Raman scattering study of crystalline and melting states of BaO center dot 2B(2)O(3)

Solntsev VP, Davydov AV, Malinovsky VK, Surovtsev NV

Melting and crystallization scenarios of barium tetraborate BaB4O7 (Ba0.2B2O3) are studied in situ by Raman spectroscopy. It is shown that the scenario depends on the temperature-time history of melt. Crystallization conditions of the beta modification of barium tetraborate (beta-BaB4O7) from a stoichiometric glass structure BaO center dot 2B(2)O(3) were investigated. (C) 2010 Elsevier B.V.
