Tóm tắt

The infrared absorption spectra of fused B2O3 and of a series of soda borate glasses are presented. These spectra were obtained using vacuum‐pressed briquettes of the powdered glass and powdered KBr. The spectrum of fused B2O3 shows quite definitely that this glass does not consist of a completely continuous triangularly coordinative network. It is shown that hydrogen bonds play an important part in the atomic arrangement of the glasses of zero or low soda content. The B2O3 glass apparently consists of complexes of an approximate unit (B9O14)‐ held together by hydrogen bonds. One in nine borons is tetrahedrally coordinated. The glasses of low soda content are similar. The spectra for soda concentrations greater than 15% did not permit the determination of the atomic arrangement with exactitude, but it is shown to be quite different from that found in glasses with 10% Na2O or less.
