Abstract
The various embodiments of the present invention are directed to wear resistant coatings, tiles having the wear resistant coatings disposed thereon, and to methods of making the coatings and tiles. A wear resistant coating generally includes a strontium aluminosilicate glass-ceramic composition that is formed from a glaze. The glaze can include a crystallizing component, which itself can include strontium, aluminum, and silicon, but also comprises less than about 2 weight percent each of lithium, boron, barium, sodium, iron, titanium, zirconium, and carbon, based on a total weight of the crystallizing component.
Claims16
A wear resistant coating, comprising a strontium aluminosilicate glass-ceramic composition that is formed from a glaze that comprises a crystallizing component, wherein the crystallizing component comprises strontium, aluminum, and silicon, and wherein the crystallizing component comprises less than about 2 weight percent each of lithium, boron, barium, sodium, iron, titanium, zirconium, and carbon, based on a total weight of the crystallizing component, wherein the glaze exhibits no detectable strontium aluminum silicate crystalline phase prior to firing;
- and
- wherein the glaze further comprises a flux component, wherein the flux component comprises aluminum, silicon, sodium, calcium, potassium, and magnesium, and wherein the flux component comprises less than about 2 weight percent each of lithium, boron, barium, iron, titanium, phosphorus, zinc, and carbon.
A coated tile, comprising:
- a ceramic tile;
- and a wear resistant coating disposed on a surface of the ceramic tile;
- wherein the wear resistant coating comprises a strontium aluminosilicate glass-ceramic composition that is formed from a glaze that comprises a crystallizing component;
- wherein the crystallizing component comprises strontium, aluminum, and silicon;
- and wherein the crystallizing component comprises less than about 2 weight percent each of lithium, boron, barium, sodium, iron, titanium, zirconium, and carbon, based on a total weight of the crystallizing component, wherein the glaze exhibits no detectable strontium aluminum silicate crystalline phase prior to firing;
- and
- wherein the glaze further comprises a flux component, wherein the flux component comprises aluminum, silicon, sodium, calcium, potassium, and magnesium, and wherein the flux component comprises less than about 2 weight percent each of lithium, boron, barium, iron, titanium, phosphorus, zinc, and carbon.
A wear resistant coating, comprising a strontium aluminosilicate glass-ceramic composition that is formed from a glaze that comprises a crystallizing component, wherein the crystallizing component comprises strontium, aluminum, and silicon, and wherein the crystallizing component comprises less than about 2 weight percent each of lithium, boron, barium, iron, titanium, zirconium, and carbon, based on a total weight of the crystallizing component;
- and
- wherein the glaze further comprises a flux component, wherein the flux component comprises aluminum, silicon, sodium, calcium, potassium, and magnesium, and wherein the flux component comprises less than about 2 weight percent each of lithium, boron, barium, iron, titanium, phosphorus, zinc, and carbon.
A wear resistant coating, comprising a strontium aluminosilicate glass-ceramic composition that is formed from a glaze that comprises a crystallizing component and a flux component, wherein the crystallizing component comprises strontium, aluminum, silicon, and wherein the crystallizing component and the flux component together comprise less than about 2 weight percent each of lithium, boron, barium, iron, titanium, and carbon, based on a total weight of the crystallizing component, wherein the glaze exhibits no detectable strontium aluminum silicate crystalline phase prior to firing;
- and
- wherein the flux component comprises sodium, calcium, potassium, and magnesium.
