In situ high-temperature X-ray diffraction, conventional X-ray diffraction, thermal analysis, Fourier transform infrared spectroscopy, and scanning electron microscopy were used to determine the effects of different heating temperatures on the structure, morphology, and composition of the samples. The results showed that chambersite phase transformation from the orthorhombic system to the cubic system occurred at 408–410 °C. At 900 °C chambersite was partially decomposed to form new crystals such as manganese metaborate [Mn(BO2)2] and iron oxoborate (Fe3BO6); the manganese metaborate further decomposed into manganese oxide and boric acid at 1000 °C. Chambersite generated a large number of columnar crystals at 900 °C. The recrystallization of chambersite was facilitated by a furnace-controlled cooling process at 900–1050 °C, allowing sufficient energy and time. The present study reflects the thermal reaction of chambersite, which could be applied in microwave absorbing and neutron shielding ceramic materials.

Prédiction machine sur la base complète
Imitation des enseignantsNi prévalence calibrée, ni vérité terrain. Validation humaine à venir. Le volet Gemma est une étiquette directe du modèle pour chaque travail de la base, lue sur la notice réduite au titre. Le volet Codex est un classifieur appris des 10 348 étiquettes directes de Codex et calibré sur les taux pondérés de l'échantillon; les champs sans appui suffisant ne portent aucun appel Codex. Le mode candidate est l'union des deux volets; le consensus est leur intersection. Ces sorties portent le statut machine_predicted_unvalidated et ne sont pas des étiquettes humaines.

Scores machine (provisoires)
Les deux têtes enseignantes du modèle étudiant, lues sur ce travail. Un score ordonne la base pour la relecture; il n'affirme jamais une catégorie, et le statut de validation accompagne chaque rangée tel quel.
Scores de référence d'un modèle non mature (critères de maturité non atteints, 7 itérations). Un score ordonne; il n'affirme jamais une catégorie.
