Structure, thermal behavior, and chemical durability of lead–calcium–phosphate glasses

60CaO-30P2O5-(10 ̶ x)Nb2O5-xTiO2 (x = 0 ~ 10, mol%) glasses were prepared in order to obtain biomaterials with high chemical durability and therapeutic ions releasability. Dissolution test of these glasses using Tris buffer solution showed the controlled release of niobate ions from Nb2O5-containing glasses and the formation of calcium titanate in some of them. These behavior might induce positive effects for bone regeneration.

Lanthanum calcium phosphate glasses doped with Eu3+ ions in compositions 20La2O3:10CaO:(70-x)P2O5:xEu2O3 (where x = 0.05, 0.10, 0.50 and 1.50 mol%) were prepared by melt-quenching technique. The density and molar volume measurements were carried out at room temperature. The absorption spectra were investigated in the UV-Vis-NIR region from 200 to 2500 nm. The emission spectra of Eu3+-doped glasses centered at 590 nm (5D0→7F1), 612 nm (5D0→7F2), 652 nm (5D0→7F3) and 699 nm (5D0→7F4) have been observed with 393 nm excitation wavelength.

Oxygen Substitution

AbstractBy using both alumina addition and nitrogen/oxygen substitution within PO4 tetrahedra, it is possible to prepare durable phosphate glasses without affecting their specific properties such as low melting temperatures and high thermal expansion coefficients. In particular, “LiKMgAlPON” nitrogen-rich glass compositions have a chemical durability on the same order as soda lime window glass, associated with a glass processing temperature as low as 800°C.
