Latest Patents

Wilhelm E Pavonet holds a patent for an iron oxide-based pigment and the process for preparing such a pigment. This invention involves an iron oxide pigment in alpha-Fe₂O₃ form, which contains a water-insoluble part obtained by calcination of basic iron sulfate and/or jarosite-based residues. The process includes calcining these materials at temperatures ranging from 600°C to 800°C for a duration of 2 to 240 minutes. This method allows for the incomplete decomposition of basic iron sulfates and/or jarosite, resulting in a calcined product with an iron-bonded sulfur content exceeding 0.6%. The not decomposed iron sulfates are then solubilized with other soluble sulfated metals, such as zinc sulfate, through lixiviation, followed by the separation of these water-soluble compounds.
