  2. Boron trioxide - Wikipedia

    en.wikipedia.org/wiki/Boron_trioxide

    Boron trioxide or diboron trioxide is the oxide of boron with the formula B 2 O 3.It is a colorless transparent solid, almost always glassy (amorphous), which can be crystallized only with great difficulty.

    Materials Data creates JADE software used to collect, analyze, and simulate XRD data and solve issues in an array of materials science projects. In 2020, the ICDD and the Cambridge Crystallographic Data Centre, which curates and maintains the Cambridge Structural Database, announced a data partnership.

  4. Ellingham diagram - Wikipedia

    en.wikipedia.org/wiki/Ellingham_diagram

    The original paper by Ellingham explicitly to the reduction of both oxygen and sulfur by metallurgical processes, [1] and anticipated the use of such diagrams for other compounds, including chlorides, carbides, and sulfates. The concept is generally useful for studying the comparative stability of compounds across a range of partial pressures ...

  5. X-ray fluorescence - Wikipedia

    en.wikipedia.org/wiki/X-ray_fluorescence

    X-ray diffraction (XRD) is still the most used method for structural analysis of chemical compounds. Yet, with increasing detail on the relation of K β {\displaystyle K_{\beta }} -line spectra and the surrounding chemical environment of the ionized metal atom, measurements of the so-called valence-to-core (V2C) energy region become ...

    Three-dimensional X-ray diffraction (3DXRD) is a microscopy technique using hard X-rays (with energy in the 30-100 keV range) to investigate the internal structure of polycrystalline materials in three dimensions.

  9. Wide-angle X-ray scattering - Wikipedia

    en.wikipedia.org/wiki/Wide-angle_X-ray_scattering

    X-ray diffraction is a non destructive method of characterization of solid materials. When X-rays are directed at solids they scatter in predictable patterns based on the internal structure of the solid. A crystalline solid consists of regularly spaced atoms (electrons) that can be described by imaginary planes.
