Niobium carbide Specification

This chemical is called Niobium carbide, and its IUPAC name is methylidyneniobium. With the molecular formula of CNb, its CAS registry number is 12069-94-2. Additionally, this chemical is green cubic crystals with metallic luster. It was found in some gypsum-bonded dental investments. Besides, its product categories are Inorganics; Carbides; Ceramics; Metal and Ceramic Science. It's used as a carbide hard alloy additives or purple gem. Keep it in the cool and dry place.

Other characteristics of the Niobium carbide can be summarised as followings: (1)H-Bond Donor: 0; (2)H-Bond Acceptor: 0; (3)Rotatable Bond Count: 0; (4)Exact Mass: 105.914203; (5)MonoIsotopic Mass: 105.914203; (6)Topological Polar Surface Area: 0; (7)Heavy Atom Count: 2; (8)Formal Charge: 0; (9)Complexity: 10; (10)Isotope Atom Count: 0; (11)Covalently-Bonded Unit Count: 1.

Direct method for preparation: Having the Niobium metal powder and carbon black in proportion well-mixed,  heating them in a vacuum or hydrogen to the 1600 ~ 1700 °C, you will directly obtain niobium carbide. The reaction is as follows: 2Nb+C=Nb2C; Nb2C+C=2NbC.

You can still convert the following datas into molecular structure:
1.InChI: InChI=1/C.Nb
2.Smiles: C.[Nb]
