Developments in the Integrated Modification of Mechanical and Electromagnetic Characteristics of SiC-based Ceramics
摘要
Abstract
Silicon carbide(SiC),as an electromagnetic wave absorbing material with excellent dielectric properties,has important application value in the fields of communication,radar,medical treatment and so on,especially in the field of national defense,which is very important for stealth technology.Although SiC has the advantages of high stability,high strength,corrosion resistance and high temperature resistance,it also has the disadvantages of poor impedance matching and single absorbing mechanism.With the continuous progress of science and technology,higher requirements are put forward for the properties of SiC Based Ceramics. This paper reviews the latest research progress in the modification of electromagnetic and mechanical properties of SiC-based ceramics.Special attention was paid to improving the mechanical properties of SiC-based ceramics by means of precise control of material components,optimization of sintering process,adjustment of additive types and proportions,and temperature control.In this paper,the modification methods of electromagnetic properties of SiC-based ceramics were introduced in detail from the two dimensions of coating and structural ceramics,and the key roles of the strategies of synthesizing nanocomposites,adding multifunctional fillers,nano structure control and nano particle modification in the collaborative optimization of electromagnetic properties and mechanical properties were discussed. These strategies not only significantly enhanced the bending strength and fracture toughness of the materials,but also effectively improved the electromagnetic wave absorption and shielding effectiveness through the optimization of electromagnetic parameters,which provided new possibilities for the application of electromagnetic wave absorbing materials in extreme environments,and provided rich technical routes and application prospects for the development of multifunctional SiC-based ceramic materials. The purpose of this review is to provide a solid theoretical basis and practical guidance for the research and application of SiC-based ceramic in the field of high-performance electromagnetic wave absorbing materials,in order to promote the rapid development and wide application of related material technology,and help to enhance industrial competitiveness,national security and sustainable economic and social development.关键词
