摘要
基于两种分散剂聚甲基丙烯酸钠(PMAA-Na)和聚甲基丙烯酸铵(PMAA-NH4)制得纳米级氧化铝陶瓷坯体和基片。针对其力学性能、电性能做了全面的测试研究。主要包括两种分散剂对坯体强度、坯体及基片显微结构、基片密度、基片的介电常数、介质损耗、绝缘强度等影响。通过测试,发现两种分散剂下制的基片,均满足高性能氧化铝陶瓷基片的性能要求。
two kinds of dispersing agents PMAA-NH4 and PMAA-Na nano alumina ceramic body and substrate based on. According to the mechanical properties, electrical performance test and comprehensive study. Mainly includes two kinds of dispersants on the green body strength, the body and the substrate, the substrate microstructure density, substrate dielectric constant, dielectric loss, dielectric strength influence. Through the test, found that the substrate two dispersants under the system, can satisfy the requirements of properties of high performance alumina ceramic substrate.
