Thermal Shock Resistant Zircon Mullite Brick MZ-20 MFZ-6 for Glass Furnace

Description of Thermal shock resistant Zircon mullite brick MZ-20 MFZ-6 for glass furnace

Sintered Zircon mullite brick is a special refractory material made by using industrial alumina and zircon concentrate as raw materials and introducing zirconium oxide into the mullite matrix through a reactive sintering process. Introducing zirconia into mullite bricks, and using the phase change toughening of zirconia can greatly improve the high-temperature mechanical properties of mullite materials. Zirconia can promote the sintering of mullite materials. The addition of ZrO2 can accelerate the densification and sintering process of ZTM materials due to the generation of low melting point substances and the formation of vacancies.

Difference between zircon mullite brick and sintered zirconium corundum brick

Chemical composition:
zircon mullite brick is mainly composed of zirconium oxide (ZrO2) and mullite (3Al2O3·2SiO2), and may also include other additives to adjust the properties. This combination provides good thermal shock resistance and a certain degree of erosion resistance.
Sintered zirconium corundum brick (sintered AZS brick) is mainly composed of zirconium oxide and corundum (α-Al2O3), and sometimes a small amount of silicate glass phase is added to promote sintering. This combination gives extremely high temperature resistance, erosion resistance and chemical stability.
Microstructure:
The microstructure of zircon mullite brick usually shows a network composed of zircon mullite crystals and zirconium oxide particles, which is conducive to thermal shock resistance.
The structure of sintered zirconium corundum bricks (sintered AZS bricks) tends to form a continuous network of corundum with zirconium oxide particles interspersed in it, which focuses more on providing high refractoriness and erosion resistance.
Performance differences:
1. Thermal shock resistance: zircon mullite bricks generally have better thermal shock resistance, which means that they are more resistant to thermal stress when the temperature changes rapidly and reduce the generation of cracks.
2. Erosion resistance: Sintered zirconium corundum bricks (sintered AZS bricks) perform better in chemical erosion resistance and high temperature resistance, especially in contact with alkaline or harsh chemical environments.
3. Mechanical strength: Sintered zirconium corundum bricks generally have higher mechanical strength, including compressive and flexural strength, suitable for heavier loads and mechanical wear.
Application areas:
zircon mullite bricks are more suitable for applications with higher requirements for thermal shock stability, such as some parts of glass kilns, specific furnace linings in ceramics and chemical industries.
Sintered zirconium corundum bricks (sintered AZS bricks) are more suitable for extremely high temperature and highly corrosive environments, such as the melting pool of advanced glass melting furnaces, the lining of certain metallurgical furnaces, etc.
In general, the brick you choose depends on the specific application requirements, such as operating temperature, degree of chemical attack, and whether it needs to experience frequent temperature changes.

Zircon mullite brick application: mainly used for paving the bottom of the glass melting part, paving the bottom of the cooling part, small furnace, regenerator lattice body, L-shaped hanging wall nose area, etc.
It is an indispensable key supporting material for a wide range of applications in large float glass kilns.
It is used in large glass kiln melting pool, picture tube kiln, regenerator partition wall brick, and chemical and metallurgical industry kilns that are corroded by solution.
Zirconia mullite refractory brick are widely used in non-metallic materials industry, petrochemical industry, steel smelting, military industry, electronics industry and other fields. For example: silicon steel heating furnace lining in metallurgical industry, thermal insulation lining of high-temperature equipment of hydrogen production furnace and gasifier in petroleum industry, thermal insulation lining of cemented carbide intermediate frequency furnace, etc
