Tungsten carbide powder is one of the most widely used high performance abrasives on the market today. Its properties of hardness and density make it a perfect choice for various applications. However, it is also important to be aware of its hazards and dangers.

The most important advantage of tungsten carbide is its hardness. This makes it suitable for use as abrasives and a material for producing wear parts. In addition, it is also a good conductor of electricity.

It is also a relatively low-density material, making it a suitable option for mass reduction. While it is flammable, it is not a significant hazard in the presence of safety measures.

One of the most common uses for tungsten carbide is for cutting tools. However, it is also used in industrial machinery such as jet engine components. Another common application is for kiln furnace structural materials.

Moreover, tungsten carbide is also a good neutron reflector. Its hardness and compressive strength are similar to that of diamond. Nonetheless, it does not have strong anti-oxidation properties. To minimize the risk of oxidation, a protective coating is applied on the non-working surface.

The main manufacturing processes for tungsten carbide include the casting process. Casting provides a dual-phase structure to the tungsten carbide, which gives it exceptional hardness and wear resistance.

Other methods for manufacturing tungsten carbide powders include chemical vapor transport, extrusion, and hot pressing and sintering. Nanorods can be produced from a tungsten carbide powder through extrusion or chemical vapor transport. They are formed by coating a metal catalyst on the tungsten carbide, and they have a diameter of 2-40 nm.
