Porous Materials, Inc. (PMI) has produced a chart that matches appropriate porosity characterization instruments and techniques to applications. Measurement and control of porosity in ceramics is critical in many diverse applications ranging from refractories to advanced fuel combustion systems. Important properties include largest pore size, mean pore size, pore distribution, gas and liquid permeability and system integrity. Testing techniques and instruments for characterizing porosity are based on different principles and, therefore, don't provide the same information. The proper selection of one or more techniques requires matching of the characteristics of the test and the requirements of the specific application.
