摘　　要：铅水晶具有良好的理化性能,但PbO的加入产生了环保和健康问题。以TiO_2替代PbO,制得新型无铅水晶玻璃。通过改变TiO_2在组分中的质量分数,探究TiO_2对水晶玻璃体系的性能影响。结果表明在TiO_2质量分数最高为12%的样品折射率到达1.572,并能显著改善水晶玻璃的热稳定性能。Lead crystal glass exhibits excellent physical and chemical properties, but it is harmful to health and environment. A new lead-free crystal glass was prepared by adding TiO2 instead of PbO. The effect of TiO2 on the properties of crystal glass was investigated through changing the concentrations of TiO2. The results showed that the refractive index reached up to 1.572 when the glass contained 12% of TiO2, and the thermal shock resistance of the crystal glass was also improved obviously.
