摘　　要：六方氮化硼(h-BN)陶瓷作为一类性能优异的结构功能一体化陶瓷材料,在航天航空、微电子、冶金等领域具有广阔的应用前景。但h-BN具有特殊的层状结构与层间共价键,在烧结过程中存在难致密的问题。为了促进h-BN陶瓷烧结致密,提升材料的各项性能,研究人员一方面在无压烧结(PLS)、热压烧结(HPS)、放电等离子烧结(SPS)、反应烧结(RS)等传统烧结技术基础上提出新的策略,另一方面开发出了多种新型烧结技术,包括冷烧结(CSP)、振荡压力烧结(OPS)及交联无压焊接等。本文从传统烧结技术及新烧结技术两方面综述了h-BN陶瓷致密技术的新进展,比较各类传统烧结与新烧结技术,结合h-BN陶瓷的典型应用阐述现有烧结技术的发展方向及应用前景,旨在为h-BN陶瓷的烧结致密技术的发展与应用提供参考。Hexagonal boron nitride(h-BN)ceramics,as a type of high-performance structural-functional integrated composite ceramics material,have broad application prospects in aerospace,aviation,microelectronics,metallurgy,and other fields.However,due to the special layered structure and interlayer covalent bonds of h-BN,there are challenges in achieving density during the sintering process.In order to promote the densification of h-BN ceramics sintering and enhance their various properties,researchers have proposed new strategies based on traditional sintering techniques such as pressureless sintering(PLS),hot pressing sintering(HPS),spark plasma sintering(SPS),and reactive sintering(RS).Additionally,they have developed various new sintering technologies,including cold sintering(CSP),oscillating pressure sintering(OPS),and cross-linking pressureless bonding.This review comprehensively summarizes the recent advances in h-BN ceramics densification technology from the perspectives of both traditional and new sintering techniques.By comparing various traditional and new sintering technologies and combining them with typical applications of h-BN ceramics,it elucidates the development directions and application prospects of existing sintering technologies,aiming to provide references for the development and application of sintering densification technology for h-BN ceramics.
