Abstract
Method of manufacturing objects that consist of a material in which one or more crystalline phases in a finely dispersed form are surrounded by a glassy phase, in which the objects of a glass melt are first formed according to a method known in the art. manufacture of glass, said melt containing the constituents Li2O, Al2O3 and SiO2 and furthermore at least one crystallization catalyst, after which the glass objects thus formed are heated in a temperature range in which crystallization nuclei are formed and finally in a temperature range in which the crystalline phases grow until the desired degree of crystallization is reached, characterized in that the glass objects formed, before being subjected to the thermal program crystallization products, are heated to a temperature comprised between 400 and 700ºC in a humid atmosphere that contains ZO2 and then they are washed until a rarefacciº is reached In such a lithium layer in a surface layer of the object, said surface layer already exhibits crystallization during the subsequent heat treatment.
