【摘要】 采用二步法化学强化工艺,制备经5组不同配比的混合熔盐化学强化处理的锂铝硅玻璃,研究第一步强化（IOX1）熔盐配比对玻璃化学强化性能的影响。结果表明,随着IOX1熔盐中NaNO₃浓度的降低,IOX1处理后表面压应力CS₃0值和强化膨胀率减小,主要是受熔盐中Na⁺浓度降低以及Na⁺/Li⁺离子交换量减少的影响。随着IOX1熔盐中NaNO₃浓度的降低,KNO₃浓度的升高,第二步强化（IOX2）后CS_K值和DOL_K值逐渐增加,表明IOX1在玻璃中形成的高浓度Na⁺并未促进IOX2中K⁺/Na⁺交换量,形成的K⁺会增加IOX2中K⁺/Na⁺交换深度。更多还原

【Abstract】 In the present paper,lithium aluminosilicate glasses were chemically tempered in five different ratios of molten salts by two-step tempered process to investigate the effect of ratio of IOX1 mixed molten salts on tempered performance.The experimental results revealed that CS₃0 value and tempered expansion rate after IOX1 treatment decreased with decreasing NaNO₃ concentration in IOX1 salt solutions,that was mainly caused by the decrease of Na⁺concentration and Na⁺/Li⁺ion exchange capacity.CS_K and DOL_K value gradually increased with decreasing NaNO₃ and increasing KNO₃ concentration of IOX1 salt solutions,indicating that high Na⁺ concentration in glass treated in IOX1 doesn’t promote K⁺/Na⁺ exchange capacity in IOX2,while K⁺ in glass treated in IOX1 increases K⁺/Na⁺exchange depth after treatment in IOX2.更多还原
