研磨用碳化硼F80 Boron carbide Abrasive grain产品简介
碳化硼F80 Boron carbide Abrasive grain是以硼酸和碳素材料为原料,经过高温冶炼而成的高硬度材料。碳化硼分子式为B4C,外观为灰黑色颗粒或粉末。也有人称它为人造黑钻石,是一种硬度很高的硼化物。碳化硼不易与酸、碱发生反应,化学性能稳定,广泛用于硬质材料的研磨、磨削、表面处理等。
碳化硼硬度比人工合成金刚石略低,比碳化硅高,结构易碎性低,具有大的热能中子俘获截面。碳化硼抗化学作用能力强,在受热情况下,不受氟化氢和硝酸的侵蚀。可溶于融化的碱中,不溶于水和酸。密度较低(2.5g/cm3),是一种硬度高且轻质的材料。
Boron carbide F80 B4C Abrasive grain is a high hardness material made from boric acid and carbon materials through high-temperature smelting. The molecular formula of boron carbide is B4C, and its appearance is gray black particles or powder. Some people also call it artificial black diamond, which is a high hardness boride. Boron carbide is not easily reactive with acids and bases, and has stable chemical properties. It is widely used in grinding, grinding, surface treatment, and other hard materials.
Boron carbide has slightly lower hardness than artificially synthesized diamond and higher structural fragility than silicon carbide, and has a large thermal neutron capture cross-section. Boron carbide has strong resistance to chemical reactions and is not corroded by hydrogen fluoride and nitric acid when heated. Soluble in molten alkali, insoluble in water and acid. Low density (2.5g/cm3), it is a material with high hardness and lightweight.
