Abstract
The present invention includes a method of preparing a ceramic precursor article, the ceramic precursor made thereby, a method of making a ceramic article and an article made by that method. It also includes a method of replicating a ceramic shape.
Claims18
A ceramic precursor article having a predetermined shape, said article comprising alternately deposited layers of (1) a ceramic precursor powder comprising from about 50% to about 80% clay, from about 5% to about 20% feldspar, from about 2% to about 10% refractory cement, from about 2% to about 10% frit, and from about 0.5% to about 4% sodium silicate and (2) a binder comprising water and polyvinyl alcohol, in a pre-determined pattern, such that said ceramic precursor article is of said predetermined shape.
A method of preparing a ceramic article of a desired final shape comprising:
- (a) alternately depositing layers of (1) a ceramic precursor powder comprising from about 50% to about 80% clay, from about 5% to about 20% feldspar, from about 2% to about 10% refractory cement, from about 2% to about 10% frit, and from about 0.5% to about 4% sodium silicate and (2) a binder comprising water and polyvinyl alcohol, in a pre-determined pattern so as to form a ceramic precursor article of a precursor shape from a plurality of said layers, and
- (b) subjecting said ceramic precursor article to heat for sufficient time to form a ceramic article of said desired final shape.
