【Abstract】 The chemical stability of lanthanum glass is influnenced by the glass systems. Lanthanumglass;ystems of Si-B-La-Ba and B-La-Zn-Ba are clianged into the systems of B-La-Y with additives ofTa₂O₅, TiO₂, WO₃, ZrO₂, etc, added for adjusting the glass properties and improving the chemicalstahility of the giass.更多还原
