Raspite is a mineral, a lead tungstate; with the formula PbWO4. It forms yellow to yellowish brown monoclinic crystals.[2] It is the low temperature monoclinic dimorph of the tetragonal stolzite.[2][3]
It was discovered in 1897 at Broken Hill, New South Wales, Australia , it was named for Charles Rasp (1846–1907), German-Australian prospector, discoverer of the Broken Hill ore deposit.[4]
