    Porosity Analyzer

    Overview Knowledge Standards Terms
    A porosity measuring instrument determines the ratio of the internal pore volume to the total volume of a material using gas adsorption or mercury intrusion porosimetry. It is used to evaluate the internal structural characteristics of materials and is applied in quality testing for catalysts and building materials.
    Selection
    When selecting, consider the matching of sample characteristics with the measurement principles. The gas adsorption method is suitable for microporous materials, while the mercury intrusion method is suitable for macroporous materials. Verify that the instrument's measurement range covers the pore size range of the sample to ensure that the measurement accuracy meets the requirements of the testing standards.

    Porosity Control in the Preparation of Porous Coatings During the Blade Coating Process
    Doctor blade coating is a wet coating technique widely used for preparing functional coatings, which involves uniformly applying a slurry containing solid particles (such as ceramics, polymers, or metal oxides) onto a substrate, followed by drying and heat treatment to form the coating.
