| Abstract: | X-ray study, density measurement and estimation of aoousto-optic properties of the compounds in PbO-Nb2O5 system were carried out. Existence of the six PbO-NbaOs compounds reported by Roth was confirmed by X-ray analysis. Cell parameters and powder diffraction data were accurately measured for the compounds P3N and P5N2. It was found that in the mixture of PbO and Nb2O5 with a composition of P5N2 heated at 900~1150℃ there exists P3N as an intormediate phase. In this system the compounds P3N, P5N2, P2N and P3N2 with high PbO contents all possess large values of acousto-optio figures of merit and thus are promising new aoousto-optic materials. |
