摘要

Kinetics of dissolution of quartz, its solubility and a heavy phase formation in Na_2CO_3 and NaOH solution under temperature 100 deg C, 200 deg C and 320 deg C and filling of autoclaves at 76/100 and 79/100 were studied. The etching surface of quartz bars after the runs is characterized. For the evaluation of entrapped solid inclusions and water-bearing nonstructural contaminations against the growth rate of quartz crystals, the accelerated method was developed.
