Crush strength measures the resistance of a solid to compression, a property of paramount importance not only for industrial catalysts, but also for ceramics, pharmaceutical tablets and many other solid materials.
CRUSH-BK and CRUSH-SP are dynamometers of general use for compression measurements. As far as catalysts are concerned, the ASTM standard methods ASTM D4179 and ASTM D6175 are recommended.ASTM D4179 refers to tableted pellets, which can be measured in either axial or radial way. As the axial crush strength is much higher, it is not representative of the …

Statistics and experiments reveal that the mechanical failure of a spherical catalyst under single-particle crushing strength and bulk crushing strength tests are both brittle fracture and the fact that the single particle strength data follow a Weibull distribution. A model is proposed for the packing of spherical particles, which assumes tetrahedral contact and force …
