Phosphate and Borophosphate Glasses for optical and Biomedical Applications
… connect the network structures of phosphate and borophosphate glasses to the compositional dependence of properties related to biomedical applications. The glasses were characterized by a variety of techniques, including phosphate ion chromatography, Raman spectroscopy, and <sup>11</sup>B and …

Borophosphate der Haupt- und Nebengruppenmetalle: Synthese, Charakterisierung und Strukturchemische Klassifizierung
Es werden neue Erkenntnisse über Borphosphat und Borophosphate der Haupt- und Nebengruppenmetalle vorgestellt. Neben Hydrothermalsynthesen und Feststoffreationen, die üblicherweise zur Synthese von Borophosphaten angewendet werden, haben insbesondere die solvothermalen Experimente mit Alkoholen …

Preparation and characterization of templated borophosphates and metalloborophosphates
The new borophosphates described here were synthesized under mild hydrothermal conditions (170 oC or 220 oC). Powder and single crystal X-ray diffraction were employed to determine and refine the crystal structures. DTA-TG methods were used to analyze the thermal stability. High temperature powder …

New Developments in the Crystal Chemistry of Selected Borophosphates and Phosphates
Borophosphates are intermediate compounds of systems MxOy–B2O3–P2O5–(H2O) (M = main group or transition metal) which contain complex anionic structures built of interconnected trigonal–planar BO3 and / or BO4 and PO4 groups and their partially protonated species. The main objective of the present …

Development and characterization of sintered porous bioactive glass scaffolds for medical application
… the resulting microstructures of borosilicate, borophosphate, and phosphate bioactive glass scaffolds. The study developed glass ceramics using traditional melt-quench methods; silicate composition S53B50 was processed at 1200 °C, while the P40B10 and Sr phosphate glasses were heated to 1100 °C. …

Phosphate-doped borosilicate enamel coating used to protect reinforcing steel from corrosion
… anions, along with some borophosphate bonds. With the addition of P<sub>2</sub>O<sub>5</sub>, the silicate network is repolymerized and tetrahedral borates are converted to trigonal borates, because the phosphate anions scavenge sodium ions from the borosilicate network. …

Development and characterisation of phosphate glasses for athermalisation
… cations while the change in the properties of borophosphate glasses depended on the effect and coordination number of B<sup>3+</sup>. Glasses with negative dn/dT have been achieved from the various compositions of glasses studied. The results showed that there was a minimum thermal expansion …
