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,Advanced,What is the differences between classic ceramic and advanced ceramic?,High-temperature stability(up to 2500 C and beyond), high hardness, high corrosion resistance, low thermal expansion, high wear-resistant and a variety of electrical properties ranging from insulators to semiconductors to highly conductive materials,掌握词汇： High-temperature stability stblti高温稳定性， hardness 硬度， corrosion kron resistance rzstns耐腐蚀性， thermal ml expansion kspnn热膨胀， wear-resistant 耐磨性 ， insulator nslet绝缘体， semiconductor ,smkndkt 半导体， conductive kndktv导电的,掌握词汇： mineral mnrl矿物，refractory rfrktri耐火材料， cement smnt水泥， porcelain pslen瓷器， structural clay kle 结构粘土， purity pjrti纯度， mechanical mknkl机械的、力学的， electrical lktrkl电的， magnetic mgntk 磁的， optical ptkl光学的.,Classification, highly specialized by exploiting unique electric, magnetic, optical, mechanical, biological, and environmental properties; performing well under extreme conditions such as high temperature, high pressure, high stress, high radiation, and high corrosive exposure; predominantly inorganic nonmetallic; relatively expensive, with properties and failure mechanisms not yet fully understood; capable of solving current 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 offer great promise for the future; and positioned at the beginning of the development cycle and not yet widely used with respect to their potential.,The term “ advanced ceramics ” refers to ceramic materials that are:,by VAMAS ( Versailles Project on Advanced Materials and Standards ; Early and Rook, 2004 ), the ASTM Committee C - 28 on Advanced Ceramics, and the USACA ( United States Advanced Ceramics Association),掌握词汇： biological ,baldkl 生物的， environmental 环境的， extreme conditions 极端条件， radiation ,reden辐射， inorganic nrgnk nonmetallic 无机非金属， failure felj mechanisms mknzmz 失效机理， manufacturing 制备， sophisticated sfstketd processing technology 精细加工技术， development cycle 研发周期， potential ptnl潜力、潜能；电势,掌握词汇： toughness tfns韧性，flexibility ,flksblti柔韧性，impact mpkt resistance 抗冲击性,掌握词汇：cutting tool 切削刀具， grinding rand disk 砂轮，wire-drawingdr die da 拉丝模具， crucible krsbl坩埚,掌握词汇：cordierite krd,rat堇青石(硅酸盐矿物)，titanate tat,net perovskite prvzkait 钙钛矿型钛酸盐，calcium klsm phosphate fsfet 磷酸钙, ferritesfrat 铁氧体, Substratesbstret基片，Capacitor kpst电容，Sensorsns 传感器，Laser materials 激光材料，Magnetmgnt磁铁，Hip joints 髋关节，Bone replacement 骨替代，Mechanical resistance 机械阻力，Surface finish 表面抛光，Biocompatibility ,baokm,ptblti生物相容性,Advanced Structural Ceramics: These are used for applications where a component of an engineering system is subjected to high mechanical, tribological, thermal, or chemical loads. Typical structural ceramics are alumina, partially and fully stabilized zirconia, cordierite, mullite, spinel, silicon nitride and SiAlONs, silicon carbide, boron nitride, titanium nitride, and titanium boride.,掌握词汇： Component kmponnt组分 Tribological ,trabldkl摩擦的 Alumina lumn氧化铝 Stabilized zirconia zkon稳定氧化锆 Mullite mlat莫来石(铝硅酸盐矿物) Spinel spnl尖晶石(镁铝氧化物矿物) Silicon slkn nitride 氮化硅 SiAlON 塞隆陶瓷 Silicon carbide 碳化硅 Boron born nitride 氮化硼 Titanium tatenm nitride 氮化钛 Titanium boride 硼化钛,Advanced Functional Ceramics: Polycrystalline or monocrystalline inorganic materials possessing electric, magnetic, elastic, biologic, superconductive, or other chemical functions are called functional 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 effects encompass semiconducting, varistor, piezoelectric, thermoelectric, ferroelectric and superconducting properties, etc.,掌握词汇：Polycrystalline ,plkrstlan 多晶的 ， monocrystalline ,mnkrstlan单晶的，elastic 有弹性的， superconductive 超导电的，volume vljum 体积， grain ren boundarybandri 晶界 ，surface 表面， varistor verst压敏电阻，piezoelectric pa,izolktrk压电的， thermoelectric ,mlektrk热电的，ferroelectric ,frolktrk铁电的,The Current World Market Situation,Advanced Structural Ceramics,Advanced Electronic Ceramics,Advanced Ceramic Coatings,Chemical Processing and Environm
