摘要
在活塞 圆筒式高压装置上研究了BaCuO2 .5在 4.5GPa内的p V关系 ,给出了其状态方程、Gr櫣ｎｅｉｓｅｎ参数γ0 、零压体弹模量B0 以及B0 的压力导数B′0 。并在金刚石压砧装置 (DAC)上测量了样品的电阻、电容随压力变化的关系 ,结果表明在 0～ 2
p-V relationship for BaCuO 2.5 at room temperature and in the pressure range up to 4.5 GPa was obtained using a piston-cylinder type device.Its equation of state,Grüneisen parameter γ 0,bulk modulus B 0,and the first order pressure derivative of B 0 were also acquired.The resistance versus pressure (R-p),and capacitance versus pressure (C-p) relationships up to 20 GPa were simultaneously studied using DAC at room temperature.The results showed that no phase transition occurred under pressure up to 20 GPa.
