Why Choose Cordierite Ceramics to Meet Your Industrial Needs

Brief introduction

Cordierite ceramics (2MgO·2Al₂O₃·5SiO₂) have become an irreplaceable material in high-temperature thermal cycling environments due to their ultra-low thermal expansion coefficient and excellent thermal shock resistance. From automobile exhaust treatment to 5G communication, from high-temperature filtration to precision electronics, cordierite ceramics are providing unique solutions for various industries. 

Here are the top ten key advantages of choosing cordierite ceramics:

1. Ultra low thermal expansion coefficient

The coefficient of thermal expansion is only 1.5-2.5 × 10 ⁻⁶/K (25-800 ° C), close to zero expansion, making it an ideal substrate material for precision optical devices and satellite antennas.

2. Unparalleled thermal shock resistance

Capable of withstanding rapid cooling and heating with Δ T>1000 ° C, it performs excellently in thermal cycling applications such as automotive catalytic converters and industrial kilns.

3. Lightweight porous structure

The density is only 2.0-2.6g/cm ³, which is 30% lighter than alumina. The honeycomb structure can achieve a controllable porosity of 20-50%.

4. Excellent thermal insulation performance

Thermal conductivity of 1-3W/(m · K), combined with porous structure, is the best choice for high-temperature furnace lining and thermal barrier coating.

5. High frequency dielectric properties

Dielectric constant 4-5 (1MHz), dielectric loss<0.001, perfect for 5G base station antennas and millimeter wave devices.

6. Environmental friendliness

The raw materials are abundant and non-toxic, and the energy consumption during the production process is 60% lower than that of silicon carbide, which meets the requirements of green manufacturing.

7. Chemical stability

Resistant to weak acid and weak alkali corrosion (except HF), it is a high-quality material for chemical filters and bioreactors.

8. Workability

It can perform secondary processing such as precision drilling and laser cutting, achieving a dimensional accuracy of ± 0.05mm.

9. Cost effectiveness

The price is only one-third of that of silicon carbide ceramics, which has significant advantages in large-scale applications such as diesel particulate filters (DPF).

10. Multi functional composite

Can be compounded with metals and polymers to create a new type of composite material that combines low expansion and high strength.
