Abstract
A transparent body can include a layer of a ceramic material and a compound. The compound can fill a defect extending from an edge of the layer, seal the edge, or both. In an embodiment, the edge is ground and is not polished. The compound can help to keep defects from propagating, improve fracture toughness, and reduce the likelihood that a crack will form during subsequent fabrication or use of the transparent body. Thus, the transparent body can be more scratch resistant than glass, such as cover glass, and still have acceptable resistance to cracking. The transparent body can be formed using a method where a compound precursor solution is applied to the edge, and the compound precursor solution is reacted or cured to form the compound.
