17-Sep-2015 | Oksana V. Livitska, Nataliia Yu. Strutynska, Igor V. Zatovsky, Nikolay S. Slobodyanik, ChemInform, 2015

Abstract Interactions in the systems MIPO3—MIIO (or Mn2O3)—MICl (MI: Na, K; MII: Mg, Co, Ni, Zn) are investigated at molar ratios P/Mx = 1 or 2, and MICl/(MIPO3 + MIIO) = 30 (porcelain crucibles, 1073 K, 3—5 h).


Nitride bonded silicon nitride as a reusable crucible material for directional solidification of silicon

10-Sep-2015 | V. Schneider, C. Reimann, J. Friedrich, G. Müller, Crystal Research and Technology, 2015

Nitride bonded silicon nitride (NBSN) has the potential of a reusable crucible material for directional solidification of silicon. This is demonstrated in this work by reusing a NBSN crucible six times for the directional solidification of undoped multicrystalline (mc) silicon ingots. The ...

Abstract The Ce3Pd6Sb5‐type rare earth stannides Ln3Au6Sn5 (Ln: La, Ce, Pr, Nd, Sm) are prepared by arc‐melting of stoichiometric mixtures of the elements and subsequent annealing (Ta crucibles in evacuated silica ampoules, 870 K, 3 weeks).


Amorphization and Directional Crystallization of Metals Confined in Carbon Nanotubes Investigated by in Situ Transmission Electron Microscopy

06-Jul-2015 | Dai-Ming Tang; Cui-Lan Ren; Ruitao Lv; Wan-Jing Yu; Peng-Xiang Hou; Ming-Sheng Wang; Xianlong Wei; Zhi Xu; Naoyuki K ..., Nano Letters, 2015

The hollow core of a carbon nanotube (CNT) provides a unique opportunity to explore the physics, chemistry, biology, and metallurgy of different materials confined in such nanospace. Here, we investigate the nonequilibrium metallurgical processes taking place inside CNTs by in situ transmission ...
