Solidification behaviour of BaB2O4 melts
Experimental evidence has been obtained that both α‐ and β‐phase BaB2O4 material can be grown directly from pure melts. Growth of α‐phase material onto a platinum rod is initiated by α‐phase structural centers present in the melts which are stable at temperatures around or just above the melting poi...

| description | Experimental evidence has been obtained that both α‐ and β‐phase BaB2O4 material can be grown directly from pure melts. Growth of α‐phase material onto a platinum rod is initiated by α‐phase structural centers present in the melts which are stable at temperatures around or just above the melting point. Overheated melts in which solid nuclei are destroyed have modified freezing characteristics and form β‐phase material. β‐phase material can be produced onto a platinum rod at temperatures well above the reported phase transition temperature.
