Advanced ceramics, also known as engineering or technical ceramic
2、s, refer to materials which exhibit superior mechanical properties, corrosion/oxidation resistance, and thermal, electrical, optical or magnetic properties. Advanced ceramics are generally broken down into the following segments: structural ceramics, electrical and electronic ceramics, ceramics coat
3、ings, chemical processing and environmental ceramics. Structural ceramics include applications such as industrial wear parts, bioceramics, cutting tools, and engine components. Electronic ceramics, which have the largest share of the advanced ceramic market includes capacitors, insulators, substrate
4、s, integrated circuits packages, piezoelectrics, magnets and superconductors. Ceramic coatings find application in engine components, cutting tools, and industrial wear parts. The applications under chemical processing and environmental ceramics include filters, membranes, catalysts, and catalyst su
5、pports. B卷 【第1页 共2页】2. In the same way, resonance theory says that benzene cant be described satisfactorily by a single line-bind structure but is instead a resonance hybrid .of two forms. Benzene doesnt oscillate back and forth between two forms; its true structure is somewhere between the two. Eac
6、h carbon-carbon connection is an average of 1.5 bonds, midway between a single bond and a double bond3. Recall that an inductive effect is due to an electronegativity difference between the ring and the attached substituent, while a resonance effect is due to orbital overlap between a p orbital on t
7、he ring and a p orbital on the substituent. 三、Fill in the blank with the given expressions. (16 points)A) activated carbon, silica gel, and alumina B) adsorption and with regligible loss of other materials C) isotherms D) usually weak and reversible E) bind strongly F) effects on adsorption are prof
8、ound G) molecules or particles to a solid surface H) little variation in temperature Adsorption Adsorption is the binding of 1 , which must be distinguished from absorption. The binding to the surface is 2 . But compounds with color and those that have taste or odor tend to 3 . Compounds that contai
9、n chromogenic groups (atomic arrangements that vibrate at frequencies in the visible spectrum)very often are strongly adsorbed on activated carbon. Decolorization can be wonderfully efficient by 4 .The most common industrial adsorbents are 5 , because they present enormous surface with high adsorpti
