Compression equations for mercury porosimetry
Abstract
Methods for obtaining isothermal pressure-volume data using a mercury porosimeter and for completely correcting this data for compression effects are described. The isothermal compressions of several liquids were measured with a 103 MPa (15,000 psi) mercury porosimeter using the principles described. The porosites and surface areas of several areas of several macroporous solids were accurately measured.
