Meaning of "ullmannite" in English

Ullmannite is a rare sulfide mineral composed predominantly of nickel and antimony, often with trace amounts of arsenic coexisting in the structure. It typically appears in a metallic form, exhibiting a steel-gray to black coloration, with possible hints of tarnish displaying a reddish or purplish hue. Ullmannite is named after the German chemist Friedrich Ullmann. It can be found primarily in hydrothermal deposits or as a minor constituent in nickel-bearing ores. Its unusual chemical composition and metallic luster make it of interest to both mineral collectors and geologists.
