微細構造のEDS / EBSD 複合分析

酸化物セラミックスの結晶相同定と分布

酸化亜鉛 (ZnO) セラミックスは高い透明性と導電性などの優れた光電特性と圧電特性を持ち、太陽電池やバリスタなどに利用されています。

組成や構造の最適化によってこれらの特性をさらに向上させるべく、幅広い研究がおこなわれています。

In order to acheive this scientists need to develop a thorough understanding of the microstructure of ZnO ceramics and how microstructural features relate to bulk properties. For example, grain boundaries and orientations within the oxide influence the bulk conductivity and piezoelectric behavior. 

Combined EDS & EBSD with QUANTAX ED-XS

Our QUANTAX ED-XS system enables affordable combined EBSD/EDS characterization of the microstructural and compositional features of ceramic materials.  QUANTAX ED-XS can be used for a statistical analysis of grain boundaries and clean identification of major and minor phases.

QUANTAX ED-XS consists of our unique eFlash XS detector, an XFlash® EDS detector and integrated ESPRIT software for seamless combined EDS and EBSD analysis. The system is a more affordable alternative to conventional EDS/EBSD systems that still delivers high-quality data for phase distribution analysis amongst other forms of microstructure analysis.
