Abstract: A crystalline SiO2-modification, which is characterized by an X-ray diffraction diagram having certain diffraction lines, and a process for the preparation of this crystalline SiO2-modification by crystallizing reactive amorphous SiO2under hydrothermal conditions in the presence of hexamethylenediamine. Sodium ions, phosphate ions and/or sulfate ions may be added for the crystallization.
