Abstract
A polycrystalline shaped article useful as a light-transmitting body or scintillation phosphor is formed from an essentially moncrystalline melt-grown macrocrystal ingot by pressing the ingot between opposed surfaces with no radial restraint, at a temperature below its melting point and under sufficient pressure to transform the ingot, in situ, into a fully dense, homogeneous, polycrystalline mass of unrestricted width. A polycrystalline shaped article useful as a light-transmitting and/or light-generating body may also be formed from a fully dense, homogeneous, optically integral polycrystalline mass by pressing the polycrystalline mass between opposed surfaces with no radial constraint, at a temperature below its melting point, but greater than one-half its melting point measured in degrees centigrade, under sufficient pressure to form a relatively larger polycrystalline mass of lesser height.
