After fully dispersing in an ethanol medium and drying, perform dry pressing under the conditions of -100MPa for 30s with a weight of 0.3g. After sintering at approximately 1100℃, polish the sample with sandpaper to 3000 grit, then spray gold on it for measurement. (Note: The dry pressing conditions can be optimized; this example is for reference only and shall be determined based on the dispersion state and powder condition. Pressures ranging from 100MPa to 200MPa have been tested.) The equipment used is a German SP300 electrochemical workstation. For measurements at different temperatures, the temperature is increased via an oven and stabilized for 30 minutes before conducting gradient measurements at respective temperatures.
Particle size < 80 nm: Amorphous; > 300 nm: Monoclinic phase.
