Abstract
Methods and apparatus for synthesizing diamond from a carbon solution are provided. A carbon solution comprising dissolved carbon and liquid solvent is positioned in a levitation volume. Levitation is facilitated by performing the methods in microgravity. The levitation volume can have a dissolution zone and a diamond growth zone at different temperatures, or the temperature of the levitation volume can be adjusted between different periods. Apparatus are provided with one or more levitation generators which define a levitation volume and temperature control systems and devices. Diamond materials having sizes and properties suitable for a variety of applications are also provided.
Claims22
A method of synthesizing diamond, the method comprising;
- levitating a carbon solution comprising dissolved carbon and liquid solvent;
- controlling the temperature of the carbon solution so that the liquid solvent becomes saturated or supersaturated with the dissolved carbon;
- and
- precipitating the dissolved carbon from the liquid solvent to form a diamond precipitate.
An apparatus for synthesizing diamond from a levitating carbon solution comprising dissolved carbon in a liquid solvent, the apparatus comprising:
- a levitation generator configured to apply levitating forces to the liquid solvent, wherein the applied levitating forces define a levitation volume;
- a carbon source feed device at an end of the levitation volume;
- and
- a temperature control device configured to adjust a temperature of the levitation volume.
