Ceramics in the form of colloidal dispersions are used in a wide variety of products and applications, from polishing semiconductor wafers to forming corrosionresistant coatings. The dispersions are expected to retain their original properties for a specified period of time, which is often referred to as the product's shelf life or stability. A product that remains free from change or variation under acceptable environmental conditions for a specified period of time can be said to be stable.
Stability is important because if the size distribution of the dispersed particles changes, the resulting product will not meet the expected specifications. For example, if a ...
