Zinc Sulphide Powder Description
Zinc sulfide Powder is an inorganic compound with the chemical formula of ZnS. This is the main form of zinc found in nature, where it mainly occurs as the mineral sphalerite. Although this mineral is usually black because of various impurities, the pure material is white, and it is widely used as a pigment. In its dense synthetic form, zinc sulfide can be transparent, and it is used as a window for visible optics and infrared optics.
Both sphalerite and wurtzite are intrinsic, wide-bandgap semiconductors. These are prototypical semiconductors, and they adopt structures related to many of the other semiconductors, such as gallium arsenide. The cubic form of ZnS has a bandgap of about electron volts at 300 kelvins, but the hexagonal form has a bandgap of about electron volts.
ZnS can be doped as either an n-type semiconductor or a p-type semiconductor. Fine ZnS powder is an efficient photocatalyst, which produces hydrogen gas from water upon illumination. Sulfur vacancies can be introduced in ZnS during its synthesis; this gradually turns the white-yellowish ZnS into a brown powder, and boosts the photocatalytic activity through enhanced light absorption Zinc sulfidic, with the addition of few ppm of suitable activator, exhibits strong phosphorescence, and is currently used in many applications, from cathode ray tubes through X-ray screens to glow in the dark products. When silver is used as an activator, the resulting color is bright blue, with a maximum at 450 nanometres.

Product Name: Ferro Titanium Carbide Powder
Product Ferro Titanium Carbide Powder Colour Gray Powder Purity ≥ 99.9% Particle size 1-10 µM (customizable) Ingredient/MF FeTiC Product Code NCZ-C-102/20 CAS Number 12604-56-7 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
MF: NbB Chemical Name Niobium Boride Powder
EINECS: 235-723-2 Purity: 99.9% Molecular weight: 103.72 Product Number: NCZ-SC-112/20 Cas Number: 12619-90-8 Density 7.39g/ml Niobium Boride Powder Description
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
A high-energy ball mill for 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 into a single NbB phase without leaving behind NbB2 and Nb3B4 phases.

Tungsten Carbide Powder
Product Name: Tungsten Carbide Powder
Product Tungsten Carbide Powder Colour Grey Purity ≥ 99.9% Particle size 1-10 µM (customizable) Ingredient/MF WC Product Code NCZ-C-109/20 CAS Number 12070-12-1 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 Powder
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.
