Bi_(2)O_(3)含量对R_(2)O-Bi_(2)O_(3)-B_(2)O_(3)-SiO_(2)系低熔玻璃性能的影响

Effect of Bi_(2)O_(3) on Properties of R2O-Bi_(2)O_(3)-B_(2)O_(3)-SiO_(2) Low Melting Glass

笔者采用高温水淬法制备了R_(2)O-Bi_(2)O_(3)-B_(2)O_(3)-SiO_(2)系低熔玻璃,且研究了玻璃结构、热膨胀系数和耐酸性能。其结果表明,随着Bi_(2)O_(3)含量的增加,玻璃的拉曼散射峰强度逐渐减弱,热膨胀系数逐渐增强,耐酸性能逐渐减弱。

R_(2)O-Bi_(2)O_(3)-B_(2)O_(3)-SiO_(2)low melting glass was prepared by high temperature water quenching method.The glass structure,thermal expansion coefficient and acid resistance were studied.The results show that with the increase of Bi_(2)O_(3)content,the intensity of all Raman scattering peaks gradually decreases.The thermal expansion coefficient gradually increases,and the acid resistance gradually decreases.
