Product Description:
Cordierite Mullite kiln shelves is a high-performance refractory
material composed of cordierite and mullite, which is widely used
in high-temperature industrial environments. The following is a
detailed introduction to it:
Composition & Characteristics: Cordierite: Has a low thermal
expansion coefficient and excellent thermal shock stability, but
relatively low mechanical strength. Mullite: Provides high
mechanical strength and high temperature resistance, but its
thermal expansion coefficient is relatively high. This composite
material combines the advantages of both to form a material with
good thermal shock stability, high mechanical strength and strong
refractory resistance, suitable for environments with high
temperatures and chemical corrosion.
Features:
● High Temperature Resistance: Cordierite mullite has a refractory
temperature of up to 900 to 1280℃, suitable for a variety of
high-temperature environments. ● Thermal Shock Stability: Combining
the characteristics of cordierite and mullite, this material has
excellent thermal shock resistance and can effectively resist the
thermal stress caused by rapid temperature changes, thereby
extending the service life12. ● Lightweight and Energy-saving: The
material is relatively light and absorbs less heat. It can be made
into hollow or thin-walled kiln furniture, which helps save fuel
and reduce the burden on equipment1. ● Chemical Stability: The
combination of cordierite and mullite provides good chemical
inertness, which can prevent adverse reactions with fired products
and ensure product quality. ● High Mechanical Strength: The mullite
part gives the material high mechanical strength, making it perform
well under heavy loads and suitable for various industrial
applications. ● Wide Application: Cordierite mullite board is not
only used in kiln furniture in the ceramic industry, but also in
electronic packaging materials and solar thermal power generation
materials, showing its versatility.

plates, are durable and heat-resistant shelves used for kiln
firing. They come in rectangular, round, and square shapes and can
be customized in size. They have a smooth edge and are available in
white or yellow color. With a high thermal expansion coefficient
and thermal shock resistance of 200℃, these cordierite kiln shelves
are a reliable choice for kiln firing applications. |
Applications:
Main Application
1 Ceramic industry: Used in the firing process of daily-use
ceramics, sanitary ceramics, building ceramics and industrial
ceramics, as kiln tools and kiln body structural materials,
ensuring stability and fire resistance at high temperatures.
2 Electronic Ceramics: Used in the firing of electronic ceramics,
especially products such as ferrites and resistors, the kiln tools
are required to have good chemical inertness and thermal shock
stability.
3 Lithium Battery Materials: Used in the firing of lithium battery
positive electrode materials, cordierite mullite provides the
necessary strength and alkali corrosion resistance in this process
to improve product quality.
4 Combustion Board: As the material of the combustion board,
combining the characteristics of cordierite and mullite It improves
mechanical strength and thermal stability and prolongs service
life.
5 Electronic Equipment: Applied in electric heating electrical
equipment, such as hot air guns and hair dryers, as insulation
materials and the skeleton of heating elements.
6 Solar Thermal Power Generation: In solar thermal power generation
systems, it is used as a high-temperature pipeline material,
requiring good high-temperature stability and thermal shock
resistance.
7 Building Materials: Due to its excellent fire resistance, it can
also be used as refractory bricks or other structural materials in
buildings to improve the safety and durability of buildings.
