Custom Boron Carbide B4c Disk with Holes for Nuclear Neutron Absorption¹

Preview:

Product Description Product DescriptionBoron 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) Maximum Size600x600mmTypical PropertiesLow densityExceptional hardnessHigh melting pointHigh neutron absorption cross-sectionExcellent chemical inertnessHigh elastic modulusHigh bending strengthTypical ApplicationsSandblasting nozzleShielding for neutron absorptionFocus ring for semiconductorBody armorWear resistant liningProduct Gallery Technical Data Sheet Properties / Material GradesPressureless Sintered Boron CarbideHot Press Sintered Boron CarbideColorBlackBlackPurity(%)96%98% / 99.5%Density (g/cm3)≥2.48≥2.48Flexural Strength (MPa)≥400≥420Vicker's Hardness(Kg/mm2)29003200Modulus Of Elasticity(GPa)400450Fracture Toughness (MPa·m1/2)4.54.5DISCLAIMER: The given data are not binding but are typical values based on sample testing.
