materials are generally composed of at least two elements:one(or more)metallic element and one non-metallic.Metal oxides(Al2O3,ZrO2,FeO,etc.)are common examples of ceramics,but other compounds such as carbides and nitrides are also included.掌握词汇：ceramic srmk 陶瓷，compose kmpoz组成，element 元素，metallic mtlk金属的，non-metallic 非金属的，metal oxide金属氧化物，compound kmpand成分，carbide kbad碳化物，nitride natrad氮化物Classic

manufacturing and use problems;high value-added products owing to their sophisticated processing technology;not presently profitable in terms of return of investment(ROI),but which offergreat promise for the future;and positioned at the beginning of the development cycle and not yet widely usedwith respect to their potential.The term“advanced ceramics”refers to ceramic materials that are:by

ceramics.These,in contrast to structural ceramics,utilize microstructural effects localized within the volume,at grain boundaries or at the surfaces of conducting or nonconducting ceramics.Such

所有的所有的Exercise1Exercise2What is the differences between functional ceramics and structural ceramics?Based on their applications,advanced ceramics are usually classified into two major classes:structural ceramics and functional ceramics.While the applications of structural ceramics demands the optimization of mechanical strength,hardness,toughness,and wear resistance,the performance of functional ceramics is controlled by electric,magnetic,dielectric,optical,and other properties.Structural Advanced CeramicsFunctional Advanced CeramicsClassic CeramicsAdvanced
