Effect on properties of lead-free crystal

- Aug 08, 2019-

Lead crystal has good physical and chemical properties, but the addition of PbO has caused environmental protection and health problems.A new type of lead-free crystal glass was prepared by TiO2 instead of PbO.By changing the mass fraction of TiO2 in the composition, the influence of TiO2 on the performance of crystal glass system was explored.The results showed that the refractive index of the samples with the highest TiO2 mass fraction of 12% reached 1.572, which could significantly improve the thermal stability of crystal glass.
