Growth Mechanism, XRD, Raman and FTIR Spectroscopic Studies of Potassium Pentaborate (KB5) Crystal Zin Min Tun Win Kyaw Single crystal of potassium pentaborate (KB5) has been grown by solution growth technique. Structural investigation of the crystal was examined by powder XRD method. FTIR and laser Raman measurements were carried out to study the vibrational characterizations of those crystals. The B-O vibrations of ring B-O symmetric stretching, ring B-O asymmetric stretching and the B-O terminal asymmetric stretching have been assigned in the recorded frequency band of 700 cm-1 to 1500 cm-1 region. Furthermore, ring OBO symmetric bending, OH stretching and terminal asymmetric bending vibrations were also observed and studied in this research. In addition, thermal analysis has been investigated by TG-DTA method to study the high temperature phases of the crystal. 2008 http://hdl.handle.net/20.500.12678/0000002673 https://meral.edu.mm/records/2673
