Abstract

fetched live from OpenAlex

Ceramics of (1-x)BaTiO 3 −xBiScO 3 solid solution with compositions x = 0, 0.01, 0.03, 0.05 and 0.10 were synthesized in pure perovskite phase by a solid state reaction. The dielectric and ferroelectric properties were investigated. The temperature dependence of the dielectric permittivity shows that the ferroelectric T C increases with the increasing amount of BiScO 3 substitution, which was confirmed by differential scanning calorimetry (DSC). While three dielectric anomalies associated with the three structural phase transitions were clearly observed in pure BaTiO 3 , the two anomalies at lower temperatures were impaired by the substitutions of BiScO 3 for BaTiO 3 . The DSC measurements reveal that the two peaks associated with the lower temperature phase transitions disappear after the BiScO 3 substitution. These results demonstrate the significant effects of BiScO 3 on the structural phase transitions and dielectric and ferroelectric properties of the (1-x)BaTiO 3 −xBiScO 3 solid solution.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
