Claims
- 1. A ceramic-binder composition suitable for shaping into a green body, said ceramic-binder composition comprising a polyalkylene carbonate and a ceramic powder, wherein the polyalkylene carbonate is present in the ceramic-binder composition in an amount from 0.5 wt% to 15 wt% and the polyalkylene carbonate and ceramic powder are admixed.
- 2. The ceramic-binder composition of claim 1, wherein said polyalkylene carbonate is polypropylene carbonate.
- 3. The ceramic-binder composition of claim 1, wherein said polyalkylene carbonate is polyethylene carbonate.
- 4. The ceramic-binder composition of claim 1, wherein said polyalkylene carbonate is in a solution of an organic solvent and the polyalkylene carbonate.
- 5. The ceramic-binder composition of claim 4, wherein said organic solvent is methylene chloride.
- 6. The ceramic-binder composition of claim 1, wherein said polyalkylene carbonate is in an emulsion of the polyalkylene carbonate with water.
- 7. The ceramic-binder composition of claim 1, wherein said polyalkylene carbonate is in an emulsion of the polyalkylene carbonate with an alcohol.
- 8. The ceramic-binder composition of claim 1, wherein said ceramic powder is selected from the group consisting of alumina, silica, titania, zirconia, cordierite, forsterite, titanates, ferrites, steatite, silicon carbide and silicon nitride.
- 9. The ceramic-binder composition of claim 2, wherein said ceramic powder is selected from the group consisting of alumina, silica, titania, zirconia, cordierite, forsterite, titanates, ferrites, steatite, silicon carbide and silicon nitride.
