Unlike cubic boron nitride, however, boron carbide is easier to produce on a large scale. This study was published in the October issue of the journal Science Advances.īoron carbide, dubbed "black diamond," is a human-made material, which ranks second below another synthetic material called cubic boron nitride for hardness. "Our work finally addresses this unmet need and is a step forward in designing superior body armor that will safeguard against even more powerful firearms during combat." Kelvin Xie, assistant professor in the Department of Materials Science and Engineering. "For the past 12 years, researchers have been looking for ways to reduce the damage caused by the impact of high-speed bullets on armor made with boron carbide," said Dr. By adding a tiny amount of the element silicon to boron carbide, a material commonly used for making body armor, they discovered that bullet-resistant gear could be made substantially more resilient to high-speed impacts. Researchers at Texas A&M University have formulated a new recipe that can prevent weaknesses in modern-day armor.
