Abstract
Some ceramic parts (e.g. electro-ceramics) are produced in high numbers and they need to be transported in the green state. During the handling before firing the ceramic green body has to withstand mechanical loading. Therefore a minimum strength is required. A lot of effort has been made in recent years to establish methods for characterising ceramic green bodies, particularily for measuring the green strength.
For this investigation ceramic green bodies were pressed uniaxially and their strength was measured. Data acquired from cylindrical samples using the Brazilian disc test were compared with bending test results on large specimens. In the Brazilian disc test the influence of sample size and loading rate on the measured strength values was investigated. Test results can also be used to analyse the influence of binder type and content on the green strength.
