A method for determining the capillary porosity of the particles of disperse materials

摘要

Capillary porosity(the open porosity of the particles constituting a material of disperse system excluding the interparticle pore volume)should be taken into account in studying the particle-size distribution in a material [1-4]and the structure of porous systems[56-7], dis- perse systems[8,9], and colloids; in filtering, dehydrat- ing, and drying various materials[10-14]; and in designing a process for the synthesis of composite materials, including porous fillers. Capillary porosity is measured by mercury porosim- Etry.
