The green specimens of nano-size Y-TZP are formed by gelcasting method. Using polymer electrolytes NaPAA and NH_4PAA, we have studied the rheological properties of slurry.The optimum pH range is between 8 to 10. The proper amount of dispersant changes with the solid content.The rheological measurements of suspension containing NH_4PAA show lower viscosity.The theoretical green density has been calculated.

研究了水基电泳沉积成型齿科氧化锆氧化铝玻璃渗透陶瓷的成型方法及工艺参数,成功的在石膏代型上成型出了全瓷修复体基底的预成体.并研究了预成体烧结前后及进行玻璃渗透后的结构和抗弯强度.结果表明,水基电泳成型In-Ceram全瓷基底在悬浮液固含量为80%(质量分数,下同),对电极面积约1∶5,对电极距离为2～3 cm,电压为10～30 V时制作出的全瓷预成体结构均一、无裂缝.电泳成型的方式在上述工艺参数下没有改变瓷粉中氧化锆和氧化铝的比例.其中,工作电压为17V时,玻璃渗透后抗弯强度达到峰值(539MPa).水基电泳沉积成型的基底有良好的精度与密合度,工作电压影响预成体的密度和强度,其中当电压为17V时,成型的预成体进行烧结及玻璃渗透后抗弯强度最高,可以满足齿科全瓷修复体的强度要求.

The characteristic of interface depending on the atomic structure exerts an inportant,and sometime controlling,influence on performance of the interacial materials. The present paper reviews the main studies on fine structure of both the materials inter- faces and interfacial reaction products in semiconductor uperlattice,metal multilayer ceram- ics and composite materials by mean of selected area electron doffraction patterns and high resolution electron microscopy. The following features of interfaces are reviewed:the orientation relationships;the char- acteristic of steps,facets and ronghness of interfaces;atomic bonding across the interface;the degree of coherency,the structure of misfit dislocations and elastic relaxations at the inter- faces:the presence of defects at the onterfaces:the structure of the interfacial reaction prod- ucts as well as the reaction kinetics and reaetion mechanism.

Ni-Cr System solar selective thin solid films were prepared by d.c. magnetron reactivesputtering under the atmosphere of O2 and N2. Ni-Cr alloy was chosen as targetmaterial and copper sheets as substrate. Using SEM, Spectrophotometer and Talystepto analyze the relations between the selective characteristic and the structure, theformation and the thickness of the thin films. The aim is to obtain good solar selectivethin films with high absorptance and low emittance, which is applied to flat plate solarheat collectors.
