| dc.description.abstract | The mineral taranakite was obtained in reactions between samples of an Akaka soil and monopotassium phosphate solutions ranging from 0.2 to 0.6 molar, at pH values of the reacting system ranging from 2.3 to 2.9. Characteristics of the reaction products were compared with those of pure synthetic taranakite, using X-ray, chemical, optical, infrared absorption, and differential thermal techniques. The taranakite was essentially a potassium-aluminum-phosphate complex. There was no indication of isomorphous substitution of iron for aluminum. The molar ratios of K/P04 and Al/P04 of the reaction product were found to be 0.37 and 0.72 respectively. The taranakite was thought to be formed by precipitation of a soluble phospho-alumino complex anion together with potassium ions. The possibility is suggested of the formation of taranakite when soluble potassium and phosphate react with Hydrol Humic and Humic Latosols in the field. During the early stages of reaction, the reaction product is believed to be cryptocrystalline, but the size of crystals increases with time. | |
