Tantalum Niobium Carbide Powder Description :
Tantalum Niobium Carbide Powder is a chemical element with the symbol Ta and atomic number. Previously known as tantalum, it is named after Tantalus, a villain from Greek mythology.
Tantalum is a rare, hard, blue-gray, lustrous transition metal that is highly corrosion-resistant. It is part of the refractory metals group, which are widely used as minor components in alloys.
The chemical inertness of tantalum makes it a valuable substance for laboratory equipment, and as a substitute for platinum.
Its main use today is in tantalum capacitors in electronic equipment such as mobile phones, DVD players, video game systems, and computers. Tantalum, always together with the chemically similar niobium, occurs in the mineral groups tantalite, columbite, and coltan (a mix of columbite and tantalite, though not recognized as a separate mineral species.
Tantalum is considered a technology-critical element. Tantalum is dark dense, ductile, very hard, easily fabricated, and highly conductive of heat and electricity. The metal is renowned for its resistance to corrosion by acids; in fact, at temperatures below 150 °C tantalum is almost completely immune to attack by the normally aggressive aqua regia.
It can be dissolved with hydrofluoric acid or acidic solutions containing the fluoride ion and sulfur trioxide, as well as with a solution of potassium hydroxide.
Tantalum’s high melting point of 3017 °C (boiling point 5458 °C) is exceeded among the elements only by tungsten, rhenium, and osmium for metals, and carbon. Tantalum exists in two crystalline phases, alpha, and beta.
The alpha phase is relatively ductile and soft; it has a body-centered cubic structure (space group Im3m, lattice constant a = 0.33058 nm), Knoop hardness 200–400 HN and electrical resistivity 15–60. The beta phase is hard and brittle; its crystal symmetry is tetragonal (space group P42/mnm, a = 1.0194 nm, c = 0.5313 nm), Knoop hardness is 1000–1300 HN and electrical resistivity is relative.
The beta phase is metastable and converts to the alpha phase upon heating to 750–775 °C. Bulk tantalum is almost entirely alpha phase, and the beta phase usually exists as thin films obtained by magnetron sputtering, chemical vapor deposition or electrochemical deposition from a eutectic molten salt solution

| Product Code | NCZ-C-102/20 |

Ferro Titanium Carbide Powder Applications Fields:
Ferro Titanium Carbide Powder is a ferroalloy, an alloy of iron and titanium with between 10–20% iron and 45–75% titanium and sometimes a small amount of carbon. Ferrotitanium can be manufactured by mixing titanium sponge and scrap with iron and melting them together in an induction furnace.
During steelmaking, titanium is usually introduced as ferrotitanium because of its relatively low melting temperature and high density.
Ferrotitanium is usually produced by induction melting of titanium scrap with iron or steel; however, it also is produced directly from titanium mineral concentrates.
Application of Ferro Titanium carbide powder:
In the present study, Fe-based hardfacing coating reinforced by TiC particles was obtained by manual shielded metal arc welding (SMAW) in which H08A bare electrode was coated with fluxes, to which different measures of ferrotitanium, rutile, graphite, calcium carbonate, and calcium fluoride had been added.
The microstructure and wear properties of the hardfacing coating were studied through scanning electron microscopy (SEM), transmission electron microscopy (TEM), an X-ray diffractometer (XRD), and a wear test.
The results indicate that TiC particles are produced by a direct metallurgical reaction between ferrotitanium and graphite during welding.
TiC particles are uniformly dispersed in the matrix of lath martensite and retained austenite with particle sizes in the range of 3–5 μm. Fe-based hardfacing coating reinforced by TiC particles is found to possess better wear resistance and a lower coefficient of friction than that of the AISI 1045 steel substrate.

Niobium Boride Powder
Niobium boride Powders having NbB, NbB2, and Nb3B4 phases in various amounts and single-phase NbB powders were successfully synthesized by using powder metallurgy methods from related metal oxide raw materials in the presence of a strong reducing agent. Nb2O5, B2O3, and Mg powder blends were milled at room temperature by a high-energy ball mill for a different time. Subsequently, an undesired MgO phase was removed from the milled powders by HCl leaching to constitute NbB–NbB2–Nb3B4 as final products, and they were subjected to an annealing process at 1500 °C for 4 h to observe probable boride transformation. Characterization was carried out by XRD, DSC, PSA, SEM/EDX, TEM, and VSM.
The effects of milling time (up to 9 h) on the formation, microstructure, and thermal behavior of the final products were investigated. The reduction reaction took place after milling stoichiometric powder blends for 2 h. Nano-sized NbB–NbB2–Nb3B4 powders in high purity were obtained in the absence of any secondary phase and any impurity via mechanochemistry by milling for 5 h and leaching with 4 mol/L HCl. After annealing, pure and nano-sized NbB–NbB2–Nb3B4 powders transformed to a single NbB phase without leaving behind NbB2 and Nb3B4 phases.

Brief Description of WC Tungsten Carbide Powder
Tungsten carbide powder (chemical formula: WC ) is a chemical compound (specifically, a carbide ) containing equal parts of tungsten and carbon atoms.
In its most basic form, tungsten carbide is a fine Gray powder, but it can be pressed and formed into shapes for use in industrial machinery, cutting tools, abrasives, armor-piercing rounds, other tools and instruments, and jewelry.
Physical Properties of WC Tungsten Carbide Powder
Tungsten carbide has a high melting point at 2,870 °C (5,200 °F), a boiling point of 6,000 °C (10,830 °F) when under a pressure equivalent to 1 standard atmosphere (100 kPa), the thermal conductivity of 110 W·m−1·K−1, and a coefficient of thermal expansion of 5.5 µm·m−1·K−1.
Tungsten carbide is extremely hard, ranking about 9 on Mohs scale, and with a Vickers number of around 2600.
It has Young’s modulus of approximately 530–700 GPa, a bulk modulus of 630–655 GPa, and a shear modulus of 274 GPa.
It has an ultimate tensile strength of 344 MPa, the ultimate compression strength of about 2.7 GPa and a Poisson’s ratio of 0.31.
Chemical Properties of WC Tungsten Carbide Powder
There are two well-characterized compounds of tungsten and carbon, WC and tungsten semi abide, W2C.
Both compounds may be present in coatings and the proportions can depend on the coating method.
At high temperatures, WC decomposes to tungsten and carbon and this can occur during high-temperature thermal spray, e.g., in high-velocity oxygen fuel (HVOF) and high energy plasma (HEP) methods.
Application of WC Tungsten Carbide PowderÂ
1 Used for Producing high capability nano-crystalline or superfine horniness alloy, hard-face abrasion-resistant spraying and petrochemical cracking catalyst;
- Used for chipless forming tools; Cutting tools; Mining tolls; Nano-composites (for enhanced hardness, strength, and wear resistance);
- Used for erosion-resistant coatings; wear-resistance coatings; Corrosion-resistant coatings; Wear-resistant parts
- To produce hard carbide.
