WebbFig. 3 shows SEM images of aggregated particles of the as-prepared product before and after washing. The presence of KCl in the product before washing was confirmed by EDX spectroscopy. As presented in Fig. 3, areas which exhibited signals of K α for K and Cl were assigned to KCl and areas which presented signals of K α for Mn, Fe, and K were … WebbPotassium oxide ( K 2 O) is an ionic compound of potassium and oxygen. It is a base. This pale yellow solid is the simplest oxide of potassium. It is a highly reactive compound that is rarely encountered. Some industrial materials, such as fertilizers and cements, are assayed assuming the percent composition that would be equivalent to K 2 O.
