Sintered zircon with 66% zirconia

Description

Zirconium silicate. Very high resistance to vapours corrosion. Available in standard brick format.

Typical application

ZPR is used a large range of application:

  • bottom sub-paving,
  • superstructure as buffer course between silica and fused cast materials,
  • reinforcement and textile fiber glass furnaces superstructure.

If mortar is required, use ERZIR MORTAR.

For more complex and larger shapes refer to CZCT.
