Zircon Brick
zircon brick is made of stable and high pure zircon sand in which the zircon content is over 64 % , so zircon is as the main crystal phase ,it is an important firebrick in Zircon related refractory bricks. It has the advantages of high mechanical strength, high refractoriness under load, excellent thermal shock stability, good creep resistance and good corrosion resistance to glass liquid.

Special production method
Why does zircon brick have these great features? As the main raw material used is high pure zircon and the raw material will be special handled with Spray granulation process which will make the material more pure and easier to sintered, most of all, isostatic pressing technology is adopted to produce Zircon brick which is also an important factor to lead to its good features. Isostatic pressing technology, as a molding technology, has the following advantages:

1.Ensure high and uniform product density, as the equal pressure fluid medium pressure in all directions
2. Isostatic pressing forming process generally does not need to add lubricant in the powder, so it can not only reduce the pollution of the products, but also simplify the manufacturing process.
3. The products of isostatic pressing technology have excellent performance, short production cycle and wide application range.

Main application
Based on above mentioned method, zircon brick with excellent performance and features can mainly used in glass contact portion of alkali free or low-alkali glass melting furnace, especially some special region of glass tank, such as paving part and secondary layer of paving bottom, wall and bottom of forehearth, flowing spout and spinning portion and melter, back lining of forehearth, and also used in lining of other quality glass furnace and special glass furnace with high corrosion resistance, such as boron silicate glass, ceramic glass, low-alkali or other technical glass, and especially be used as superstructure bricks of flame space and bottom bricks of glass furnace.
