This study investigates the preparation of TiO–SiO–CaCO composite opacifier (Ti–Si–Ca) and its application in sanitary ceramic glazes. This approach involved hydrophobic agglomeration through surface-induced hydrophobic modification of TiO, SiO and CaCO particles, along with the interactions between the hydrophobic carbon chains of modifiers. The Ti–Si–Ca formed a uniform coating with well-dispersed

A hydrothermal method was employed to synthesise zinc aluminate oxides doped with manganese, with the aim of enhancing the photocatalytic reduction of hexavalent chromium to trivalent chromium. The optical, textural, microscopic, and structural features of the materials were assessed by a range of analytical techniques. These results revealed that incorporation of Mn dopant into the ZnAlO (ZAO) reduced

Microstructure, thermal/mechanical properties and corrosion behaviors of ternary and quaternary equimolar rare-earth monosilicates Ceram. Int. (IF 5.2) Pub Date : 2024-04-17 Chaowen Zhu, Wei Liao, Xiaochun Han, Zhen Teng, Peng Jia, Xiaosong Zhou, Yongqiang Tan
The properties of rare-earth (RE) monosilicates can be regulated by solid solution engineering based on the mixture rule. The combination and number of RE principals are critical factors for better performances. In the present study, four single-phase equimolar multicomponent RE-monosilicate solid solutions including (DyErYb)SiO, (HoErYb)SiO, (YErTmLu)SiO and (DyErTmYb)SiO were synthesized by solid-state

Preparation of Eu2+ and Dy3+ co-doped Sr2MgSi2O7 translucent long afterglow glass-ceramics by recrystallization-melting and their luminescence properties Ceram. Int. (IF 5.2) Pub Date : 2024-04-16 Tuo Song, Xueyi Pan, Yajuan Zhao, Wei Xia
In this work, a novel recrystallization-melting method was used to prepare Eu and Dy co-doped SrMgSiO translucency long afterglow glass-ceramics with complete crystal development. The synthesis mechanism is discussed by analyzing the detection results of X-ray diffraction, scanning electron microscopy, phosphorescence spectra, and afterglow attenuation curves. The effect of different firing temperatures

Microstructure and mechanical property regulation of plasma-sprayed high-entropy (La0.2Nd0.2Sm0.2Eu0.2Gd0.2)2Zr2O7 thick coatings Ceram. Int. (IF 5.2) Pub Date : 2024-04-16 Caizhi Peng, Wenzhi Huang, Xin Zhou, Panhao Deng, Ling Zhu, Huijun Jiang
The effect of critical plasma spraying parameters (CPSPs) on phase composition, microstructure and mechanical property of (LaNdSmEuGd)ZrO thick coatings was investigated. After coating deposition, the phase structure of (LaNdSmEuGd)ZrO was transformed from pyrochlore to fluorite in the coating. When the CPSP value increased from 0.83kW/Lpm to 1.17kW/Lpm, the porosity of as-deposited coating was decreased

To predict oxidative damage of interfaces and fibers under high temperature aerobic environment and mechanical strength of composites before and after oxidation, oxygen permeation mass transfer modeling and onion-like micromechanical modeling of multilayered interface were proposed. The oxygen mass transfer theory and oxidation damage theory of PyC interface were used to establish the two models. The

SiO2 and Fe cation synergistically modify the LaMnO3 NTC thermistors with high stability Ceram. Int. (IF 5.2) Pub Date : 2024-04-16 Xiaotian Jin, Zhilong Fu, Donglin He, Yi Liu, Xia Huang, Pengjun Zhao, Qing Zhao, Aimin Chang
SiO insulator and FeO dopant was simultaneously used to modify the crystalline phase, morphology and electric properties of LaMnO ceramics. Results show that there are several merits after modification. On the one hand, the addition of SiO is demonstrated to have multifunction to the LaMnFeO (0 ≤ x ≤ 0.5) (LMFO) ceramics. After adding SiO, the surface of LMFO ceramics tend to be flat, the degree of
