Physical Characterisation of Ceramics and Filter MediaThe porosity of ceramics and filter media is often inextricably linked to their performance in a wide range of applications. When selecting, assessing or producing ceramics and filter media it is necessary to consider the required porous characteristics with respect to the intended application. Changes in porosity also need to be considered during product use, especially with regard to capacity thresholds, pore blocking or fouling and product regeneration. The porous nature of raw material powders, together with manufacturing conditions, often dictate the ultimate pore size and volume of a finished product, and therefore its efficacy.
Key ApplicationsDetermination of pore size and volumeDetermination of absolute porositySelection and control of raw material constituentsFormulation and fabrication process control Identification of optimum fabrication conditionsSelection of materials for specific applicationsMonitoring of products for efficacy during useInvestigation product failure and performance issuesInvestigating product regenerationApplication to filtration of gaseous environmentsApplication to fluid environments and water treatment
Ceramics and filter media are applied to a very broad range of applications and are intended for exposure to a diverse range of operating conditions and interacting species, from gaseous molecules to fluid and water contaminants. Requirements of pore size, pore volume and specific surface area therefore cover a wide range are usually very demanding with respect to the absolute values. At MCA Services we offer a complete suite of analytical techniques which allows for the complete characterisation of porosity throughout the ranges of ultra-micropores (< 1nm diameter) through to macro-pores (up to 650 µm). When the ceramic or filter media is doped with a chemically active metallic component, chemisorption options become particularly useful. Chemisorption provides the means of analysing the active component alone for its surface area, crystallite size and, importantly, availability via its dispersion.
Key ApplicationsGas AdsorptionUltra-micropore analysis (< 1.0 nm)Micropore analysis (< 2.0 nm)Mesopore analysis (2 – 50 nm)Pore volume measurementPore size distribution measurement Specific surface area (BET) measurementSpecific probe gases availableMercury PorosimetryMercury intrusion and extrusion optionsMesopore & Macropore analysis (3.5 nm – 650 µm)Pore volume measurementPore size distribution measurementAbsolute porosity, bulk density and skeletal densityPermeability and tortuosity measurementCavity to throat size measurementHelium PycnometryAbsolute density measurementChemisorption and Temperature Programmed AnalysisApplication to active metal doped mediaActive component dispersion and surface areaReduction, oxidation and desorption temperature profiles
MCA Services offers a complete suite of techniques for the characterisation of material porosity throughout the range of micropores, through mesopores and macropores. We also have extensive experience and expertise to actively assist with the interpretation of results, relating porous characteristics to the sample material and its ultimate application in a battery system. Combined with state-of-the-art instrumentation and software, offering flexible and extensive reporting options, we help to maximise the amount of high quality data describing sample materials.
