Introduction to Chromium-Carbide Cr3C2 Pulp
This inorganic compound has the molecular structure Cr3C2 and a molecular mass of 180.01. It is a gray powder containing a rhombic structure, A =2.821 and B =5.52, respectively, C =11.46. The melting point is 1890, while the boiling point is 3800. The micro-Vickers hardness, load 50g, is 2700kg/rnrn2, thermal extension coefficient is 10.3×10-6/K.
It exhibits good wear resistance, corrosion resistance and oxidation resistance at high temperatures (10001100). It belongs to the cermet family. It has a high temperature performance and is widely used in thermal spraying materials for metal surface protection processes as well as as additives to the cemented carbide industry.
Chromium Carbide Cr3C2 Pulp has Physical Properties
Many excellent properties include high chemical stability, high-temperature toughness, thermal hardness and resistance to acid and alkali corrosion, wear resistance, and high melting points. Chromium carbide can be used as an inhibitor to control grain growth in cemented carbide.
Furthermore, chromium carbide is a strong abrasion resistant of explosive bonding materials additives. It has been used extensively in the metallurgical and electronic industries, as well as aerospace, high-temperature resist coatings, and other areas.
Chromium carbide is a common surface coating in the field of cutting tools. Chromium carbide, an important precipitated phase of Fe-Crr-c alloy, makes the material extremely wear resistant.

Methods of Preparation for Chromium Carbide Cr3C2 powder
Carbonization of metal chromium powder:
After grinding carbon black at 13.5%64% (mass) ratio, 325-mesh chromium powder can be made. It is then dried mixed with a ballmill and used as a raw material. Use 1% – 3% stearic as a forming oil. Do not pressure mold more than 1 T/cm2. Pressurized molding powder is used to mold graphite disks or crucibles.

Chromium Carbide Cr3C2 Pulp
1. Can be used as carbide additions (such as tungsten-based carbide grains refiner), in mining, mechanical processing and other aspects.
2. These can be used to add to welding materials. The welding rod is made of chromium caride and can be used for surfacing welding on some equipment such as jaw plates, ball mills, coal mills, etc. This can increase the equipment’s service life by several times.
3. Useful for thermal spraying metal surfaces.
