Sol-gel Synthesis and Characterization of MgCO3 – Al2O3 Composite Solid Electrolytes
Bibliographic record
Abstract
Composite solid electrolytes in the system (1-x)MgCO3 – xAl2O3 with x = 0.1 - 0.9 were synthesized by a sol-gel method and analyzed by X-ray diffraction, differential scanning calorimetry, thermogravimetric analysis, scanning electron microscopy, energy dispersive X-ray, Fourier transform infrared spectroscopy and alternating current impedance spectroscopy for the determination of the phases and crystallinity, thermal stability, surface morphology, elemental composition, chemical bonding and conductivity, respectively. The composites show that, the crystallinity of the composites decreases as the amount of Al2O3 increase which could lead to higher conductivity. The thermal decomposition studies also indicate that the melting and/or decomposition of the composites occur at lower temperature than the pure MgCO3 which normally take place at 350 oC. The composite with the ratio of x = 0.9 give the highest conductivity value in order of 10-4 S.cm-1 as compared to other ratio due to effective transfer of charge carriers in addition to the formation of MgO-Mg2+ species at the interface.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
