The invention relates to new glass formulations with alumina contents greater than 35 mol % and methods for making these glasses. The glass may be a porous glass or a dense glass.

Alumina-rich glasses and methods for making the same

The present invention is drawn to a lithia alumina silica material that exhibits a low CTE over a broad temperature range and a method of making the same. The low CTE of the material allows for a decrease in microcracking within the material.

Near zero coefficient of thermal expansion of beta-eucryptite without microcracking

The invention provides composite materials comprising eucryptite particles distributed in a matrix material other than eucryptite. The matrix material may be a ceramic material such as an oxide ceramic. In an embodiment, the eucryptite particles are transformed from the &#x3b2;-phase to the &#x3b5;-phase during fabrication of the composite. This phase transformation can enable a eucryptite-based transformation toughening mechanism.
