Abstract

Ultrafine particles of 0.01–10 µ and their preparation form the basis for a wide range of inorganic compounds which are utilized extensively in such fields as protective coatings, electronics, ceramics, paper, plastics, building materials, etc. Historically, the pigment industry has been a pioneer in this field extending their fine particle technology and products into many areas, other than coatings.

The metal oxides, and specifically those of iron, provide a versatile compound to demonstrate the growth of ultrafine particles. Various mechanisms and preparation techniques are described for producing ultrafine particles by solid state and liquid-solid state reactions. Processing variables such as temperature, time, impurities, concentration, nucleation, fluid dynamics, etc., are shown to have a profound effect on crystal growth. This can be demonstrated by studies of electron micrographs, surface areas, and particle shape and size distributions.
