Abstract
A molding composition is provided that includes an inorganic component, an organic binder component, and a debinding catalyst. The molding composition is capable of lowering the sintering temperature, for example, when the molding composition is used to make ceramic microstructures such as barrier ribs for plasma display panels.
Claims8
A molding composition comprising:
- an inorganic component including a glass or ceramic powder;
- an organic binder component capable of being hardened by exposure to heat, light, or an electron beam;
- and
- a debinding catalyst of the organic binder component, the debinding catalyst comprising Co(NO3) or a transition metal oxide, salt, or complex wherein the transition metal is different from copper,
- wherein the molding composition has a sintering temperature that is at most about 500° C., and wherein the presence of the debinding catalyst in the molding composition enables the use of lower sintering temperature ceramic formulations.
