Abstract

Using stainless steel slag and iron tailings as main raw materials, the CaO-MgO-Al2O3-SiO2 (CMAS) glass-ceramics with a solid waste utilization rate exceeding 70 % was prepared, and the effects of Cr2O3 content on the nucleation and crystallization of glass-ceramics were investigated by X-Ray diffraction (XRD). Research indicates that the main crystalline phases of CMAS are all pyroxene, and the content of Cr2O3 increases in a certain range, which promote the crystallization ability of crystals in glass. Besides, the increase of Cr2O3 content within a certain rangepromotes the crystal crystallization in glass. [ABSTRACT FROM AUTHOR]

Abstract

Through the high temperature solution method, three new phosphates, Cs8Pb4(P2O7)4, CsLi7(P2O7)2 and LiCa(PO3)3, were obtained. X-ray diffraction analyses suggest that they crystallize in the space group P1̅ of the triclinic crystal system. However, the three-dimensional (3D) structures of Cs8Pb4(P2O7)4 and CsLi7(P2O7)2 consist of various isolated P2O7 groups, while LiCa(PO3)3 is built up by the 1D (PO3)∞ chain. Detailed structural comparison suggests that the different sizes and coordination environments of Ca2+ and Zn2+ cations influence the whole structures of LiX(PO3)3 (X = Ca and Zn). IR spectroscopy and UV/Vis/NIR diffuse reflectance spectroscopy analyses have been performed to investigate their optical properties. First-principles theoretical studies were also carried out to aid the understanding of electronic structures and linear optical properties. [ABSTRACT FROM AUTHOR]

Abstract

A new barium borate halide, Ba3B10O17Br2, has been obtained. A detailed structural comparison with other barium borate halides suggested that Ba3B10O17Br2 is the first barium borate halide with a B–O layered structure. First-principles theoretical studies were conducted to aid understanding of the electronic structure and optical properties. [ABSTRACT FROM AUTHOR]
