HYDROTHERMAL GROWTH OF CRYSTALS OF LaAlO3

reportActive / Technical Report | Accession Number: AD0614229 | Open PDF

Abstract:

LaAlO3 has been successfully grown in a hydrothermal system below and above the transition temperature of 435C. Using small autoclaves, growth has been observed in the temperature range of 400C - 600C in 7 m K2CO3 at 10,000 to 20,000 psi. A high pressure form of LaOH3 is also stable within this temperature and pressure range. Seed crystals up to 14 inches x 14 inches x 1 8 inches were grown from PbF2 fluxes. These crystals are readily doped with Cr by the addition of Cr2O3 to the melt.
