ceramic socket cup ceramic plug C520 cordierite shenxing ceramic

Cordierite ceramic plug is a custom‑shaped refractory component made of cordierite (magnesium aluminosilicate, chemical formula: 2MgO·2Al₂O₃·5SiO₂), one typical form of cordierite insulating / heat‑resistant ceramic parts.

This ceramic plug is specially designed for high‑temperature working environments with frequent heating‑cooling cycles. Thanks to its ultra‑low coefficient of thermal expansion, it provides outstanding thermal‑shock resistance, which prevents cracking under rapid temperature fluctuation, the most important advantage compared with alumina or steatite ceramic plugs.

설명

Cordierite Ceramic Plug

Made of magnesium aluminosilicate, cordierite ceramic plugs offer outstanding thermal‑shock resistance due to low CTE. Good electrical insulation and high‑temperature dimensional stability up to 1300°C. Custom geometries are available for burners, thermocouple assemblies and kiln supporting applications.

Application

Typical Applications of the ceramic plug socket cups

• Insulating plug / stopper for burner, gas ignition assembly

• Thermocouple insulating plug and temperature‑probe fixture

• Locating plug & spacer for kiln furniture, furnace support

• Stud welding ceramic ferrule / plug

• Heat‑resistant blocking component for heating equipment

Advantages

Key Features & Advantages of the cordierite ceramic plug socket cups

1 Excellent thermal shock resistance

Low CTE (typically 1–3 ×10⁻⁶ /°C). It can survive repeated sharp temperature changes without fracture.

2. Good electrical insulation

High volume resistivity and stable dielectric property, suitable for insulation and isolation in heating assemblies, sensor fixtures or burner systems.

3. High‑temperature dimensional stability

Max continuous service temperature up to 1100–1300°C. Minimal deformation under long‑term heat load.

4. Cost‑effective refractory solution

Lower material cost than high‑purity alumina when thermal cycling resistance is the primary requirement.

5. Customizable geometry

We can produce various plug shapes, inner holes, steps, grooves by dry pressing, extrusion or isostatic pressing according to customer drawings.
