Experimental determination of the relationship among baffle, temperature difference and power for the hydrothermal growth of quartz

Experimental determination is reported of the relationship among baffle design, the temperature difference between the growing and dissolving chambers, and the power requirements. Increasing the opening of the baffle requires a higher power level to maintain a given temperature difference. The presence of lascas or grown crystals, and the type of baffle used, have strong effects on the temperature difference-power curve. Growing-chamber temperature and top insulation have only minor effects
