HIGH-PERFORMANCE GLASS CERAMICS AND METHOD FOR PRODUCING HIGH-PERFORMANCE GLASS CERAMICS

摘要

The present invention relates to a glass-ceramic-containing article in which an integral glass-ceramic-containing article that has not been subjected to post-treatment and reprocessing comprises three or more different microstructures. The microstructure differs in the number and / or size of the microcrystals contained per unit volume and / or the composition of the microcrystalline and / or the composition of the residual glass. The different microstructures (1, 2, 3) are characterized by different relative ion content profiles for the cross section perpendicular to the transition region. The relative ion content profile is determined from the intensities measured by secondary ion mass spectrometry and preferably each of the three or more different types of microstructures has a different intensity flatness for the individual ions, Lt; / RTI
