Read： 590 Time：17months ago Source：Transform the World with Simplicity

Chromium is an important metal element, which is widely used in alloy manufacturing and electroplating. Chromium powder is a form of chromium, is a kind of metal powder, because of its excellent corrosion resistance, oxidation resistance, widely used in all walks of life. The manufacturing process of

chromium powder
the manufacturing process of
chromium powder mainly has two kinds: atmosphere reduction method and physical method. The

atmosphere reduction method is a method in which a reducing agent and a metal oxide are reacted at a high temperature to reduce a metal into a metal powder. In the manufacturing process of chromium powder, the commonly used reducing agents are hydrogen, gas and liquefied petroleum gas. Physical method refers to the direct crushing of metal rods, wires, etc. by high-energy mechanical action to obtain powder. Application fields of

chromium powder

chromium powder is widely used in batteries, alloys, metallurgy, chemical industry, machinery manufacturing, materials science and other fields.

1. Battery field

chromate battery is a widely used battery, and chromium powder is one of the important raw materials for making chromate batteries. Chromium powder in the chromate battery not only as a conductive agent and catalyst, but also can increase the surface area of the electrode and improve the performance of the battery.

2.
in the field of alloy
Chromium powder is widely used in the field of alloy manufacturing. Chromium powder can enhance the hardness, corrosion resistance and heat resistance of metal. Common alloys include ferrochrome, molybdenum-chromium, and titanium alloys.

3. Metallurgical field

Chromium powder is widely used in the field of metallurgy casting, welding and thermal spraying. The application of chromium powder in iron-based alloy and stainless steel can increase the corrosion resistance, wear resistance and high temperature resistance of the material.

4. chemical field

chromium powder can be used as catalyst and reducing agent, widely used in chemical industry. For example, in organic chemistry, chromium powder is used to reduce compounds such as ketones and aldehydes, and in catalysts for the manufacture of acrylic acid and acrylates, etc.

5.
in the field of mechanical manufacturing
chromium powder can be used as a metal coating material, in the field of mechanical manufacturing to increase the hardness and wear resistance of the metal surface.
