Pyrotek Dense Fused Silica Pre-Cast Shapes
Categories: Ceramic; Oxide; Silicon Oxide

Material Notes: Pyrocast Dense Fused Silica is an economical product for shapes demanding thermal shock resistance at temperatures. Pyrocast DFS stands up to repeated use in molten metal casting in aluminum, copper, zinc, brass, steel, glass, and aerospace applications. It is durable and resists breakage during handling and cleaning. Components made from Pyrocast Dense Fused Silica resist cracking due to the material's low thermal expansion.

Applications

  • Spouts
  • Control pins
  • Mounting seats (inserts)
  • Pre-cast trough tiles
  • Thimbles
  • Wear plates
  • Trough dams

Advantages

  • Resistant to thermal shock
  • Superior strength
  • Low thermal expansion
  • Economically priced
  • Resistant to surface corrosion
  • Able to rapidly cycle
  • Computer controlled firing
  • Superior material consistency
