Study On Niobium Carbide Properties And NbC Application

Nickelium carbide, a cubic green crystal with metallicluster, belongs to sodium chloride’s cubic crystal type. Niobium carbide, an iron carbide of the chemical NbC.

Niobium Carbide Characteristics

Niobium carbide has a melting temperature of 3500. The elastic modulus of Niobium carbonide is 338000N/mm2, with a thermal expansion coefficient 6.6510/K and a Thermal Conductivity of 14.4 w / (m. K) as well as a resistivity 35/ cm.

Cold and hot sulfuric, cold and warm hydrochloric and nitric- acid acids are insoluble. However, it is easily soluble and mixed with hot hydrofluoric or nitric aqueous solutions. It can be stored at 1000 11100 and becomes quickly oxidized to niobium petrooxide above 1100. You can mix it with zirconium and titanium carbide to form a solid solution.

NBC Applications:

1.NbC applications in composite materials

(1)

Composite ceramics

Multiphase ceramic materials made from manufactured materials include the raw material for multiphase clay materials. These materials are frequently used to make wear-resistant and cutting parts.

(2) Hard alloy

The ability to form a dispersed third phase, with the exceptions of WC and Co and other carbohydrates can increase the thermal toughness and resistance against thermal shock. You can use niobium carbonide to make hard alloy cutting tools.

(3) Surfacing electron

So the welding layer is more resistant to wear, as the hard niobium crate hard phase penetrates into the structure. The electrode surfacing wear resistance is 1.5 1.8 times stronger than that of the quenched 45-steel (HRC50), while 2.4 3.6 times higher for the Fe-CrR-C-B type, wear-resistant alloy.

(4) Aerospace components

It is also used as a preparation material for components of numerous aerospace equipments. This includes turbine rotors.

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

A layer of Niobium Carbide is placed on top of the base metal workpiece. This significantly improves its surface hardness which can reach up to HV2800. In addition, it increases the working temperature of the workpiece and reduces tissue density. Thus, it extends its service life.

(3) Buttons of niobium Caride

Niobium carbide is used to coat high temperature parts of the spacecraft, increasing their durability. An ultra-fine coating of cobalt-containing, niobium carbonide makes up the inner layer of electron emission tubes. This material is widely used in electronics.

3. NbC applications in the fabrication of metal-niobium

The country uses indirect reduction to make metallic niobium. It is commonly used as an intermediary to convert niobium niobium into metallic niobium. Also, niobium carbide can reduce niobium pentoxide directly to create pure metal.
