Niobium Carbide Properties

About Niobium Carbide NbC Powder:

Niobium carbide NbC is an extremely hard refractory ceramic material used commercially for cutting tools. It is usually processed by sintering and is commonly used as a grain growth inhibitor additive in cemented carbides. Niobium carbide is a brown-gray metal powder with a purple luster. It is highly corrosion-resistant. Niobium carbide is one of the hardest technical compounds known. Niobium carbide, which has Young's modulus of about 452 GPa, is a common product in micro-alloy steels because of its extremely low solubility in austenite, which is the lowest of all refractory metal carbides. This means that the micron-sized NbC precipitates are almost insoluble in the steel at all processing temperatures, and their location at grain boundaries helps prevent excessive grain growth in these steels. This is also a huge benefit for the base of micro-alloyed steel, as it is uniform and has a very fine grain size, ensuring toughness and strength.

Product Performance of Niobium Carbide NbC Powder CAS 12069-94-2:

Niobium carbide NbC powder is a dark gray-brown powder with a cubic crystal structure and a metallic luster. It is stable at 1000 to 1100 °C and rapidly oxidizes to niobium pentoxide above 1100 °C.

Niobium carbide NbC powder has good chemical stability and high-temperature performance. It is a high melting point and high hardness material.

Niobium carbide NbC powder is insoluble in cold and hot hydrochloric acid, sulfuric acid, and nitric acid, and it is soluble in hot hydrofluoric acid and nitric acid mixed solution.

Niobium carbide NbC powder is easily melted in compounds such as titanium carbide, zirconium carbide, and tungsten carbide, and together form a homogeneous solid solution mixture, a commonly used cemented carbide additive.

How is Niobium Carbide NbC Powder Produced?

Niobium pentoxide reduction method:

Niobium carbide can be prepared by heating niobium oxide in a vacuum at 1800℃ and adding coke.

In industry, niobium carbide is usually prepared with niobium pentoxide and carbon black as raw materials. Will first proportion of niobium pentoxide and carbon black by carbide material, fully mixing, the load in the graphite crucible, with high-frequency electric furnace under the condition of hydrogen gas or vacuum heating to 1600 ~ 1800 ℃, for the first time, carbide and then adding carbon black, make its mix, under hydrogen gas or vacuum heating to 1800 ~ 1900 ℃, second carbide, This is niobium carbide.


Applications of Niobium Carbide NbC Powder:

As a partial substitute for tantalum carbide, NbC powder is widely used in high-temperature refractory materials and carbide additives

1. As a carbide additive, it is ternary and quaternary carbide solid solution components, such as WC-NBC-C ternary system, etc. It can also be used as a purple artificial gem.

2. Used for the production of wear-resistant film and semiconductor film. It can also be used as raw material to produce molybdenum carbide. It can be used to manufacture special alloys and engineering ceramics without chromium.


 Storage Condition of Niobium Carbide NbC Powder:

The damp reunion will affect NbC powder dispersion performance and using effects. Therefore, niobium carbide NbC powder should be sealed in vacuum packing and stored in a cool and dry room. The niobium carbide can not be exposed to air. In addition, the NbC powder should be avoided under stress.


Packing & Shipping of Niobium Carbide NbC Powder:

We have many different kinds of packing, which depend on the niobium carbide NbC powder quantity.

Niobium carbide NbC powder packing: vacuum packing, 1kg/bag, 25kg/barrel, or as requested.

Niobium carbide NbC powder shipping: could be shipped out by sea, by air, or by express as soon as possible once payment is received.
