Pores exert a dominating influence on the mechanical and thermomechanical properties of refractory material such as strength and thermal shock behavior. Thus, it is essential to characterize and quantify their number, size and size distribution.

Mercury intrusion porosimetry (MIP) is an analytical technique used to characterize the material's porous nature relating to the pore diameter distribution, total pore volume, bulk and apparent density. The technique involves the intrusion of non-wetting mercury into the sample as a function of pressure whereby the measurement can be extended by an extrusion process or even a cycling of intrusion and extrusion. Quite a lot of publications using the mercury intrusion/extrusion porosimetry have in common that specifics of the measuring parameter are not provided. This complicates the replication of studies for interested scientists. Measuring parameters can affect mercury intrusion/extrusion porosity results. They are even more relevant when performing combined intrusion/extrusion studies due to a large impact of the measuring parameters on the extrusion step. Therefore, this study attempts to provide an overview of the influence of the measuring parameters on the mercury intrusion/extrusion porosimetry results. The specific parameters are the stem and bulb volume of the penetrometer, equilibrium time, data analysis options, sample/particle size and sample amount.

孔对耐火材料的机械和热机械性能（例如强度和热冲击行为）产生主要影响。因此，表征和量化其数量，尺寸和尺寸分布至关重要。

汞侵入孔隙率法（MIP）是一种分析技术，用于表征与孔径分布，总孔体积，体积和表观密度有关的材料的多孔性。该技术涉及作为压力的函数将非湿润的汞侵入样品，从而可以通过挤出过程甚至侵入和挤出循环来扩展测量范围。许多使用汞压入/压出孔隙率法的出版物的共同点是未提供测量参数的细节。这使感兴趣的科学家重复研究变得复杂。测量参数可能会影响汞侵入/挤出孔隙率结果。当执行组合的入侵/挤压研究时，由于测量参数对挤压步骤的巨大影响，它们甚至更加相关。因此，本研究试图概述测量参数对水银压入/压出孔隙率法测量结果的影响。具体参数是针入度计的茎和球体积，平衡时间，数据分析选项，样品/粒径和样品量。
