Cordierite Mullite-Pressed Pillar/Props has excellent high-temperature stability and structural stability, as well as a wide range of applications. Whether it is used as a material for the production of daily-use porcelain or as a support for refractory bricks, it demonstrates excellent performance.
Cordierite Mullite Pressed Pillar/Props is a ceramic material product that combines the advantages of both cordierite and mullite. Pressed by a precise process, they are not only structurally stable but also show excellent heat resistance in extreme high temperature environments.Fireramo, as the manufacturer, uses a unique formula to ensure consistent quality and meet the needs of various high-temperature applications.

High Temperature Stability: The product can remain stable in environments up to 1600°C or more, ensuring that it will not be deformed or fail over a long period of time.
Structural stability: Unique material ratios and pressing processes make the internal structure of the product compact and not easily affected by the external environment.
Dimensional accuracy: Strict control of the production process ensures the dimensional stability of the product to meet the needs of high-precision applications.
High strength: the product has excellent cold compression strength and load refractoriness and can withstand large mechanical and thermal stresses.
Cordierite Mullite-Pressed Pillar/Props are widely used in various high-temperature applications, such as the manufacture of daily-use porcelain, craft porcelain, sanitary ware, and as a support for refractory bricks. Its excellent high-temperature performance and stability make it an ideal choice for high-temperature industrial fields.
