Glassun Refractory

GLASSUN Fused Silica Refractories™

GLASSUN™ series refractories are manufactured from high-purity fused silica materials and shaped by slip casting. GLASSUN refractories can be fabricated into various sizes including large monolithic sizing, and can be configured into various complex shapes. Each series of Glassun provides superior performance due to the following properties:

  • High thermal shock resistance due to a low thermal expansion rate
  • Low thermal conductivity
  • Extraordinary corrosion resistance to chemicals and molten metals
