Study of the Structure of Zn and Na Borophosphate Glasses Using X-ray and Neutron Scattering Techniques
Autor: Uwe Hoppe, Parker T. Freudenberger, Richard K. Brow, Jozef Bednarčik, Alex C. Hannon
Publikováno v: Solids, Vol 5, Iss 3, Pp 355-374 (2024)
The atomic structures of Zn and Na borophosphate glasses were studied using X-ray and neutron scattering techniques. Peaks assigned to the B−O, P−O, and O−O distances confirm that only BO4 units co-exist with the PO4 tetrahedra. The Zn−O and

Dissolution rates of borophosphate glasses in deionized water and in simulated body fluid
Autor: Parker T. Freudenberger, Rebekah L. Blatt, Richard K. Brow
Publikováno v: Journal of Non-Crystalline Solids: X, Vol 18, Iss , Pp 100181- (2023)
Particles of borophosphate glasses with the nominal molar compositions 16Na2O-(24-y)CaO-ySrO-xB2O3-(60-x)P2O5 (mol%), where 0 ≤ x ≤ 60 and y = 0, 12, and 24, were reacted in deionized water and in simulated body fluid (SBF) at 37 °C. For the dis

The structure and properties of xZnO–(67–x)SnO–33P2O5 glasses: (IV) Mechanical properties
Autor: Richard K. Brow, Hiromichi Takebe, Takaya Okamoto, Akira Saitoh, Parker T. Freudenberger
Publikováno v: Journal of Non-Crystalline Solids. 513:44-48
The Vickers hardness, Young's modulus, and shear modulus of xZnO–(67–x)SnO–33P2O5 glasses increase with increasing values of x, in agreement with predictions that consider the quantitative structural information regarding coordination numbers o
