■ Introduction:
The cordierite mullite crucible is a type of ceramic crucible that is used for high-temperature applications such as melting metals, alloys, and other materials. The Cordierite mullite ceramic sagger is made from a combination of cordierite and mullite, which are both highly refractory materials that can withstand extreme temperatures without degrading or cracking.
The cordierite is made up of magnesium, aluminum, and silicon which has excellent thermal shock resistance and can withstand temperatures up to 1,200°C. The Mullite is a synthetic material that is made from alumina and silica, which has a high melting point of around 1,850°C and is highly resistant to thermal shock.
The cordierite mullite sagger commonly used in industries such as metallurgy, foundry, and glass manufacturing. They are available in a range of sizes and shapes to suit different applications and can be customized to meet specific requirements.

■ Advantages:
1. The refractory cordierite mullite sagger is highly resistant to thermal shock,
2. The cordierite mullite for kiln funiture is high chemical corrosion, and mechanical wear.
3. The refractory cordierite mullite tray is good for fast firing to the end products.
4. The temperature difference is small between the cordierite mullite sagger and the fired products.
