Abstract
The present invention provides an on-line method for stabilizing surface compressive stress of chemically-tempered glass, which comprises the steps of: placing glass to be tempered together with a stabilizer in a tempering furnace containing a molten salt bath for glass tempering; and after reacting at a temperature for a period of time, removing the glass and the stabilizer from the tempering furnace. The stabilizer is capable of chemically reacting with impurity ions in the molten salt bath for glass tempering, to remove the impurity ions in the molten salt bath. Therefore, the presence of the stabilizer allows the impurity ion content in the molten salt bath for glass tempering to be stable without gradual accumulation.
