偏磷酸根(PO-3)对氟铝酸盐玻璃透光性能影响

在氟铝酸盐玻璃（AMCSBY）中引入Ba(PO3）2替代BaF2,替代公式为10MgF2-20CaF2-(10-x)BaF2-10SrF2-15YF3-35AlF3-xBa(PO3)2(x=,2,4,6,8)。对玻璃进行了差热分析，结果表明，在氟铝酸盐玻璃中引入偏磷酸盐使玻璃形成能力大大提高；测量了玻璃从紫外到红外的透过光谱和紫外吸收光谱，在玻璃中引入偏磷酸钡使玻璃中红外透过能力下降，红外吸收边带移向短波段，玻璃紫外透过能力得到提高。紫外吸收边带移向紫外波段，由于PO3^-的影响，O－H吸收峰由2830nm移到3145nm。

Influence of Metaphosphate on Optical Transmission of Fluoroaluminate Glass

Ba(PO3)2 was introduced to AMCSBY glass to substitute BaF 2, and some properties of glasses were studied. The substituting formula is 10MgF 2-20CaF 2-(10-x)BaF 2-10SrF 2-15YF 3-35AlF 3-x Ba(PO 3) 2(x=0,2,4,6,8). The results of differential thermal analysis on glasses show that the glass forming ability was improved greatly by introducing metaphosphate to AMCSBY glass. Transmission spectra of glasses were measured from UV to IR, and ultraviolet absorption spectra of some glasses were also measured . With metaphosphate′s being introduced, the middle infrared transmittance of glass reduced, and the IR cut wavelength shifted to short wavelength, but ultraviolet transmittance of glass increase, and the UV cut wavelength shifted to ultraviolet wave band. Influenced by PO - 3, the absorption peak of OH group moved to 3145 nm from 2830 nm.
