Boron Carbide (B4C), popularly known as black diamond, is the third hardest material after diamond and Cubic Boron Nitride. Because of its remarkable mechanical qualities, Boron Carbide is widely used in industries that require strong wear resistance and fracture toughness. Boron Carbide is also commonly used in nuclear reactors as control rods, shielding materials, and neutron detectors because of its ability to absorb neutrons without producing long-lived radionuclides.
Wintrustek produces Boron Carbide ceramics in three purity grades and using two sintering methods:
96% (Pressureless Sintering)
98% (Hot Press Sintering)
99.5% Nuclear grade (Hot Press Sintering)
