微米级碳化硼粉Boron carbide powder 28um 20um 14um

蓝宝石晶体窗口片研磨用碳化硼50um 60um 40um是以硼酸和碳素材料为原料，在电弧炉中经过高温冶炼、破碎筛分、水力分级生产出的高硬度研磨微粉。碳化硼分子式为B4C，外观为灰黑色颗粒或粉末。碳化硼又称“黑钻石”，是一种硬度很高的硼化物，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。碳化硼莫氏硬度为9.36，显微硬度为4950 KGF/mm2，粒度分布集中，适用于半导体行业蓝宝石晶体窗口片、衬底片的单面和双面研磨减薄。

Grinding grade boron carbide is a high hardness grinding micro powder produced by high-temperature smelting, crushing and screening, and hydraulic classification in an electric arc furnace using boric acid and carbon materials as raw materials. The molecular formula of boron carbide is B4C, and its appearance is gray black particles or powder. Boron carbide, also known as "black diamond", is a type of boride with high hardness. Boron carbide has a slightly lower hardness than artificially synthesized diamond and a higher hardness than silicon carbide, with a lower structural fragility. The Mohs hardness of boron carbide is 9.36, the microhardness is 4950 KGF/mm2, and the particle size distribution is concentrated. It is suitable for single-sided and double-sided grinding and thinning of sapphire crystal window sheets and substrates in the semiconductor industry.
