Abstract
An article comprises a body having a coating. The coating comprising a eutectic system having a super-lattice of a first fluoride and a second fluoride. The coating includes a glaze on a surface of the coating, the glaze comprising the eutectic system having the super-lattice of the first fluoride and the second fluoride.
Claims14
A method comprising:
- mixing a first fluoride having a first melting temperature with a second fluoride having a second melting temperature that is lower than the first melting temperature to form a mixture comprising the first fluoride and the second fluoride;
- melting the first fluoride and the second fluoride by heating the mixture of the first fluoride and the second fluoride to a first temperature above at least the second melting temperature;
- cooling the mixture to form a material comprising a eutectic system having a super-lattice of the first fluoride and the second fluoride, wherein the eutectic system has a third melting temperature that is below the first melting temperature and the second melting temperature;
- grinding the material comprising the eutectic system into a powder;
- forming an article or a coating using the powder;
- and
- heating the article or the coating to a second temperature that is below the first melting temperature, below the second melting temperature and above the third melting temperature to cause at least a portion of the article or the coating to transform into at least one of a glaze or a glass ceramic comprising the eutectic system.

A method comprising:
- mixing a first fluoride having a first melting temperature with a second fluoride having a second melting temperature that is lower than the first melting temperature to form a mixture comprising the first fluoride and the second fluoride;
- forming a molten mixture of the first fluoride and the second fluoride by heating the mixture of the first fluoride and the second fluoride to a first temperature above at least the second melting temperature;
- casting the molten mixture of the first fluoride and the second fluoride in a mold;
- and
- cooling the molten mixture to form an article comprising a eutectic system having a super-lattice of the first fluoride and the second fluoride, wherein the eutectic system has a third melting temperature that is below the first melting temperature and the second melting temperature.
