A process of purifying crystalline quartz to remove impurities within the lattice structure comprising the steps of heating the quartz to the tridymite polymorphic form and evaporatively reacting the heated quartz with an aqueous acid solution reactive with the impurities in the quartz to form water soluble metal salts. The residue of the evaporative reaction is washed with water to dissolve the metal salts leaving purified crystalline quartz. The disclosure also includes the product of the process.

Um processo de purifying o quartzo cristalino para remover as impurezas dentro do lattice estrutura compreender as etapas de aquecer o quartzo ao formulário polymorphic do tridymite e evaporativa de reagir o quartzo aquecido com uma solução ácida aqueous reactive com as impurezas no quartzo para dar forma a sais soluble do metal da água. O resíduo da reação evaporativa é lavado com água para dissolver os sais do metal que saem do quartzo cristalino purified. A divulgação inclui também o produto do processo.
