The high temperature superconductor Hg Ba2 Ca(2-x) La(x) Cu3 O(10+d) compound for different values of pressure ( 4 and 6 ton/?cm?^2) was prepared by a solid state reaction method . It has been found that the specimens were superconductorsat p= 4 and 6 tons/?cm?^2also the transition temperature T_c= 145c^°is the maximum at (p =6 ton/?cm?^2 ) for x = 0.6 .X- ray diffraction showed a tetragonal structure with the variation of the lattice constant( c ) with increasing of the pressure .
