1 sty 2023 · Considering P–O bonds in amorphous P 2 O 5, the structure of phosphate glasses was analyzed. Results revealed that the basic structural element of phosphate glasses is the (PO 4) tetrahedron.
A new germanium(II) phosphate, sodium tetragermanium tris(phosphate), Na[Ge 4 (PO 4) 3], has been synthesized by a solid-state reaction. The compound is isotypic with A[Sn 4 (PO 4) 3](A = Na, K, NH 4). It features a [Ge 4 (PO 4) 3] framework made up of GeO 3 pyramids and PO 4 tetrahedra, which are linked by shared corners, yielding a three ...

21 kwi 2021 · The primary objective of this work is to theoretically perceive the influence of germanium co-doping on the heavily P-doped Si crystal by means of CALculation of PHase Diagrams (CALPHAD) approaches and density functional theory (DFT) calculations.
1 mar 2008 · A new series of isostructural open-framework tin(II) phosphates with general formula A[Sn4(PO4)3], where A=Na, K, NH4, has been synthesized by hydrothermal methods.
