Moder Solution for Safe Debinding of Ceramic Parts

Technical ceramics are manufactured in powder-based production processes. The ceramic powder component is formed via various manufacturing steps and is finally sintered. Organic binders are applied to ensure cohesion of the powders during and after shaping. They are used, for example, for the injection molding process, isostatic presses, hot presses, slip casting, tape casting, extrusion and numerous additive manufacturing processes. The binder needs to be removed before sintering, a step which is commonly referred to as debinding. When debinding oxide ceramics like alumina or zirconia, the binder can be thermally. combusted in the presence of air. For non-oxide ceramics, a constant flow of inert gases are required for debinding. During thermal debinding or pyrolysis, gaseous hydrocarbons are released. These form an explosive mixture when concentrated in the furnace chamber which has led CARBOLITE GERO to develop sophisticated safety concepts for safe debinding.
