a solution containing 88 g/L of sodium carbonate and sealed. The simple furnace used consists of a hotplate on which the autoclave stands surrounded by micaceous-flake thermal insulation. By this means a temperature gradient is established so that it is hotter at the bottom in the region of the nutrient crushed quartz than at the top where the seeds are located. Under the working conditions, the autoclave is filled with a single-phase fluid. The pressure developed being a function of the

The Abstract The analysis of the impurity content crystals grown in sodium carbonate solution is carried out using flame technique. Colored crystals have been produced from aqueous solutions of potassium carbonate under laboratory conditions and using a steel autoclave. The seeds were slices cut parallel to the planes (0001). With the impurity of aluminum and irradiation, defective color centers have generated quartz coloration phenomenon. This is occurred on the base of the electrical balance by exchanging aluminum ions with tetravalent silicon ions in the presence of alkali elements (monvalent) i.e. Na + or Li + . Interestingly, the current paper introduces a method suggests the utilization of silica-rich rocks to develop the growth of large crystals of synthetic quartz.
