Abstract

Abstract: To explore the influence of the organic carbon source on the refining of TiB₂ powder,TiB₂ powder was prepared by borothermal/carbothermal reduction using TiO₂,B₄C and sucrose as raw materials,insulating at 1 150,1 250,1 350 and 1 450 ℃ for 30 min,respectively.The reaction mechanism of the TiO₂-B₄C-sucrose system,as well as the refining mechanism of TiB₂ grains was initially explored.The results show that Ti₂O₃ and TiC are two important intermediate products during the borothermal/carbothermal reduction process,which are both generated by the direct reaction of TiO₂ and C.Subsequently,TiB₂ may be generated with Ti₂O₃ or TiC as the titanium source reacting with B₂O₃ and C.In addition,the highly activated nanocarbon from sucrose pyrolysis has a pore structure,which can improve the reaction efficiency and successfully enable the preparation of submicron TiB₂ powder with an average particle size of 0.35 μm under the condition of insulating at 1 450 ℃ for 30 min.

Key words: TiB₂, sucrose, borothermal/carbothermal reduction, pore structure

摘要： 为探讨有机碳源对TiB₂粉体细化的影响,以TiO₂、B₄C和蔗糖为原料,分别在1 150、1 250、1 350、1 450 ℃ 保温30 min,通过硼热/碳热还原法制备了TiB₂粉体,并初步探讨了TiO₂-B₄C-蔗糖体系的反应机制以及TiB₂晶粒的细化机制。结果表明:在硼热/碳热还原过程中,Ti₂O₃和TiC是两种重要的中间产物,且均由TiO₂和C直接反应生成,随后TiB₂则可能以Ti₂O₃或TiC为钛源分别与B₂O₃和C反应生成。此外,由于蔗糖裂解出的高活性纳米碳具有孔隙结构,可提高反应效率,使得该体系在1 450 ℃保温30 min的条件下成功制备出平均粒径为0.35 μm的亚微米级TiB₂粉体。
