CZCT
Sintered zircon with 63% zirconia
Zirconium silicate. Very high resistance to vapours corrosion and good thermal shock resistance. Available in complex and large shapes.
Typical application
CZCT is used in superstructure areas for special shapes application such as burner blocks, peep-holes, thermocouple blocks.
For standard brick format refer to ZPR.
