FUSED SILICA

While fused silica refractories do not have the high operating temperatures as alumina refractories, it does provide superior thermal shock resistance in both kiln furniture and molten metal applications. In addition to its high thermal shock resistance, fused silica refractories also have an extremely low coefficient of thermal expansion, making it an excellent choice in applications that require dimensional stability.

TYPICAL PROPERTIES OF FUSED SILICA ARE:

• Superior thermal shock resistance

• Excellent hot strength

• Low coefficient of thermal expansion

• Minimal preheating required

• Can be used without a steel backing shell

TYPICAL APPLICATIONS FOR FUSED SILICA ARE:

• Kiln furniture for powder metal and ceramic processing

  • saggers

  • pusher tiles

  • boats

  • setter plates

• Crucibles and ladles for melting ferrous alloys

• Kiln components

• Metering pins
