Mercury intrusion porosimetry (MIP) is a suitable method for determining the pore size, particle size, bulk density and bulk density of solids and is described in ISO 15901-1. The liquid, non-wetting mercury is pressed into the porous or particulate system, whereby the applied pressure is inversely proportional to the pore size. Pore sizes from 3.6 nm to one millimetre can be detected in less than an hour. There is currently no alternative method. Other results from MIP include pore volume, specific surface area, size, fractal dimensions, compressibility and bulk modulus, tortuosity and more. This contribution will cover various aspects of mercury intrusion porosimetry, such as safe handling of mercury and easy recycling in the lab to minimise the amount of mercury used. In addition, applications and some special notes for the measurement of cement-based materials, pharmaceuticals, battery electrodes and separators, ceramics and more are presented and discussed.
