Abstract
PURPOSE: To temper an Na salt-contg. glass product by bringing it into contact with a soln. of a boron-contg. K salt or a mixed soln. of the salt and other K salt and holding the product at a temp. near the strain point of the glass for a fixed time to carry out ion exchange of Na+ and K+.
CONSTITUTION: An Na salt-contg. glass product is dipped in a soln. of a boron- contg. K salt or a mixed soln. of the salt and other K salt or coated with the soln. and held at a temp. near the strain point of the glass for a fixed time to temper the glass product by ion exchange. By using the boron-contg. K salt, borate glass is formed once on the glass surface, and at the same time, the ion exchange is carried out. Thus, the K salt does not run away and scts effectively with hihg wettability to the glass. A soln. of potassium metaborate and/or potassium borate or a mixed soln. of the potassium salt and potassium nitrate is used, and the soln. may be neutralized.
