Fused Silica

Fused silica is high purity quartz sand that has been melted to form glass.

High volume stability, low volumetric expansion and high purity make fused silica a very useful and versatile material for refractory applications, whether in aluminum launders or other highly cyclical applications.

Our fused silica, Teco-Sil® has an extremely low thermal expansion coefficient, consistent chemistry and carefully controlled particle size distribution. Teco-Sil products are specially engineered grains and powders designed for use in foundry, refractory, investment casting and other special applications.

Teco-Sil is produced at Imerys Greeneville fusion plant in Tennessee, USA.
