How many kinds of powder metallurgy powder manufacturing methods?

1. What are the main types of powder metallurgy powder manufacturing methods?

There are two main types of powder manufacturing methods: physical chemistry and mechanical pulverization.
The former includes reduction method, electrolytic method and carbonyl method;

The latter includes grinding and atomization.

2. How do you make metal powder by reduction?

The method is a method to obtain the metal powder by taking the oxygen from the metal oxides by reducing agent.

3. What is the reducing agent?
Reductants are substances that capture oxygen in oxides.
The reducing agent used to make a metal powder is a substance that can remove oxygen from metal oxides.

In the case of metal oxides, it is known as the reducing agent of this metal oxide that the affinity with oxygen is greater than that of the metal and oxygen.
