Abstract
Official abstract text for this publication.
The invention relates to a glass ceramic comprising article, wherein the integral, non-post-processed and non-reworked glass ceramic comprising article comprises at least three different types of microstructures. The microstructures differ in the number and/or size of the crystallites contained per unit volume, and/or in the composition of the crystallites, and/or in the composition of the residual glass phases. The different microstructures are characterized by different relative ion content profiles across a cross-section perpendicular to the transition areas. The relative ion content profiles are determined from intensities which are determined using secondary ion mass spectrometry, and each of the three different types of microstructures preferably has different intensity plateaus for individual ions, wherein the individual ions are components of the main crystal phases.
First claim
Opening claim text (preview).
The invention claimed is: 1. A glass ceramic comprising article, comprising: an integral, non-post-processed and non-reworked glass ceramic comprising at least three different microstructures; wherein said at least three different microstructures differ in a property selected from the group consisting of a number of crystallites contained per unit volume, a size of the crystallites contained per unit volume, a composition of the crystallites, and a composition of residual glass…
