Résumé
Nous avons étudié les caractéristiques des suspensions aqueuses de deux poudres de nitrure de silicium d'origines commerciales. Nous décrivons les propriétés chimiques, colloïdales et rhéologiques et la viscosité en fonction du pH de la teneur en défloculant et de la densité de la suspension.
Abstract
Properties of aqueous slips of silicon nitride were studied on two types of commercially available powders. Results are given of measurements of ζ-potential, critical coagulation coefficient and viscosity as a function of pH, concentration of deflocculant and solid-liquid ratio. Optimized slip casting conditions are given.
