摘要:

先進(jìn)陶瓷材料作為工程材料和功能材料的重要組成部分，在新能源、通信電子、半導(dǎo)體、航空航天等工業(yè)領(lǐng)域具有廣闊的應(yīng)用前景。但是由于陶瓷粉體多為離子鍵或共價鍵化合物，采用傳統(tǒng)燒結(jié)工藝制備致密陶瓷材料所需的燒結(jié)溫度較高，保溫時間較長，不可避免地會導(dǎo)致晶粒粗化及氣孔殘留，進(jìn)而影響陶瓷材料的各項性能。為了降低燒結(jié)溫度、縮短燒結(jié)時間、提高燒結(jié)致密度與材料性能，各國研究人員先后開發(fā)了多種新型燒結(jié)技術(shù)，包括放電等離子燒結(jié)（spark plasma sintering，SPS）、閃燒（flash sintering，F(xiàn)S）、冷燒結(jié)（cold sintering，CS）以及振蕩壓力燒結(jié)（oscillatory pressure sintering，OPS）等。利用上述燒結(jié)技術(shù)，可顯著降低陶瓷材料的燒結(jié)溫度和燒結(jié)時間，提升材料的各項性能，從而使陶瓷材料的應(yīng)用范圍得以擴(kuò)展。從理論及應(yīng)用兩方面綜述了先進(jìn)陶瓷材料燒結(jié)新技術(shù)的研究進(jìn)展，闡述了燒結(jié)新技術(shù)在高性能陶瓷材料制備過程中的技術(shù)優(yōu)勢和應(yīng)用前景，期望為陶瓷燒結(jié)新技術(shù)的研究、開發(fā)及應(yīng)用提供參考。

Abstract:

As an important component of engineering and functional materials, advanced ceramic materials have broad application prospects in new energy, communication electronics, semiconductor, aerospace and other industrial fields. However, because most of the ceramic powders are ionic bond or covalent bond compounds, the traditional sintering process requires high sintering temperature and long holding time to prepare fully dense ceramics, which inevitably leads to grain coarsening and pore residue, thus affecting the properties of ceramic materials. In order to reduce sintering temperature and time, as well as improve the density and properties of ceramic materials， many novel sintering technologies have been developed, including spark plasma sintering (SPS), flash sintering (FS), cold sintering (CS) and oscillatory pressure sintering (OPS). By using the above sintering technology, the sintering temperature and sintering time of ceramic materials can be significantly reduced, and the properties of materials can be improved, so that the application scope of ceramic materials can be expanded. In this paper, the research progress of novel sintering technologies for advanced ceramics is reviewed from both theoretical and practical aspects. The technical advantages and application prospects of novel sintering technologies in the preparation of high�瞤erformance ceramics are described. It is expected that this paper can provide reference for the research, development and application of novel sintering technologies for advanced ceramics.
