Title: Green Body Density Measurement Techniques
Published: Date Unknown
Abstract: Green body density measurement techniques were investigated and compared. The measurement techniques investigated include mass-volume measurement, mercury pycnometry, powderdisplacement pycnometry, and noncontact ultrasonic method. Samples studied include green bodies prepared by uniaxial pressing and also from a commercial source.For well defined samples such as cylinders, discs and tiles, mass-volume method, mercury porosimeter and powder displacement pycnometry gave comparable bulk densities. For density gradient measurements, non-contact ultrasound method has the potential to be an on-line as well as a non-destructive quality control method.
