Melting point refers to a particular point of temperature at which the element start. ![]() Cobalt boiling point The boiling point of Cobalt is 2927 ☌ (3200 K, 5301 ☏). Melting point refers to a particular point of temperature at which the element start changing its state from solid to liquid. Brandt was attempting to prove that the ability of certain minerals to color glass blue was due to an unknown element and not to bismuth, as was commonly believed at the time. Quick links for Chemical Engineering exam. The melting point of Cobalt in different unit is 1495 C (1768 K, 2723 F). The melting point of Cobalt in different unit is 1495 ☌ (1768 K, 2723 ☏). It also can be used in dental care.Cobalt was discovered by Georg Brandt, a Swedish chemist, in 1739. It is also used in medicine, in electroplating, and in agriculture.Ĭobalt(II) fluoride, a compound with the formula CoF2, is used as a catalyst to alloy metals. cobalt, Co nickel, Ni copper, Cu The table shows the melting point and density of some transition elements, compared to three metals in the periodic table that are not transition elements. Cobalt can be used in the production of catalysts too. Cobalt had been used in imparting a blue color to glazes, glass, and ceramics. Cobalt compounds are used in the manufacture of porcelain enamels and batteries as well as in paints and inks. Cobalt blue has been used as a coloring agent in jewelry and Chinese porcelain. Cobalt is ductile and ferromagnetic, and has a metal. It also alloys with aluminum, platinum, iron, and nickel. Cobalt, chemical symbol Co, atomic number 27, melting point 1495, is a high melting point metal. Uses of CobaltĬobalt, a chemical element with the symbol Co, is used in making magnets. Due to its high strengths, the alloys of this metal are used in aircraft production, etc. Cobalt nitrate is the inorganic compound with the formula Co (NO 3) 2. With industrial purposes, cobalt is usually used in alloys with iron, nickel, and aluminum, to produce powerful magnets. If consumed in larger doses, cobalt is very carcinogenic. This element is crucial for all living organisms, but in micro doses. This element can be found in some minerals, as it was discovered that there are some cobalt deposits at the bottom of the oceans. 1660, and viscosity measurements by the oscillating crucible method at.
