Strengthening molten salt for chemical strengthening of glass and use method of strengthening molten salt

The invention provides strengthening molten salt for chemical strengthening of glass. The strengthening molten salt is prepared from 50-70 wt% of potassium salt, 30-50 wt% of sodium salt and 0.05-0.25 wt% of lithium salt. The use method comprises the following steps: preparing the reinforced molten salt according to the proportion, and heating and dissolving; the method comprises the following steps: putting to-be-strengthened glass ceramics into strengthened molten salt, strengthening according to a strengthening process, testing the concentration of lithium ions after strengthening is completed, and then properly adding a lithium removal agent and an adsorbent according to the measured concentration to control the concentration of lithium. According to the invention, the size expansion of the glass can be actively controlled by adjusting the lithium content in the fused salt, so that the size change of the lithium aluminosilicate microcrystalline glass in chemical strengthening is controlled. 本发明提供了一种玻璃化学强化
