The structure analysis of sodium tetragermanate glass has been carried out on the basis of X-ray diffraction using the pair function method. The thermodynamically stable Na4Ge9O20 and metastable wadeite type Na2Ge4O9 crystals, precipitated in the Na2O路4GeO2 glass on reheating, were selected ...

The surface structure of the deposited oxide was sensitive to the annealing temperature after oxidation. The Na 2 O/Pd(100) surfaces gave rise to a (3 × 3) LEED pattern when annealed at 600 K under vacuum. A model based on Na 2 O(100) was proposed for the (3 × 3) overlayers, ...

Sodium Chromate Cr-51 Lewis Structure Loading... sodium chromate cr-51 has 27 valence electrons shared by 7 atoms and 4 bonds.
From the Raman analysis, it is confirmed that phosphate network form metaphosphate structure. Bioactivity of the glass is studied by immersing the prepared glass in simulated body fluid (SBF). All the glasses exhibited bioactivity after soaking in SBF. Addition of B 2 O 3 to the glass by ...
The present paper mainly focused on how B2O3 and Na2O additions influenced the structure of the Ti-bearing fluoride-free mold flux and investigated how the boron-related units were affected by Na2O. Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy, 11B magic angle spinning-nuclear...
In R2O–Al2O3–SiO2 glasses (R2O is an alkali oxide) Al2O3 enters the structure either as AlO4 or AlO6 units, depending on the composition. For (Al2O3/R2O)≤1 only AlO4 are assumed to form in such glasses [1], [2]. This means that Al2O3 has priority to associate itsel...
However, the mechanism of the change in the slag structure caused by the basic component is unclear due to the limited experimental methods. In addition, CaO is not a universal flux because a strong crystallization tendency occurs when the SiO2/Al2O3 ratio of coal ash is low, which results...
