Growth of Pore-less BaTiO3 Single Crystal by Solid State Reaction |
| 초록 |
BaTiO3 single crystals were grown from the dense ceramics made by Aerosol deposition method, using Solid State Single Crystal Growth method. [100] or [110] – oriented SrTiO3 seed crystals were adapted for grain growth. Solid State Single Crystal Growth (SSCG) has been intensively studied due to the low cost and compositional variations. However, the SSCG method also has some disadvantages, for instant, pores are trapped inside the single crystal. Pores are usually from the pores in ceramics for grain growth. Using Aerosol Deposition Method, BaTiO3 powder was deposited on SrTiO3 seed crystals. The film that has highly dense structure, no micro cracks or pores was made by AD Method. Then the film was annealed at 900℃ to 1300℃ for single crystals without pores to grow on the seeds. X-ray diffraction analysis shows that the single crystals was grown following the seed directions. Scanning electron microscopy (SEM) micrograph revealed that grain growth behavior depended on annealing temperature and heating rate. We confirmed that pore-less single crystal can be fabricated by AD Method. |
