Dense zirconia Bricks adopt Australian zirconia recycled aggregates, zircon powder, compound ultrafine powder and special admixture , made by high-pressure forming, high temperature sintering.
Application of Dense Zirconia Bricks
Dense zirconia bricks are mainly used in the bottom and upper structure of the glass kiln.
Characteristics of Dense Zirconia Bricks
- Strong anti-glass corrosion
- Strong penetration resistance
- Thermal shock resistance
- High compressive strength
- High RUL
