title: Particulate characterization by ultrasound.
abstract: Ultrasound is a technique that is capable of tremendous accuracy and precision, whether in the laboratory or on-line in the factory. Data acquisition rates of the order of kHz transform process monitoring, providing unprecedented information of high statistical value. Ultrasound is complementary to other measurement modalities, probing the elastic and thermal properties of materials. In the absence of air bubbles, ultrasound travels through concentrated systems of particles, providing information about size, compressibility, structure, distribution, chemical and phase state. It is safe, can be non-invasive and can be economical. In these respects, it is unique.
