摘要： 本文对PbO-Nb2O5系化合物进行了粉末X线研究,比重测量和声光性质预测.X线分析证实Roth所发表的此系中六种化合物的存在.精确测得了P3N和P5N2的晶胞参数和粉末衍射数据.发现组成为P5N2的PbO、Nb2O5混合物在900℃~1150℃间出现P3N中间相.指出系中PbO含量较高的P3N、P5N2、P2N和P3N2均具有较高的声光优值,有希望作为新的声光材料.

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.
