Preparation of ZrO_2 and Al_2O_3 composite powder by gel co-precipitation method
Bibliographic record
Abstract
Gel co-precipitation method and heterogeneous azeotropic distillation technics were used in the preparation of ZrO_2 and Al_2O_3 composite powder.The effect of pH values and the ratio of ZrO_2/Al_2O_3 on the properties of the composite powder and the composite ceramics was investigated.The results show that the t-ZrO_2/Al_2O_3 composite powder with well dispersed and less agglomeration was obtained at pH value of 8.6.In the sintering process,the alumina with high elastic modulus develops its pinning effect,blocking the Zr~(4+)(Y~(3+))mass transfer process and the movement of grain boundary.The grain growth of zirconia was inhibited with the increasing content of alumina,which resulted in higher crystallization temperature of zirconia,higher density and higher strength of composite ceramics.

Full frame distilled prediction
Teacher imitationNot 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.
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 teacher head, not a consensus.
