AbstractThe effect of water vapor on the structure of anhydrous potassium pentaborate was studied at high temperature by self-designed reactor in the present paper. The vibration spectra of anhydrous potassium pentaborate crystal at high temperature were analyzed by X-ray diffraction spectrum(XRD), infrared spectrum(IR) and Raman spectrum. The ratio of B2O3 to K2O in potassium pentaborate was, diminished by reacting with water vapor. XRD analysis shows that K5B19O31 exists in potassium pentaborate crystal at 750 degrees C, while IR and Raman analysis show that some triangular structure units (B-(3)-O) are changed to tetrahedral structure units(B-(4)-O) in the crystal. The content of tetrahedral structure unit(B-(4)-O) increases and the network configuration between boron and oxygen is farther broken.
