摘要/Abstract

摘要： 用热压法制备了AlN-BN复合陶瓷材料, 添加CaF₂和Y₂O₃为烧结助剂, 研究了烧结助剂的种类、含量以及不同保温时间对复合材料的物相组成、显微结构和热导率的影响. 添加复合助剂(1～3)wt%Y₂O₃-3wt%CaF2的试样在保温过程中晶界相挥发明显, 净化了复合材料的晶界, 减少了复合材料中AlN晶格缺陷, 获得了纯净的AlN-BN复合陶瓷. 与单独添加CaF₂助剂的试样相比, 添加复合助剂的试样的介电性能没有明显下降, 随复合助剂(1～3)wt%Y₂O₃-3wt%CaF₂中Y₂O₃含量的增加, AlN-BN复合陶瓷的热导率显著提高. 添加复合助剂3wt%Y₂O₃-3wt%CaF₂的试样在1850℃下保温3h获得的热导率为132.7W·m^-1·K^-1.

Abstract: AlN (Aluminum nitride)-BN (Boron nitride) ceramic composites were prepared by hot-pressing in nitrogen atmosphere at 1850℃. Different contents of CaF₂ and Y₂O₃ were added as sintering additives. The effects of sintering additives and soaking time on crystalline phase, microstructure, and thermal conductivity of AlN-BN composite were explored. The experimental results show that the AlN-BN composites with combined sintering additives CaF₂-Y₂O₃ are pure AlN and BN phases, and the grain boundaries evaporate at high sintering temperature. The dielectric properties of the AlN-BN composites with combined sintering additives Y₂O₃-CaF₂ decrease little, comparing with that of the AlN-BN composites with CaF₂ additive. The thermal conductivity is increased with Y₂O₃ contents increasing in the combined sintering additives of Y₂O₃-CaF₂. When AlN-BN ceramic composites with 3wt%Y₂O₃-3wt%CaF₂ is sintered at 1850℃ for 3h, its thermal conductivity of reaches 132.7W·m^-1·K^-1.
