Abstract
An exemplary embodiment of the present disclosure provides a method for manufacturing a transparent ceramic material. The method comprises providing a compact comprising a metal oxide and, during sintering, exposing the compact to a vapor comprising one of or both fluorine ions and lithium ions to form a transparent ceramic material comprising at least 90% of a theoretical transparency.
Claims18
A method comprising:
- thermally vaporizing a material comprising lithium and fluorine to produce a vapor;
- and
- pressureless sintering a compact comprising a metal oxide while exposing the compact to the vapor to form a transparent ceramic material having at least 90% of a theoretical transparency;
- wherein thermally vaporizing the material is proximate the compact.
