Product Description
Cordierite mullite board is fired with mullite as aggregate and cordierite as base material. Since cordierite has a (SiO2)n ring-shaped
structure, there are large voids in this structure, so it has the characteristics of small thermal expansion coefficient, while mullite has
a large thermal expansion coefficient, resulting in a mismatch between the expansion coefficients of the two materials, making the
two materials.
The formation of fine cracks at the phase interface can effectively reduce the thermal stress caused by temperature changes, effectively
avoid the spread of catastrophic cracks, and greatly improve the thermal stability of cordierite-mullite refractories; at the same time,
because mullite The crystal has high refractoriness (melting point is 1810°C) and high mechanical strength (bending strength at room
temperature is 49MPa), so using mullite as aggregate can effectively improve the high temperature strength of the shed.
Features of Cordierite mullite board:
1. High temperature resistance: It can withstand extremely high temperatures, typically up to 1,400°C (2,552°F) They exhibit excellent
thermal stability, maintaining their structural integrity even under rapid temperature changes.
2. Low thermal expansion: These boards have a low coefficient of thermal expansion, meaning they expand and contract minimally when
exposed to temperature variations. This property helps to prevent cracking and deformation of the kiln furniture during thermal cycling.
3. Chemical inertness: Cordierite-mullite slabs are chemically inert, meaning they do not react with most chemicals or molten metals
encountered in high-temperature processes.
Application of Cordierite mullite board:
1. Kiln furniture: Cordierite-mullite boards are widely used as kiln furniture in industries such as ceramics, glass, and metallurgy. They
provide a stable and heat-resistant platform for supporting ceramic ware, glass sheets, and metal parts during firing processes.
2. Heat treatment furnaces: Cordierite-mullite slabs are used as shelves or supports in heat treatment furnaces where materials need
to be exposed to high temperatures for processes such as annealing, sintering, or tempering.
3. Industrial kilns: Cordierite-mullite slabs are utilized in various industrial kilns, including tunnel kilns, roller kilns, and shuttle kilns.
