ABSTRACT:
Single crystals consisting of various compositions from the quaternary silicate system Al.sub.2 O.sub.3 --CaO--MgO--SiO.sub.2 are grown from the melt. The physical and chemical properties of the single crystal silicates, including akermanite (Ca.sub.2 MgSi.sub.2 O.sub.7), cordierite (Mg.sub.2 Al.sub.4 Si.sub.5 O.sub.18), and mullite (Al.sub.6 Si.sub.2 O.sub.13), make the silicates useful, for example, as substrates for epitaxial semiconductor films.
