ResumoLithium silicates were synthesized by a precipitation method with a Li/Si molar ratio of 4:1. The powders synthesized were mixtures of lithium silicates, Li2SiO3 and Li4SiO4. Solids were characterized by X-ray diffraction. One of these samples was prepared with an abnormal crystallization pattern. However, the crystallization pattern was corrected after irradiation either with neutrons or with gamma radiation. Furthermore, there was a phase transformation, Li4SiO4 was the product found when Li2SiO3 and lithium atoms, held in its structure, reacted by the radiolysis reaction.
