Calamine the World Health Organization's List of Essential Medicines for being one of the most effective and safe medicines needed in a health system. Calamine is available over the counter as a generic medication. The wholesale cost in the developing world is about US$0.25–3.85 per 100-ml bottle. In the United Kingdom, it costs the National Health Service about £0.44. Calamine is used to treat itchiness. This includes from sunburn, insect bite, or other mild skin conditions. Calamine is mixed with either zinc oxide (ZnO) with about 0.5% ferric oxide (FeO) or a zinc carbonate compound. Calamine lotion is a component of
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
