B4C boron carbide ceramic plates
are a noteworthy ceramic material with extensive applications in civil, aerospace, and military fields. B4C's most notable feature is its exceptional hardness (Mohs hardness 9.36, microhardness 55GPa-67GPa), second only to diamond and cubic boron nitride. Furthermore, boron carbide has a low density (2.52g/cm³), a high melting point (2450°C), high high-temperature strength, and excellent chemical stability (boron carbide generally does not react with chemical reagents at room temperature, but corrodes slowly in mixtures of hydrofluoric acid, sulfuric acid, and hydrofluoric acid, making it a chemically stable compound). B4C boron carbide ceramic plates exhibit excellent neutron absorption and thermoelectric properties (140s·m⁻¹ at room temperature), making them suitable for use in the manufacture of bulletproof armor, cutting tools, specialized acid- and alkali-resistant materials, thermocouples, and nuclear reactor control and shielding materials. Furthermore, due to its exceptional properties, researchers have also begun researching boron carbide coatings.
Ultra-thin boron carbide ceramic plates can be widely used in the field of neutron detection. They have stable quality and uniform thickness, making them ideal neutron detection materials. In terms of ceramic production, the company has two processes: pressureless sintering and hot pressing sintering. Products produced by different processes have different advantages and are suitable for different scenarios. Pressureless sintered ceramics are cost-effective and suitable for large-scale production. They are suitable for bulletproof materials, seals, nozzles, wear-resistant and heat-resistant materials, and are also suitable for use as general nuclear power materials. Ceramics produced by hot pressing sintering are suitable for small-scale production and can be made into larger sizes. They are suitable for use as nuclear power materials, semiconductor materials, target materials, bulletproof materials, etc.
