Abstract

fetched live from OpenAlex

Single crystals of the x Pb(Sc 1/2 Nb 1/2 )O 3 – y Pb(Mg 1/3 Nb 2/3 )O 3 – z PbTiO 3 (PSMNT 100 x /100 y /100 z ) ternary system have successfully been grown by a flux method using 71.4 mol% PbO–28.6 mol% B 2 O 3 flux. The crystals were grown in a platinum crucible by mass crystallization achieved by the slow cooling of a 50PbO:20B 2 O 3 :30PSMNT 29/34/37 (mol%) molten solution from 1,200°C to 880°C at 1.2°C/h. The resulting two types of crystals, 2–3 mm in length with perovskite structure and 5–7 mm in length with pyrochlore structure, coexist. Inductive charge plasma (ICP) chemical analysis revealed that the composition of the pulverized powder of perovskite crystal is PSMNT 43/17/40, which is slightly different from the charged composition of PSMNT 29/34/37. One of the single crystals near the morphotropic phase boundary (MPB) showed a dielectric constant peak of 200°C. The grown PSMNT crystals show good thermal stability of the perovskite phase with partical decomposition starting at 1128°C and peritectic melting at 1308°C.

Full frame distilled prediction

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.
