Abstract:
Transition metal NZP type compounds are synthesized. Examples of these compounds include MnZr4(PO4)6, FeZr4(PO4)6, CoZr4(PO4)6, NiZr4(PO4)6, and CuZr4(PO4)6. These compounds are synthesized by the Xerogel process. These transition metal NZP type compounds can be used as colorants in applications such as ceramic glazes where high thermal stability of the colorant is important.
Abstract:
A composite material suitable for labeling a substrate. The composite material, which is preferably a ceramic composite, comprises a fired ceramic body and a layer thereon. The fired ceramic body includes a base layer that comprising a glassy phase and a refractory phase, the glassy phase being capable of wetting a substrate at an application temperature. There is sufficient color contrast between the top layer and the fired ceramic body such that a code pattern (e.g., a bar code) present (or formed) is optically discernible. Methods of making and using the same are also taught.
Abstract:
The present invention provides a new and useful enamel composition and method of using the same for producing an enamel finish on a formed section of glass. The enamel composition partially crystallizes upon heating, thereby helping to prevent the forming and handling equipment from sticking and/or adhering to the composition during the forming operation. The enamel composition includes a crystallizable glass frit portion and a seed powder. The crystallized glass frit portion includes precursors from which Zn2SiO4 can be crystallized upon firing of the enamel composition. The seed powder causes at least a portion of the precursors to crystallize upon firing such that during firing at least a part of the crystallizable glass frit yields crystallized Zn2SiO4 formed by the precursors. Preferably, the precursors comprise ZnO and SiO2, and the seed powder comprises crystalline Zn2SiO4. The enamel composition also preferably includes bismuth oxide (Bi2O3) in order to help further ensure that no sticking and/or adhering problems develop during the forming operation.
