| 摘 要： | 为了提高臭氧发生器的臭氧产量,要求臭氧发生器用的陶瓷基板材料具有较高的介电性能和热导率.本文研究了掺杂成分CaO、Y2O3、YF3、(Y,Ca)F3对臭氧发生器用AlN陶瓷基板材料的相对密度、热导率、介电常数、介质损耗等性能的影响.采用XRD分析其物相和SEM观察其显微结构,结果表明,掺杂成分对改善陶瓷基板材料性能的作用大小依次排列为(Y,Ca)F3>YF3>Y2O3>CaO,最适合的掺杂配方是(Y,Ca)F33.0wt%,YF32.0wt%,Y2O31.0wt%,CaO1.0wt%.

| Abstract: | To raise ozone output of ozonator,it demands that ceramic plate materials for ozonator have good dielectric properties and quite high thermal conductivity.The effects of adding CaO?Y 2O 3?YF 3 and (Y,Ca)F 3 on relative density,thermal conductivity,dielectric constnt,dielectric loss et al of AlN ceramic plate material are studied.Phase composition is analyzed by XRD.Micro-stucture is observed by SEM.The results show that the effects of dopant on improving the properties of ceramic plate materials are arranged.i.e.(Y,Ca)F 3>YF 3>Y 2O 3>CaO.The most suitable dopant is (Y,Ca) F 33.0wt%,YF 32.0wt%,Y 2O 31.0wt%,CaO1.0wt%. |
