Combustion Synthesis of Transition Metal Nitridesnaces and long reaction times. More innovative methods for the formation of refractory powders include the gaseous reaction of metal and non-metal ions in high temperature environments. Disadvantages of the former method are impure products and inefficient operation, while the latter method deals with complex reactions and expensive equipment.

Flocculation and Filtration of Colloidal Particleses. Colloid stability may arise from the fact that particles are charged and repel each other electrically or from the presence of adsorbed layers. These subjects and methods of reducing colloid stability have been discussed by Overbeek (this volume).

Preparation of Shaped Glasses Through the Sol-Gel Method controlled depending on the desired shape of the resulting glass. Larger water contents of the starting solution are preferred for the production of bulk glasses, while smaller water contents lead to the formation of fiber glasses. The cross-section of glass fibers made by the sol-gel method is cir
