FAQ：

Q1:

What are the physical properties of iron powder? 

Color: The color of iron powder is usually black or dark gray, which is due to the small particle size of iron powder and the weak ability of the surface to reflect light.

Density: Iron powder has a relatively high density of about 7.87g/cm³, which gives it a high volume mass in some applications.

Form: Iron powder is usually in powder form, with a smaller particle size and a higher specific surface area. This makes the iron powder easy to mix and come into contact with other substances, thereby increasing its activity in certain reactions.

Magnetic: Iron powder is magnetic and can be attracted by magnets. This property makes iron powder in the field of magnetic materials, electromagnetic shielding, and other important applications.

Electrical conductivity: The electrical conductivity of iron powder is relatively high, which makes it have a certain application value in the electronics industry.

Q5：

What are the production processes of iron powder? 

Reduction method: This is one of the main methods of iron powder production. Iron powder is obtained by reducing iron from iron-containing raw materials through carbon-reducing agents (such as coke, charcoal, anthracite, etc.) under high-temperature conditions. Iron powder production by reduction method has the advantages of high yield, low cost, and mature technology, so it has been widely used in industry.

Atomization method: The atomization method is atomizing molten iron into fine droplets through high-pressure airflow or centrifugal force and then cooling and solidifying into iron powder. The iron powder produced by the atomization method has fine particle size, high sphericity, and a smooth surface, which is suitable for powder metallurgy, injection molding, and other fields.

Electrolysis: Electrolysis is a method of producing iron powder by electrolysis of an iron-containing solution. During electrolysis, iron ions are reduced from the solution and deposited on the cathode, producing iron powder. 

Carbonyl process: The carbonyl process produces iron powder using the thermal decomposition reaction of carbonyl iron. In the carbonyl process, iron reacts with carbon monoxide at high temperatures to produce carbonyl iron, and then the carbonyl iron undergoes thermal decomposition to produce iron powder. The iron powder produced by the carbonyl method has high purity, fine particle size, and good surface activity, but the production process is complicated, and the cost is high.
