Effect of pressure and temperature on C₆₀ fullerite

663-667Simple model has been developed to study the effect of pressure and temperature on C60 solid. Pressure and temperature dependence of volume V/V0, bulk modulus B, and coefficient of volume thermal expansion α has been investigated by varying the temperature from room temperature to 2000 K, and pressures from room pressure to 200 kbar. The results have been compared with the available experimental data as well as different theoretical approaches. The good agreement between theory and available experimental data supports the validity of the simple model proposed for C60 solid
