AI Technical Summary

Technical Problem

The existing radiation-resistant glass formula contains lead, which makes it difficult to meet the radiation resistance, refractive index and expansion coefficient requirements of the optical fiber panel. The decreased transmittance leads to unclear images and cannot meet environmental protection and technical requirements at the same time. Existing technology cannot effectively solve this problem.

Method used

By adding CeO2 and TiO2 as variable valence oxides, combined with BaO and La2O3, a lead-free glass composition is formed. The ionic valence changes of CeO2 and TiO2 are used to absorb radiation energy. BaO improves the refractive index and radiation resistance. At the same time, the chemical stability and transmittance of the glass are improved by adding BaO, TiO2 and La2O3.

Benefits of technology

It does not immediately discolor under high-energy rays, has good visible light transmittance and radiation resistance, meets environmental protection requirements, and is suitable for fiber optic panels, especially in the fields of industrial detection and medical testing.
