Abstract
A method of manufacturing articles that consist of a material in which one or more crystalline phases in a finely dispersed condition are surrounded by a glassy phase, in which the articles are first formed from a glass melt in a manner commonly used in The technology of glass, glass melt consisting of the components Li2O, MgO, Al2O3, and SiO2, contains P2O5 as nuciente agent of crystallization and in addition ZrO2, after which the glass articles thus formed are heated within a range of temperature in which the crystallization nuclei are formed and then heated in a temperature range in which the crystalline phases grow until the desired degree of crystallization is obtained, characterized in that the melt of the glass has the following composition: SiO2 65-75% by weight Al2O3 10-25% by weight Li2O 5-10% by weight MgO 0-5% by weight contains P2O5 in an amount of 2.5 to 7% by weight and, as, a second crystallization nucleating agent, contains 2rO2 in an amount of 0.5 to 2.5% by weight and that the entire glass product is heated first in a temperature range between 600 and 800ºC and then in a temperature range between 800 and 1050ºC.
