Product Description
Specifications
1.better thermal shock resistance2.more suitable for regenerator of glass furnace
Zircon Mullite Brick
Advantage of products: Zirconia mullite bricks have better thermal shock resistance compared with pure mullite bricks. The added zirconia can improve the mullite bricks quality and becomes more suitable for regenerator of glass furnace.
