Boron Oxide - an overview | ScienceDirect Topics

The mean coordination number of boron in the B 2 O 3 melt, 3.1, as determined by Biscoe and Waren (1938), does not provide explicit evidence of any change in the boron coordination. In the binary glass-forming systems of alkali metal borates, it is possible to observe change in the trend of a number of physico-chemical properties in the concentration range of approximately 20 mole % of alkali ...
