Study On Properties Of Transition Metal Oxide Borate Glass

In this paper, the properties of transition metal oxide borate glass were studied. It was found that introducing a small amount of CaO and BaO into borate glass could improve the crystal resistance and chemical stability of the glass. The introduction of V2O5, ZnO, Al2O3, SiO2 and other components is beneficial to widen the glass forming range and improve the anti-crystal performance of glass. The introduction of MgO and ZrO2 can improve the acid resistance of glass. The mixed and co-mixing of Fe2O3, MnO2, V2O5 and other transition metal oxides can increase the total doping amount by more than 30%. At the same time, the introduction of multiple components can effectively prevent glass crystallization and improve the anti-crystallization ability. The developed transition metal oxide borate glass has a resistivity up to 5x1010 Omega.cm, good chemical stability and anti-crystallization ability, and is suitable for the production of large crucible melting, realizing the preparation of 100x100x1mm glass samples.
