FINE CERAMICS (ADVANCED CERAMICS, ADVANCED TECHNICAL CERAMICS) - DETERMINATION OF SPECIFIC SURFACE AREA OF CERAMIC POWDERS BY GAS ADSORPTION USING THE BET METHOD (ISO 18757:2003, IDT)
This Malaysian Standard provides guidelines for the determination of the total specific external and internalsurface area of disperse or porous (pore diameter greater than 2 nm) fine ceramic materials by measuring the amount of physically adsorbed gas according to the method of Brunauer, Emmet and Teller (BET method). General guidelines of the method are described in ISO 9277. This Malaysian Standard only focuses on specific details relevant to fine ceramic materials. It should further be noted that the BET method cannot be applied to type I isotherms (microporous materials or chemisorption behaviour) or when the solid absorbs the measuring gas.
