Nickelium carbide, a cubic green crystal with metallicluster, belongs to this sodium chloride type cubic system. Niobium carbide, an iron carbide of the chemical NbC.
Niobium Carbide Characteristics
The melting point for niobium carbide is 3500. Niobium carbonide has an elastic module of 338000 N/mm2, a thermal expand coefficient of 6.6510 / K, a Thermal Conductivity of 14 W/(m. K) and a resistance value of 35/c.
Cold and hot sulfuric acid, cold and high heat hydrochloric acid, and Niobium pentoxide insolutable. But, they are soluble and stable in hot hydrogen fluoric acid. It can be stored at 1000 11100 and then oxidizes quickly to niobium petrooxide over 1100. You can mix it with zirconium and titanium carbide to form a solid solution.
Fields for NbC App:
1.NbC applications in composite materials
Multiphase ceramic materials made from manufactured materials include the raw materials used to make multiphase material. These materials are frequently used in cutting tools, wear-resistant components, electrodes, etc. because they have high hardness, great chemical stability, excellent conductivity and high melting points.
HTML2_ Hard alloy
The ability to form a dispersed third phase, with Co and WC together with other carbides can increase thermal hardness and resistance against thermal shock. You can use niobium carbonide to make hard alloy cutting tools with outstanding cutting performance.
(2) Surfacing electrode
So the welding layer is more durable and wear resistant, as the hard, niobium carbide-hard phase of the electrode surfacing layers enters the structure. This electrode surface has a wear resistivity of 1.21.8x higher than quenched steel (HRC50), and is 2.53.6 times as strong as the FeCr-CrB type wear resistant alloy.
(4) Aerospace components
It is also used to make parts of various aerospace equipments.
2. NbC applications in coating material
(1) A mold steel coating
Niobium carbonide is a high-hardness metal carbide with high heat and abrasion resistant. This can make the surface of the mold more resistant to wear.
(2) Treatment of metal pieces
The layer of Niobium Carbide is placed on top of the aluminum workpiece. It greatly enhances its hardness and works to increase the overall working temperature and tissue density.
(3) Other Niobium Caride Coatings
Niobium carbide is used to coat high temperature parts of the spacecraft, which increases their useful life. An ultra-fine coating of cobalt-containing, niobium carbonide makes up the inner layer of an electron emission tube. This material is widely used in electronics.
3. NbC applications in the fabrication of metal-niobium
The country relies heavily on indirect reduction for the manufacture of metallic nickel. It is used as an reducing agent to convert the produced niobium to metallic niobium. After that, it is refined and refined to achieve a higher quality metallic niobium. In addition, niobium carbide can reduce niobium pentoxide directly to make pure metal.
