Abstract：
Aimed at the transformation methods and mechanism of amorphous silica on the conditions of high pressure and high temperature, we used the Changbaishan diatomite, which had been heating treated at 700°C, as the sample of amorphous silica, to carried out the in situ high pressure and high temperature synchrotron X-ray diffraction determinations (EDXD method) in the range of pressure of 0—4GPa and temperature of 1000—1300K by the diamond anvil cell apparatus and double-sided laser heating technique. The experimental results indicate that amorphous silica transform to α-quartz, but not β-quartz and cristobalite in the range of pressure of 0.8—2.4GPa and temperature of 1000—1300K. The crystalline temperature of amorphous silica under high pressure is much lower than that of ambient condition.The resluts means that the pressure is favored to low the activation energy of amorphous transform to crystalline phases,and would change the metastable phase transformation mechanism,leading to the different crystalline phases. In the range of pressure of 3—4GPa and temperature at 1300K, both amorphous silica and quartz transform to coesite.
