I believe everyone is no stranger to metal powders, but if the editor asks you what are the preparation methods? I believe there are many people who can’t answer. In order to let everyone know this product better, today I will talk about the preparation method of metal powder for everyone.

1, mechanical method

Mechanical method refers to a processing method that uses external mechanical force to break metal into powder of the required particle size. This method only changes the physical properties of the powder without affecting its chemical composition. Moreover, the operation method is simple, the output is large, and it is used in many places.

2, atomization method

The method of directly crushing the alloy powder to obtain the powder is the atomization method. From the perspective of production scale, this method is second only to the reduction method, and it is also the most widely used metal powder preparation method. The metal powder produced by the atomization method has the characteristics of high sphericity and low oxygen content.

3, reduction method

The 　　 reduction method is mainly used in the metallurgical industry. Its operation process is simple and the use cost is low, but its work efficiency is very high, which is very suitable for industrial production.

4, electrolysis method

The "electrolysis method" is a method in which metal powder is deposited on the cathode by electrolyzing molten salt or an aqueous solution of salt. Among the whole metal powder preparation methods, the electrolysis method has its place. Its production scale is second only to the reduction method in the physical and chemical methods. The purity of the powder produced by it is high, and the elemental powder can reach more than 99.7%. However, the electrolysis method consumes more electricity, and the cost is higher than that of reduced powder and atomized powder.

The above is the preparation method of the metal powder, you can collect it.
