Neutron Powder Diffraction

Nihon Kessho Gakkaishi, 2004
Neutron powder diffraction is a powerful technique to clarify the relationship between the crystal structures and the properties of functional materials. Since neutron atomic scattering factors do not depend on atomic numbers monotonically, neutron diffraction gives more reliable structural information than X-ray to detect light elements among heavy ...

Characterization of a Recyclate‐Based MgO‐Steel Composite As‐Sintered Inert Anode Candidate After Exposure to Cryolite Electrolysis

Advanced Engineering Materials, EarlyView.
Carbon‐free inert anodes are essential for decarbonizing aluminum electrolysis. This study investigates a recyclate‐based MgO‐316L steel composite anode tested under galvanostatic Hall–Héroult conditions in cryolite at 1000°C. Microstructural analysis reveals selective MgO fluorination, spinel and oxide layer formation, electrolyte infiltration, and ...

Powder Optimization Strategies for Binder Jetting Printing of BaTiO3 and Ba0,6Sr0,4TiO3 Ceramics

Advanced Engineering Materials, EarlyView.
Powder optimization is investigated to enable binder jetting of BaTiO3 and Ba0.6Sr0.4TiO3 ferroelectric ceramics. The antagonistic relationship between flowability and binder compatibility is addressed through binder impregnation of granulated powders and fumed silica addition to fine powders.

A high-resolution neutron diffraction and electron diffraction study of the structure and phase transitions in AgTaO3

APL Materials
The high temperature phase transition behavior of the quantum paraelectric material, AgTaO3, has previously been debated in the literature. To elucidate the phase transitions of AgTaO3, we used neutron powder diffraction and established the phase ...

Magnetic ordering in Gd5Ir2Bi and Gd5Ir2Sb

AIP Advances, 2016
155Gd Mössbauer spectroscopy and neutron powder diffraction have been used to study magnetic ordering in Gd5Ir2Bi and Gd5Ir2Sb. Despite the hyperfine fields (Bhf) at the two Gd sites differing by more than a factor of two for both compounds, the moments ...
