Method of growing quartz |
| abstract |
Quartz is grown from a quartz seed material by depositing electrodes onto the seed, heating the seed to about 500 degrees C. while applying an electric field along the Z-axis of the seed of a strength of about 2 kV/cm for about 72 hours, maintaining the electric field while the seed is cooled to room temperature, removing the electrodes from the cathode surface of the seed, etching the seed, placing the seed in an autoclave and hydrothermally growing quartz. |
