2. High-Temperature Furnaces

Kiln furniture (saggers, setters) for ceramic/powder metallurgy processing

3. Glass Manufacturing

Thermocouple protection tubes in glass melting tanks

4. Semiconductor Equipment

Wafer processing components requiring low thermal expansion

5. Thermal Processing

Heat exchanger plates for regenerative burners

Why Choose Cordierite Blocks?

✔ Unmatched Thermal Stability – Withstand 100+ rapid thermal cycles (1,000°C⇄RT)

✔ Custom Machining – Laser-cut, drilled, or CNC-machined to your drawings

✔ Chemical Resistance – Excellent acid/alkali resistance (except HF)

✔ Cost-Effective – Longer service life than mullite or alumina alternatives

Technical Parameters

Production process

1. Grind and crush the raw materials to be slurry or powder

2. se-different method to making the slurry or powder into semi-finished products

3. Put the semi-finished products into the kiln for dewaxing and sintering;

4. After forming and sintering, Ceramic Sleeves products can also be processed by subsequent CNC precision machining according to the drawing requirements. Then Q/C test.

5. Finally package Ceramic Sleeves by bubble paper or cartons and place it on tray for delivery
