SUMMARY
The discussion focuses on the microstructure of Barium Strontium Titanate (BST) with over 2% borate added to enhance grain size. The SEM image presented reveals significant abnormal grain growth, with grain sizes reaching approximately 100 micrometers. Additionally, the presence of tails emanating from the grains raises questions about their origin, with suggestions that they may be related to preferential growth paths or surface scratches.
