Phase equilibria in the system Li2O-MgO-B2O3

The subsolidus region of the Li2O-MgO-B2O3 system has been studied by X-ray powder diffraction and differential thermal analysis. Isothermal sections at 500--550 and 650--700DGC have been designed. The following complex borates have been found to form: at 500--550DGC, Li2MgB2O5 and LiMgBO3 are forme...

Zusammenfassung:	The subsolidus region of the Li2O-MgO-B2O3 system has been studied by X-ray powder diffraction and differential thermal analysis. Isothermal sections at 500--550 and 650--700DGC have been designed. The following complex borates have been found to form: at 500--550DGC, Li2MgB2O5 and LiMgBO3 are formed; at 650--700DGC, a new phase Li4MgB2O5 is formed along with LiMgBO3; and at 5500--600DG, Li2MgB2O5 is formed.
