Cobalt melting point6/29/2023 ![]() Most of the cobalt that is mined is used in superalloys which are very resistant to corrosion and are stable at high temperatures.Ĭobalt is also used as a blue coloring agent in paints, inks, glass, ceramics, and even cosmetics. The majority of cobalt is mined in Africa and is a byproduct of the mining of other metals including nickel, copper, silver, lead, and iron. Cobalt ores include erythrite, cobaltite, skutterudite, and glaucodot. It forms many compounds with other elements such as cobalt(II) oxide, cobalt(II) fluoride, and cobalt sulfide.Ĭobalt is not found as a free element, but is found in minerals in the Earth's crust. It reacts slowly with oxygen from the air. It can be easily magnetized and maintains its magnetism at high temperatures.Ĭobalt is only somewhat reactive. It is one of the few elements that is naturally magnetic. Under standard conditions cobalt is a hard, brittle metal with a bluish-white color. Cobalt atoms have 27 electrons and 27 protons with 32 neutrons in the most abundant isotope. is the first element in the ninth column of the periodic table.
