Abstract
A dried or at least partially dried ceramic feedstock, a method of preparing a dried or at least partially dried ceramic feedstock having a residual solvent content of up to about 15 wt. %, ceramic formulations comprising one or more ceramic precursors, temperature sensitive gelling agent, solvent, and having a viscosity suitable for low pressure injection molding, methods for preparing said ceramic formulations, a method of forming a ceramic article from said ceramic formulations, and a ceramic article obtainable therefrom.
Claims21
1-29. (canceled)
A method of preparing a ceramic feedstock comprising:
- preparing a ceramic slurry comprising one or more ceramic precursors, temperature sensitive gelling agent, and solvent, and
- treating the ceramic slurry under suitable conditions to obtain a dried or at least partially dried ceramic feedstock having a residual solvent content of up to about 15 wt. %, based on the total weight of the ceramic feedstock.
A method for preparing a ceramic formulation comprising:
- preparing a ceramic slurry comprising one or more ceramic precursors, temperature sensitive gelling agent, solvent;
- treating the ceramic slurry under suitable conditions to obtain an at least partially dried ceramic feedstock;
- mixing the at least partially dried ceramic feedstock with a suitable amount of additional solvent at a temperature above the gel point of the gelling agent to obtain a ceramic formulation having a viscosity suitable for low pressure injection molding.
