Cobalt powder is a scarce strategic metal in the world, appearing as a gray irregular powder, soluble in acid, and magnetic. The cobalt content in the Earth’s crust is 0.018%, and the proven terrestrial cobalt reserves are over 10 million tons. However, there are not many independently formed cobalt deposits, which usually exist in useful minerals such as nickel, copper, iron, and silver in the form of associated elements. They are recovered as by-products and are one of the key raw materials for superhard alloy materials such as hard alloys and artificial diamond tools.

Application areas of cobalt powder
Battery industry: The application of cobalt in batteries is remarkable, especially the widespread use of lithium-ion batteries, which greatly increases the amount of cobalt used. The application prospects of nano cobalt powder are also very broad in daily life and high-tech fields. According to reports, adding an appropriate amount of nano cobalt powder to solar cells can produce a new type of solar cell with higher photoelectric conversion efficiency, which can be used normally even in rainy weather.

In the field of ceramics, ultrafine cobalt powder can significantly improve the microstructure of ceramic materials and optimize their properties. Conventional ceramics are made by fusing various particles together under high temperature and pressure. After compressing ultrafine cobalt powder into blocks, due to the high energy at the interface between particles, sintering at lower temperatures can achieve densification, and the performance is excellent. Therefore, it is particularly suitable for the preparation of electronic ceramics.

Electronic device industry: Ultra fine powders have high specific surface area, high activity, and special physical properties, making them highly sensitive to external environments such as temperature, light, moisture, etc. Changes in the external environment can quickly cause changes in their surface or surface ion valence state and electron transport, leading to significant changes in their resistance. The unique properties of ultrafine powders make them one of the most promising materials for sensors, which can develop sensors for various purposes with fast reaction speed, high sensitivity, and good selectivity.
