| 摘要 |
A crucible useful for continuous preparation of single crystals with selected crystal orientation or for depositing thin films of crystalline materials such as silica on substrates such as graphite by the pendant drop growth (PDG) method, the crucible base being tapped with one or more capillary bores having a length equal to or greater than the retention height of the molten liquid used to prepare the crystal of film at the temperatures and pressures used, the crucible being improved by "capping" its bottom with a conical baffle plate supported by feet on the bottom of the crucible, the improved crucible providing single crystals having high dimensional regularity and containing no bubbles or unmelted inclusions and the single crystals being broadly useful in jewelry, horology, and electronics. |
