Title: High thermal expansion glass composites and uses thereof

Abstract

The present invention relates to glass composites, including filled glass composites and uses thereof. In particular examples, the composites provide improved thermal expansion characteristics. Also described are methods of forming such composites, such as by adding a particle filler to a glass mixture.
