What is a cordierite Support?
Cordierite Support refers to a bracket structure made of cordierite material. Cordierite is a magnesium aluminum silicate mineral with a low thermal expansion coefficient, good thermal shock resistance and fire resistance. These characteristics make cordierite an ideal material for manufacturing brackets used in high temperature environments. It is mainly used in refractory materials, electronic packaging materials, catalyst carriers, foam ceramics, printed circuit boards and low-temperature thermal radiation materials.

Characteristics and advantages of cordierite brackets
- Low thermal expansion coefficient: Cordierite has a low thermal expansion coefficient, which means that the size of the cordierite bracket changes less when the temperature changes, and it can maintain good dimensional stability.
- High strength and fire resistance: Although the density of the cordierite bracket is relatively low (2.53~2.78g/cm³), it has a high Mohs hardness (7.0~7.5) and a melting point of 1460℃, which allows it to maintain good mechanical strength and fire resistance in high temperature environments.
- Good seismic resistance: The seismic resistance of cordierite Supports is good, and they can resist vibration and impact to a certain extent, which is especially important for brackets used in environments such as industrial kilns.
- Suitable for high temperature environments: Due to these characteristics of cordierite, it is particularly suitable for manufacturing Supports that need to work in high temperature environments, such as ceramic kiln sheds, menurun, dll..

Manufacturing process of cordierite brackets
The manufacturing process of cordierite Supports mainly includes several key steps: selection of raw materials, molding, firing and post-processing.
First, high-purity cordierite ore must be strictly screened to ensure the quality of the final product. Then, the raw materials are processed into the required shape through pressing or mold forming technology.
Subsequently, the bracket is fired at high temperature to ensure its structural stability and high temperature resistance.
Finally, surface treatment and quality inspection are carried out to meet the use requirements and aesthetic effects.
The overall process requirements are rigorous to ensure the reliability and durability of cordierite brackets in various applications.

Application areas of cordierite Supports
| Area Aplikasi | Detailed description |
|---|---|
| Refractory Materials | Due to its low thermal expansion coefficient and good high-temperature thermal shock resistance, cordierite supports are often used to make tunnel kiln shed plates and support materials. They can significantly shorten the production cycle and can be used directly on flames. Lightweight cordierite materials have High efficiency and energy saving effect. |
| Ceramic catalyst carrier | Cordierite’s low expansion coefficient and good adsorption properties can be used to make catalyst carriers for automobile exhaust purification, helping the catalyst to better adsorb and disperse on the carrier and quickly reach the activation temperature. |
| Honeycomb ceramics | Cordierite honeycomb ceramics are mainly used in automobile combustion gas channels to absorb exhaust gas heat in the exhaust channel and transfer it to other heat recovery devices in the form of heat radiation. |
| Electronic packaging materials | Cordierite supports are also used in electronic packaging materials, especially where good thermal management and electrical insulation are required. |
| Foam ceramic | The porous structure and low thermal expansion coefficient of cordierite can be used to produce foam ceramics, which are suitable for chemical processing such as high-temperature flue gas filtration and catalytic combustion. |
