Abstract

Commercially available silicon nitride powders were coated with various metal oxides with the help of metal-organic surfactants in an aqueous medium. A surfactants could also act as a dispersant. The coatings were studied by XPS, TEM and accoustophoresis and the mechanism for formation of these coatings is proposed. The amount of sintering aid incorporated was determined by the surface area and surface chemistry of the nitride powder, the pH of the solution, the structure of the surfactant and the surface charge behavior of the powder and the coating. Multicomponent coatings were also possible by precise control of these parameters. The sintering behavior of the coated powders and the properties of the sintered material were promising.
