WebThe jarosite group of compounds are yellow/brown clay like substances, both naturally occurring and synthetically produced in metallurgical processes. Jarosites have the structure MFe 3(SO 4) 2(OH) 6, where M can be numerous elements or compounds, most often potassium or sodium. The term jarosite WebPotassium jarosite is the most stable of the alkali jarosites and the stability falls systematically for lighter or heavier congeners; ammonium jarosite is slightly more stable than the sodium analogue. Complete solid solubility among the various alkali jarosite-type compounds was established.
WebA low concentration of potassium is needed for the potassium jarosite [6] formation, whereas a high concentration of sodium is required for the sodium jarosite [7]. Previous findings indicate that jarosite is formed by a single nucleation event followed by two independent stages of development, each with a different Avrami exponent [6].
