Calamine (mineral) Calamine (mineral) Calamine is a historic name for an ore of zinc. The name "calamine" was derived from "lapis calaminaris", a Latin corruption of Greek "cadmia (καδμία)", the old name for zinc ores in general. The name of the Belgian town of Kelmis, "La Calamine" in French, which was home to a zinc mine, comes from that. In the 18th and 19th centuries large ore mines could be found near the German village of Breinigerberg. During the early 19th century it was discovered that what had been thought to be one ore was actually two distinct minerals: Although chemically and
Bioabsorbable metallic glass numerous ternary alloys along the 350 °C isotherm of the Mg-Zn-Ca system. Ternary Ca-Mg-Zn bulk metallic glasses were also discovered in 2005. Similar to the Mg-Zn-Ca, these two amorphous alloys are both bioresorbable metallic glasses and are based on the same "Mg-Zn-Ca ternary system". The elements are displayed in order of decreasing atomic concentration. Hence, the distinction between these two metallic glasses lies in their most dominant element, namely Ca and Mg. These Ca-based bulk glassy alloys had compositions of CaMgZn, CaMgZn, and CaMgZn, where X = 0, 5 and 10; Y = 0, 5, 7.5, 10, and 15; and
