2、 （48 points）1. Advanced ceramics, also known as engineering or technical ceramics, 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

3、segments: structural ceramics, electrical and electronic ceramics, ceramics coatings, 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

4、 share of the advanced ceramic market includes capacitors, insulators, substrates, 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 a

5、nd environmental ceramics include filters, membranes, catalysts, and catalyst supports. 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 a

6、nd forth between two forms; its true structure is somewhere between the two. Each 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 substitu

7、ent, while a resonance effect is due to orbital overlap between a p orbital on the 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

8、) usually weak and reversible E) bind strongly F) effects on adsorption are profound 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 compound

9、s with color and those that have taste or odor tend to 3 . Compounds that contain 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 indust

10、rial adsorbents are 5 , because they present enormous surface with high adsorptive capacity.Temperature 6 , and measurements are usually at a constant temperature. Graphs of the data are called 7 . Most steps using adsorbents have 8 .B卷 【第2页 共 2 页】1 2 3 4 5 6 7 8 黄冈师范学院20092010学年度第一学期期末试卷参考答案及评分标准考试
