Interaction of slip‐ and flame‐spray coated carbon‐bonded alumina filters with steel melts
15-Jan-2018 | Patrick Gehre, Anne Schmidt, Steffen Dudczig, Jana Hubálková, Christos G. Aneziris, Nick Child, Ian Delaney, Gilbert ..., Journal of the American Ceramic Society, 2018
Abstract Ceramic foam filters play an essential role in the quest for cleanliness of cast steel parts as they facilitate turbulence reduction during mold filling as well as removal of nonmetallic inclusions. A coating on these filters is able to increase their strength and filtration ...

Combined experimental and ab initio based determination of the thermal expansion of La0.5Sr0.5Co0.25Fe0.75O3
12-Jan-2018 | X. Yin, A. Beez, N. H. Menzler, R. Spatschek, Journal of the American Ceramic Society, 2018
Abstract The thermal expansion of La0.5Sr0.5Co0.25Fe0.75O3 (LSCF55) is investigated both by first principles phonon calculations combined with the quasi‐harmonic approximation (QHA) and by experimental approaches. Within the framework of the QHA, the volumetric thermal expansion coefficient of ...
Inversion Domain Network Stabilization and Spinel Phase Suppression in ZnO
11-Jan-2018 | Joshua Hoemke, Eita Tochigi, Tetsuya Tohei, Hidehiro Yoshida, Naoya Shibata, Yuichi Ikuhara, Yoshio Sakka, Journal of the American Ceramic Society, 2018
Abstract The development of inversion domain networks consisting of basal‐plane and pyramidal‐plane inversion domain boundary (b‐IDB and p‐IDB) interfaces within grains in Sn‐Al dual‐doped ZnO (Zn0.98Sn0.01Al0.01O) polycrystalline ceramics has been confirmed using transmission electron ...
Boron‐dependent microstructural evolution, thermal stability and crystallization of mechanical alloying derived SiBCN
11-Jan-2018 | Daxin Li, Zhihua Yang, Dechang Jia, Delong Cai, Shengjin Wang, Qingqing Chen, Yu Zhou, Dongli Yu, Yongjun Tian, Journal of the American Ceramic Society, 2018
Abstract Amorphous boron‐rich SiBCN were prepared by high‐energy ball milling of the mixtures of Si, graphite, h‐BN and inorganic boron, which acted as extra boron source. The solid‐state amorphization, thermal stability and crystallization of the boron‐rich SiBCN were studied in detail. It ...
Powder Chemistry Effects on the Sintering of MgO‐doped Specialty Al2O3
11-Jan-2018 | T. Frueh, C. Marker, E. R. Kupp, C. Compson, J. Atria, J. L. Gray, Z.‐K. Liu, G. L. Messing, Journal of the American Ceramic Society, 2018
Abstract In this work we investigate the effects of powder chemistry on the sintering of MgO‐doped specialty alumina. The stages at which MgO influences densification of Al2O3 were identified by comparing dilatometry measurements and the sintering kinetics of MgO‐free and MgO‐doped specialty ...
Chemical composition and temperature dependence of the energy storage properties of Ba1‐xSrxTiO3 ferroelectrics
11-Jan-2018 | Bingcheng Luo, Xiaohui Wang, Enke Tian, Haimo Qu, Qiancheng Zhao, Ziming Cai, Hongxian Wang, Wei Feng, Baiwen Li, Lo ..., Journal of the American Ceramic Society, 2018
Abstract Dielectric materials with high power and energy densities are desirable for potential applications in advanced pulsed capacitors. Computational material designs based on first‐principles calculations provide a “bottom‐up” method to design novel materials. Here, we present a ...
Environmental resistance of Cr2AlC MAX phase under thermal gradient loading using a burner rig
11-Jan-2018 | J. Gonzalez‐Julian, T. Go, D. Mack, R. Vaßen, Journal of the American Ceramic Society, 2018
Abstract Dense Cr2AlC materials were tested under a gradient loading for the first time using a burner rig. The severe thermal cycling conditions consist of 500 short cycles at 1200 °C, with an accumulative time at the maximal temperature of more than 58 29 h. The samples showed no visible ...
Magnetocrystalline anisotropy in the Co/Fe co‐doped aurivillius oxide with different perovskite layer number
09-Jan-2018 | Wen Gu, Xiaoning Li, Shujie Sun, Liuyang Zhu, Zhengping Fu, Yalin Lu, Journal of the American Ceramic Society, 2018
Abstract Perpendicular magnetic anisotropic materials are of great interest for their huge potential to realize high‐density non‐volatile memory and logic chips. Designing such materials with lower cost and better magnetoelectric coupling still remains major challenges. In this work, ...
Polymer derived ceramic adsorbent for pollutant removal from water
09-Jan-2018 | Damla Zeydanli, Suleyman Akman, Cekdar Vakifahmetoglu, Journal of the American Ceramic Society, 2018
Abstract Polymer derived ceramic components (SiOC, sample W) were produced from preceramic polymer mixture and a catalyst. After curing and pyrolysis, some of the samples etched by hydrofluoric acid to obtain carbonaceous SiOC (C‐rich SiOC, sample W‐HF). W and W‐HF were tested as an adsorbent ...
