Description

Zircon bricks are produced using high-quality raw materials, composite ultra-fine powder, and special additives, which undergo high-pressure forming and high-temperature sintering. They offer several advantages, including strong resistance against glass erosion and penetration, excellent thermal shock stability, and high-temperature creep resistance. These bricks find primary application in the molten pool and superstructure of glass furnaces.

Properties of Dense Zircon Bricks:

  1. Good thermal shock resistance.
  2. High-temperature resistance.
  3. Resistance to glass erosion.

Applications of Dense Zircon Bricks:

  1. Zircon bricks are mainly used in alkali-free glass and borosilicate glass pool kilns, including the bottom, upper space brick, hook brick, gap brick, runner brick, thermocouple brick, and observation hole brick.
  2. Zirconium-containing refractories find widespread use in the bottom of glass kiln pools, paving brick, and kiln superstructures, such as arch bricks, corner bricks, chest wall bricks, transition bricks, temperature bricks, and observation hole bricks.
  3. Zircon fire bricks are utilized in the lining of the molten pool of glass kilns for melting glass fibers.
