ZPR
Sintered zircon with 66% zirconia
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.
