Extraction of potassium from the feldspar was proposed for agricultural application. Potassium perchlorate has very little solubility in water; it is necessary to alter the insoluble salt into water-soluble salt of potassium. Therefore, potassium perchlorate was subjected to thermal decomposition at temperature around 600 °C in the furnace for

Potassium is a chemical element with the symbol K (from Neo-Latin kalium) and atomic number 19. Potassium is a silvery-white metal that is soft enough to be cut with a knife with little force. Potassium metal reacts rapidly with atmospheric oxygen to form flaky white potassium peroxide in only seconds of exposure. It was first isolated from potash, the ashes of plants, from which its name derives.
