Abstract
A method and apparatus for hydrothermally growing crystals in a pressure vessel containing feed crystals immersed in a mineralizing solution. The apparatus is disposed in the pressure vessel, above the mineralizing solution. The apparatus includes an enclosure having opposing major walls with passages extending therethrough. The enclosure completely surrounds a seed plate having opposing major faces. A restraining structure holds the seed plate within the enclosure such that the major faces of the seed plate are spaced inwardly from the major walls.
Claims25
An apparatus for shaping a crystal grown from a seed crystal, said apparatus comprising:
- an enclosure for disposal around the seed crystal, said enclosure having a plurality of passages extending therethrough;
- and
- a retaining structure for holding the seed crystal within the enclosure.
An assembly for hydrothermally growing a crystal, said assembly comprising:
- a pressure vessel containing a basket filled with feed material and a mineralizing solution, said basket being immersed in the mineralizing solution;
- a rack having a mounting frame, said rack being disposed within the pressure vessel, above the mineralizing solution;
- a seed plate having opposing major faces;
- and
- an apparatus suspended from the mounting frame, said apparatus including:
- an enclosure that, when viewed in a cross section taken at a right angle to a longitudinal axis of the enclosure, completely surrounds the seed plate;
- and
- a retaining structure that holds the seed plate within the enclosure such that the seed plate is fully disposed within the enclosure.
An apparatus for shaping a crystal grown from a seed crystal, said apparatus comprising:
- an enclosure for disposal around the seed crystal, said enclosure having open ends and at least one passage extending therethrough, said passage being non-linear in a direction parallel to a cross-section of the enclosure taken at a right angle to a longitudinal axis of the enclosure;
- and
- a retaining structure for holding the seed crystal within the enclosure such that the seed crystal is substantially disposed within the enclosure.
