Structure of liquid Y3Al5O12 (YAG)
Abstract:
The total structure factor S(Q) and the radial distribution function G(r) of liquid Y3Al5O12 (YAG) were measured at 1770-2230 K by x-ray scattering from samples under containerless conditions in Ar and O2. Nominal coordination numbers are 4 for Al3+ and 6 for Y3+ ions. The G(r) has peaks at r approximately 1.8 A for Al-O, r approximately 2. 25 A for Y-O, and r approximately 3.3-3.6 A assigned to metal ions in adjacent AlO5-4 and YO9-6 polyhedral ions. Relative to the pure oxides, G(r) for molten YAG has smaller half-widths for the Al-O and Y-O peaks, and an increased sensitivity to temperature and the ambient gas composition.

Molecular Solids
Molecular crystalline solids, such as ice, sucrose (table sugar), and iodine, are solids that are composed of neutral molecules as their constituent units. These molecules are held together by weak intermolecular forces such as London dispersion forces, dipole-dipole interactions, or hydrogen bonds, which...
Ionic Crystal Structures
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...

All metallic solids exhibit high thermal and electrical conductivity, metallic luster, and malleability. Many...
