Boron carbide ceramic sheet is a high performance material made of boron carbide (B₄C), thickness 3-15mm, length 50mm/100mm.Boron carbide is an extremely hard material, with a Vickers hardness of 3000-4000 HV and a density of approximately 2.52 g/cm³, which is lower than other hard ceramics, which helps to keep it lighter in some applications. Boron carbide ceramics are extremely heat-resistant, capable of sustained operation at temperatures up to 2000°C without morphological change or melting, and still maintain their structural stability in high-temperature fields such as aerospace. Boron Carbide Ceramics Due to its hardness and surface smoothness, boron carbide ceramic sheet exhibits a low coefficient of friction during friction and has good wear resistance in mechanical applications. Boron carbide ceramics are non-conductive materials with good electrical insulation, which makes boron carbide very suitable for applications requiring electrical isolation and insulation, such as use as an insulating material in electronic devices.
