: KH2PO4 contents, at mill rotational speeds ranging from 200 to 700 rpm rotational speeds for two hours, and at milling times ranging from 1h, 2h, and 3h to evaluate the incorporation of KH2PO4 and liberation of K+ and PO43- ions into solution. To study the synthesized samples, Fourier transforms infrared spectrometry (FTIR), X-ray diffraction (XRD), thermal gravimetric analysis (TGA), and ion chromatography (IC) were used. The results confirmed that the mechanochemistry process is a sustainable chemistry method to produce amorphous Feldspars containing KH2PO4. After dispersing Feldspar and KH2PO4 in water for 24 hours, K+ and PO43- ions were measured. Based on these studies, it has been demonstrated that intercalated Feldspar could function as a carrier of K+ ions and release PO43- ions as a slow fertilizer.
