Precipitation and Crystallization Processes

and crystallization processes the same basic steps occur: supersaturation, nucleation and growth. Nucleation does not necessarily begin immediately on reaching a supersaturated condition, except at very high supersaturation, and there may be an induction period before detection of the first crystals or solid particles.

How Do Ultrasonic Transducers Work

Apr 08, 2013 Transducers are special instruments that have the ability to turn one energy type into another. A transducer is a vital component of sonography or ultrasonic imaging. In sonography, the camera is a transducer. When an electric charge is applied to the camera, the camera converts this energy into vibrations. This is known as piezoelectric effect.

Jan 13, 2020 Crystallization is the solidification of atoms or molecules into a highly structured form called a crystal. Usually, this refers to the slow precipitation of crystals from a solution of a substance. However, crystals can form from a pure melt or directly from deposition from the gas phase. Crystallization can also refer to the solid-liquid ...

What Is a Crystal and How Does It Form? - Sciencing

Jul 21, 2017 Natural crystals that come from the Earth form the same way. These crystals were formed over a million years ago inside the Earth's crust. They occur when the liquid in the Earth consolidates and the temperature chills. Other crystals form when the liquid makes its way through the clefts and dispense minerals into the clefts.
