The Grain Structure of Nd Doped Y₂NiMnO₆ Ceramics Sintered at High Temperature

Abstract

The granular structure of ceramic material influences the electrical properties. Ceramics of YMNO (Y2NiMnO6) doped with Nd were produced by compression and sintering. Grain size was determined from SEM image analysis. Generally, As the Nd dopant concentration was increased, the grain size increased with sintering time. However, at the highest dopant levels of 30% and 20% Nd, a large range in grain size was observed with regions of defective growth. In contrast, a more uniform grain growth was seen for the 10% Nd doped ceramic at all sintering times.
