Phase formation in the CaO–Al2O3–ZnO system as an analogue to CaO–Al2O3–MgO in spinel containing refractories

Journal of the American Ceramic Society, Volume 108, Issue 5, May 2025.
Abstract Recently, gahnite (ZnAl2O4) is gaining attraction as a potential refractory ceramic because of the similarity of its structure and properties with those of magnesium aluminate (MgAl2O4) spinel refractories. Formation of MgO and hibonite solid solution (CaMgxAl12−xO19−0.5x; 0 ≤ x ≤ 0.18), CAM‐I (Ca2Mg2−3xAl28+2xO46 (0 ≤ x ≤ 0.3), and CAM‐II ...

Utilization of Novel (KNbO3)1−x(Ba2FeNbO6)x (x = 0.1, 0.2, 0.3) Solid Solutions for Efficient Photo‐Assisted Fenton Degradation of Methylene Blue Dye

Advanced Energy and Sustainability Research, Volume 6, Issue 1, January 2025.
This study develops (KNbO3)1−x(Ba2FeNbO6)x (x = 0.1, 0.2, 0.3) solid solutions for effective photo‐assisted Fenton degradation of methylene blue dye. Ba corrects NbO6 distortions in KNbO3, improving charge transport, while Fe ions extend light absorption to 660 nm and enable Fenton activity, leading to rapid dye breakdown via a synergistic photo‐Fenton
