A: The theoretical density is 2 g/cm³.
A: The material is a grey-white uniform powder without foreign objects. When cold-pressed, it appears grey, and when heat-treated to porcelain, it appears black.
A: The granularity of the powder ranges from 2 to 50 μm.
A: The ionic conductivity is approximately 12 mS/cm at 27°C. The test results using carbon indium lithium electrodes may vary slightly.
A: The electronic conductivity is less than 1×10⁻⁸ S/cm at 27°C in cold-pressed powder form and less than 1×10⁻⁷ S/cm at 27°C in ceramic form.
A: The conductivity activation energy is 0.275 eV (26.6 kJ/mol) within the temperature range of 25 to 85 °C.
