The effect of Sr and Mg substitutions on the mechanical properties and solubility of the fluorapatite ceramics for biomedical applications
Bibliographic record
Abstract
Abstract The ionic substitutions play important role in the modifications of the biological apatites. Recently, the attention has been focused on the co-doping effects of additives on the functional properties of apatite based biomaterials. Under a research work for which the results are presented here, the dense samples of fluorapatites: Ca 10 (PO 4 ) 6 F 2 and Ca 8 MgSr(PO 4 ) 6 F 2 were produced after sintering at a temperature of 1250 °C for 6 hours in air. The XRD, IR and Raman spectrometry results show a high crystallinity of the fluorapatite and strontium-magnesium-doped fluorapatites. The results demonstrate the stability of structural and mechanical properties of fluorapatites after immersion tests in saline and buffer solutions. The durability of mechanical properties and biocompatibility of Ca 10 (PO 4 ) 6 F 2 and Ca 8 MgSr(PO 4 ) 6 F 2 fluorapatites make these materials highly attractive for biomedical application.

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.
