A glass-ceramic plate for covering or accommodating at least one heating element, wherein the plate is at least partly coated with at least one nanoscale layer based on a metallic material having a refractive index greater than the refractive index of the glass-ceramic.
First claim
Opening claim text (preview).
The invention claimed is: 1. A glass-ceramic plate to cover or accommodate at least one heating element, wherein said plate is at least partly coated with at least one nanoscale layer based on a metallic material having a refractive index greater than the refractive index of the glass-ceramic and wherein the nanoscale layer comprises at least 95% by weight of the metallic material. 2. The glass-ceramic plate according to claim 1 , wherein the nanoscale layer serves as an underlayer for another layer. 3. The glass-ceramic plate according to claim 1 , wherein the nanoscale layer is combined with at least one paint layer. 4. The glass-ceramic plate according to claim 1 , wherein the nanoscale layer is combined with at least one enamel layer. 5. The glass-ceramic plate according to claim 1 , wherein the nanoscale layer is obtained by screen printing. 6. A process for manufacturing the glass-ceramic plate according to claim 1 , comprising applying a composition comprising at least one metallic material with a refractive index greater than at least one of the refractive index of the glass-ceramic and the refractive index of a precursor of said metallic material, and optionally an organic material for bonding the particles of said metallic material to the plate, to the precursor glass before ceramization. 7. A high-temperature-maintaining appliance, a cooking appliance, or a combination thereof, comprising the glass-ceramic plate according to claim 1 and one or more heating elements. 8. The glass-ceramic plate according to claim 1 , serving as a cooking plate or hob. 9. The process according to claim 6 , comprising screen printing a composition comprising at least one metallic material with a refractive index greater than at least one of the refractive index of the glass-ceramic and the refractive index of a precursor of said metallic material, and optionally an organic material for bonding the particles of said metallic material to the plate, to the precursor glass before ceramization. 10. The glass-ceramic plate according to claim 1 , wherein the nanoscale layer based on a metallic material has a refractive index of at least 1.77. 11. The glass-ceramic plate according to claim 1 , wherein the nanoscale layer based on a metallic material has a refractive index of at least 1.85. 12. The glass-ceramic plate according to claim 1 , wherein the nanoscale layer based on a metallic material has a refractive index of at least 2. 13. The glass-ceramic plate according to claim 1 , wherein the nanoscale layer based on a metallic material has a refractive index of at least 2.9. 14. The glass-ceramic plate according to claim 1 , wherein the layer is a screen printed layer.
