摘要: By using an X ray diffraction technique the compression of stishovite under hydrostatic pressure was studied to 10 GPa (100 kbar). The linear fits for cell edge and volume compressions are as follows: (1 - a/a0)/P = (1.31 ± 0.11) × 10−3 GPa−1; c/c0)/P (0.57 0.22) V/V0)/P (3.17 0.17) (Δc/c0)/(Δa/a0) 0.44 0.17. zero-pressure bulk modulus is 288 13 based on a derivative 6 1. This in agreement with Bassett Barnett (1970) Chung (1974).
