11. A method for sealing, comprising:
positioning a valve within a wellbore tubular, the valve including;
a housing;
a sliding sleeve disposed in the housing and defining an annular flow path between the sliding sleeve and the housing, the sliding sleeve configured to move from a closed positioned closing the annular flow path to an open position opening the flow path; and
a plug member positioned within the flow path, the plug member comprising a metal configured to expand in response to hydrolysis to seal against the housing and occlude the annular flow path;
pumping cement within a wellbore tubular; and
subjecting the plug member to a reactive fluid, thereby forming an expanded metal plug member that seals against the housing and the sliding sleeve and occludes the annular flow path.
