First, the value of cobalt Cobalt is a trace element, but there are also corresponding mineral deposits. The ancient Greeks, the ancient Romans and the Tang Dynasty all had traces of using cobalt. This element was discovered by a Swedish chemist in 1753. 1874, people began to mine cobalt ore. Because this mineral deposit has a wide range of applications, there was a great demand for this element in that war-torn era, so many countries launched research on related projects, while China's research was relatively late, and it didn't achieve results until 1952.
Because this material is a material for making alloys, countries all over the world pay more attention to this material and invest a lot in its preparation. With the development of time, although this material is still a rare metal, but also because of the gradual increase of world output, the price has begun to decline gradually. Supply exceeds demand, and the price of cobalt has reached a relatively stable level, which will not change easily.
Second, industrial application This metal element has high heat resistance, is a very stable state in nature, is not easy to react, has very high hardness, corrosion resistance and magnetism, and can be used to prepare various alloys. Many materials that need heat resistance and corrosion resistance need his participation, such as gas turbine blades, jet engines and rocket engines. These all need this metal. In addition to preparing super alloys and anticorrosion alloys, cobalt is also used to make colored glass pigments and catalysts. Because his state is relatively stable, all kinds of pigments made are relatively stable and can be stored in the air for a long time. Moreover, cobalt compounds will have various colors, and these compounds also inherit the stability of cobalt and are very good as pigments or glass materials.
Third, the human body also has the medical application of this element. The biggest function of this element in human body is to promote hematopoiesis. It can help to produce erythropoietin and promote iron absorption. It can also participate in hematopoiesis through vitamin b 12, promote the release of red blood cells, and play a very important role in hematopoietic function.
