    • For ion exchange at the surface of glass or glass ceramic, the ion exchange is carried out by means of a solid layer containing mainly one or more salts which do not melt at the exchange temperature and contain mono- or divalent cations. The layer can be applied to the glass as a dispersion in water or as an organic dispersion medium. Preferably, its thickness is 0.02 to 2 mm and the salts have a particle size of less than 60 .mu.m. Despite the solid reaction, the ion exchange proceeds at a surprisingly rapid rate and leads to products having highly reproducible properties. Corrosive attack of the glass surface does not take place.
    • 为了在玻璃或玻璃陶瓷的表面进行离子交换,离子交换通过主要含有一种或多种盐的固体层进行,所述盐在交换温度下不熔化并含有一价或二价阳离子。 该层可以作为在水中或作为有机分散介质的分散体施加到玻璃上。 优选地,其厚度为0.02至2mm,并且所述盐的粒度小于60μm。 尽管有固体反应,但离子交换以令人惊讶的速度进行,并导致具有高度可重现性的产物。 玻璃表面的腐蚀性攻击不会发生。
