Abstract
An ionically conductive glass (or glassy) monolithic preform having a certain shape, size, and dimension may be made from a monolithic precursor material (e.g., an ingot or boule of ion conductive glass), generally of a different shape and size.
Claims10
A method of making an ionically conductive glass preform, the method comprising:
- a. providing an inorganic ion conductive glass monolith as a precursor material, the glass precursor monolith having a precursor shape, size, dimension, glass transition temperature (Tg), and glass melting temperature (Tm);
- b. providing a collapsible hollow structure having a wall with an inner and outer surface;
- c. disposing the glass precursor monolith inside the collapsible hollow structure;
- and
- d. pressing and heating the glass precursor monolith while it is inside the collapsible hollow structure, wherein the temperature of the glass precursor monolith during pressing is at or above the precursor Tg, wherein the pressing and heating operation uniformly collapses the hollow structure and thereby transforms the glass precursor monolith into a monolithic glass preform having a preform shape and dimension different than that of the glass precursor monolith;
- wherein an inner liner material is disposed inside the collapsible hollow structure and thereby serves as an interlayer between the glass precursor monolith and the inner wall surface of the collapsible hollow structure.
