Abstract
Glass or crystal particles of nanocrystalline size having a minor dimension of 0.1 to 100 Angstrom units. They may be prepared by controlled thermal separation of phase-separable glasses. Preferred crystal forms are zinc pyrophosphate and lithium disilicate. A crystallizable glass is combined with phyllosilicate particles and sintered to form an oriented composite body. During slow sintering, the crystal grows epitaxially on the phyllosilicate.
