摘要：

Solid-state epitaxial growth has been demonstrated by forming a thin film of an alumina sol on a single-crystal alumina and firing. Single-crystal and polycrystalline alumina were used here as substrates upon which boehmite sol was deposited by spin coating. The substrates were then dried and fired and characterized by powder X-ray diffraction and scanning electron microscopy. Films on sapphire single crystals showed highly oriented growth while the films on polycrystalline alumina substrates showed random orientation. © 1990.
