Abstract
Structural analysis of bariumborate (BaOB_2O_3) melts prepared from a-phase or β-phase has been described with special reference to the relationships between melt structure and crystal structure before melting. The difference of crystal structure before melting was not well recognized in the RDF data. It was, however, ascertained that the different behavior, indicating the characteristic features deduced from crystal structutes before melting, is detected in the profiles of 3rd and 4th peaks of the reduced interference function.
