氧化锂对低温熔块性能的影响

Influence of Lithia on Performances of Low Temperature Frit

本文研究了氧化锂加入量对低温熔块的熔融温度、力学性能、热膨胀系数的影响。研究表明:随着氧化锂加入量的增多,熔块的抗折强度、熔融温度和吸水率降低、熔融温度范围变窄、热膨胀系数增加。

The influences of lithia content on the melting temperature, mechanical properties and thermal expansion coefficient of low temperature frit were studied. The results showed that with the increase of lithia content, the melting temperature and water absorption decreased, the range of melting temperature became narrow, and thermal expansion coefficient increased.
