Glassun Refractory

Glassun Fused Silica Refractories

Glassun refractories are manufactured from high-purity fused silica materials. There are four categories of Glassun refractories, including:

  • Glassun Series, shaped by slip casting
  • Glassun Castable monolithic refractories 
  • Glassun Cement


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
