AZS zircon corundum bricks
Model Number: hongtai
Minimum Order Quantity:
Sintered AZS bricks are made of zircon and alumina as the main raw materials, and pre-synthesized materials are used as aggregates. Since the billet is an inert material, it is not effective to increase the molding pressure to increase the density of the product. The increase in the number of presses of large products may also lead to uneven cracking and density. It is necessary to adjust the critical particle size composition, add the composite binder and a small amount of TiO2. , MgO combustion aid and strengthening sintering to achieve the purpose of dense sintering.
The production principle is based on the solid phase reaction between ZrSiO4-Al2O3:
This reaction is an irreversible reaction and is also referred to as "in situ reaction". Due to the large volume effect in the reaction sintering process, resulting in deformation and cracking of the green body, only the pre-synthesized zirconium mullite aggregate, combined with sintered or fused corundum raw materials, can produce mullite, oblique zircon and corundum three-phase. Materials are superior to two-phase materials in terms of strength and thermal shock resistance. The microstructure of the sintered AZS brick is characterized by the uniform distribution of fine oblique zircon particles between the main crystalline phase mullite and corundum.
