Hydrothermal syntheses were made mainly in the binary system SiO2-H20 in a temperature range between 300 ~ C and 500 ~ C and pressures from 0.2 kbar up to 4.0 kbar with various starting materials. In this way the transformation behavior of different amorphous silicas via cristobalite and keatite to
