Boron carbide is a hard and dense ceramic material made by combining carbon molecules with boron. It is used in nuclear power, manufacturing, and as armor due to its durability and resistance. However, it is expensive and has potential drawbacks such as thermal shock failure and susceptibility to oxidation.
Boron carbide is one of the hardest and densest materials on earth. Manufacturers produce this special ceramic product by combining carbon molecules with a naturally occurring element called boron. These materials can be combined in an electric arc furnace or using an acid-based chemical reaction, both of which result in a material with four molecules of boron and a single molecule of carbon. The supreme level of hardness and density of this material make it suitable for a wide variety of highly specialized applications that cannot be achieved with any other material.
One of the most common applications for boron carbide is in the nuclear power industry. Boron carbide is one of the few materials on earth that can safely contain nuclear control rods and prevent radiation leaks. This material also serves as an effective radiation shield outside of the nuclear industry, such as in a hospital or research setting where large amounts of radioactive energy may be used.
Boron carbide is also used extensively in the manufacturing industry to make materials that require the highest level of durability. For example, this material is used to make armor for vehicles, as well as highly effective armor for soldiers and law enforcement personnel. It is also used on high quality locks and security devices due to its ability to resist almost any type of tampering or forcing. Manufacturers use boron carbide to make nozzles and other accessories for sandblasting equipment and to coat metal tools and other mechanical parts subject to high wear.
Many of boron carbide’s natural properties make it suitable for the toughest applications. This black or dark gray powder offers diamond-like hardness and density, and also offers extreme wear resistance. It has a high melting point and is chemically inert, which prevents unwanted reactions with surrounding materials or compounds. It is also light in weight and can be heat pressed into molds to form many shapes.
Despite its many advantages, boron carbide is also associated with a number of potential drawbacks in some applications. Temperature changes can lead to a phenomenon known as thermal shock failure and this material is also more susceptible to oxidation than other similar materials. Boron carbide products are limited to only what can be created using heat press manufacturing, as other manufacturing techniques are not suitable for this material. Finally, boron carbide is extremely expensive, typically costing five to ten times as much as steel.
