Cobalt Micro Powder Description:
Cobalt is a chemical element with the symbol Co and atomic number. Like nickel, cobalt is found in the Earth’s crust only in chemically combined form, save for small deposits found in alloys of natural meteoric iron.
The free element, produced by reductive smelting, is a hard, lustrous, silver-gray metal. Cobalt-based blue pigments (cobalt blue) have been used since ancient times for jewelry and paints, and to impart a distinctive blue tint to glass, but the color was later thought to be due to the known metal bismuth.
Miners had long used the name for some of the blue-pigment-producing minerals; they were so named because they were poor in known metals, and gave poisonous arsenic-containing fumes when smelted. In 1735, such ores were found to be reducible to a new metal (the first discovered since ancient times), and this was ultimately named for the kobold.
Today, some cobalt is produced specifically from one of a number of metallic-lustered ores, such as cobaltite (CoAsS). The element is, however, more usually produced as a by-product of copper and nickel mining.
The copper belt in the Democratic Republic of the Congo (DRC) and Zambia yields most of the global cobalt production.
World production in 2016 was 116,000 tonnes (according to Natural Resources Canada), and the DRC alone accounted for more than 50%. Cobalt is primarily used in lithium-ion batteries, and in the manufacture of magnetic, wear-resistant and high-strength alloys.
The compounds cobalt silicate and cobalt(II) aluminate (CoAl2O4, cobalt blue) give a distinctive deep blue color to glass, ceramics, inks, paints, and varnishes. Cobalt occurs naturally as only one stable isotope, cobalt-59. Cobalt-60 is a commercially important radioisotope, used as a radioactive tracer and for the production of high-energy gamma rays.

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);
