The Coloring Effect of Glasses by Ag+ Ion Exchange
Coloring effect, mechanical properties resulting from silver ions exchange of glasses immersed into the mixed molten salt of KNO3 and AgNO3 were investigated in this study. Ion exchange coloring of glasses made it possible to obtain glasses with a range from yellow to yellowish-brown, and spectral transmittance was investigated. The amount of ion exchange and peneration depth increased with treatment temperature and time. The activation energy decreased with mole fraction of AgNO3. It can be seem that the bending strength of ion exchanged glasses were 3~4 times higher than the parent glass and Ag+ colloids prevented from increasing surface microhardness.
