Description of Super Adsorption Activated Porous Carbon Powder
Solid carbon comes in different forms known as allotropes depending on the type of chemical bond. The two most common are diamond and graphite less common ones include buckminsterfullerene. In diamond the bonds are sp3 and the atoms form tetrahedra with each bound to four nearest neighbors.
In graphite, they are sp2 orbital hybrids and the atoms form in planes with each bound to three nearest neighbors 120 degrees apart.
The individual layers are called graphene. In each layer, the carbon atoms are arranged in a honeycomb lattice with a separation of 0.142 nm, and the distance between planes is 0.335 nm. Atoms in the plane are bonded covalently, with only three of the four potential bonding sites satisfied. The fourth electron is free to migrate in the plane, making graphite electrically conductive. Bonding between layers is via weak van der Waals bonds, which allows layers of graphite to be easily separated, or to slide past each other. Electrical conductivity perpendicular to the layers is consequently about 1000 times lower.
The two known forms of graphite, alpha (hexagonal) and beta (rhombohedral) have very similar physical properties, except that the graphene layers stack slightly differently. The alpha graphite may be either flat or buckled. The alpha form can be converted to the beta form through mechanical treatment and the beta form reverts to the alpha form when it is heated above 1300 °C.

Aluminum Diboride Powder RELATED INFORMATION
Aluminum boride is an ionic compound, with a hexagonal crystal structure. Aluminum boride at an absolute temperature slightly 40K (equivalent to -233 ℃) will be transformed into a superconductor. And its actual operating temperature is 20 ~ 30K. To reach this temperature, we can use liquid neon, liquid hydrogen, or closed-cycle refrigerator to finish cooling. Compared to the current industry using liquid helium to cool the niobium alloy (4K), these methods are simpler and more economical. Once it is doped with carbon or other impurities, magnesium diboride in a magnetic field, or there is a current passing, the ability to maintain the superconducting is as much as niobium alloys, or even better.

Iron Boride Powder Description
Iron Boride Powder is often used to improve abrasion resistance, corrosion resistance, wear resistance, and oxidation resistance. It is used in oil and gas refinery, chemical extraction, automotive agricultural, stamping, textile extrusion, and injection molding industries. Iron-based coatings recently gained attention for their mechanical, frictional, and corrosion-resistant properties. As compared to the ceramic or cermet type of materials people have used before, iron-based materials are relatively inexpensive, less strategic, and can be produced economically by various thermal methods with ease of fabrication and machining.

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 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
