The effects of baffle on the hyrothermal growth of quartz by temperature gradient method were investigated. The maximum growth rate was obtained with a 80% baffle closing in autoclave 3.5cm in inside diameter, but in 8cm inside diameter vessel, the rate of growth was greater with a 90% baffle than with a 80%. When the baffle plate was supported at the middle of tube, higher growth rate and greater uniformity of growth were obtained than that at one third position. In larger inside diameter autoclave, all the crysals grew at more nearly the same rate. Long-term growths of quartz under the best conditions in 48 hours experiments were done.
