Abstract
The phase behaviour of carbon dioxide confined in VYCOR glass at press ures below that of the bulk triple point (similar to 0.51 MPa) has bee n investigated. The temperature at which freezing occurs appears to be pressure dependent below 0.3 MPa. As experiments are performed at suc cessively lower pressures, the confined phase transitions gradually di sappear, due to either partial pore filling, or the proximity of the c onfined triple point.
