Technical Specifications of Sillimanite Ceramic Rod

Our Gotrays Sillimanite Ceramic Rods are made from pure sillimanite (Al2SiO5), which converts into strong mullite when fired. This process ensures high durability in extreme heat.

• Alumina Content: Ranges from 52% to 90% Al2O3, with custom grades available to suit your needs.
• Dimensions: Outer diameter from 10mm up to 250mm and lengths between 50mm and 2000mm. All rods are precision machined to a tolerance of ±0.1mm for a perfect fit.
• Density: Between 2.5 and 3.2 g/cm³, providing excellent structural strength.
• Thermal Conductivity: Falls between 2 and 4 W/mK, ensuring efficient heat distribution during operation.
• Compressive Strength: Over 1000 MPa, making these rods ideal for supporting heavy loads inside kilns and furnaces.
• Porosity: Less than 1%, creating impervious rods that are leak-proof and suitable for gas-tight applications.
• Certifications: Manufactured under strict ISO 9001 standards and RoHS compliant, guaranteeing quality and safety.

These specs make Gotrays Sillimanite Ceramic Rods reliable for industrial ceramic insulators, kiln heating element supports, and other high-temperature refractory needs.

Features and Benefits

Why Choose Gotrays Sillimanite Ceramic Rods

Gotrays Sillimanite Ceramic Rods stand out for their thermal shock resistance. They handle quick heating and cooling cycles without cracking, making them perfect for tough jobs like induction forging.

We use only high purity sillimanite with less than 0.5% impurities like sodium and calcium. This means our rods form strong needle mullite, giving you about 20% stronger interlocking for longer-lasting performance.

These rods are built for durability. They resist attacks from molten metals, acids, and oxidation, so they hold up well in tough environments like blast furnaces or glass tanks.

Plus, we offer custom fabrication. Need specific outer diameters, lengths, threading, or coatings? We can tailor our rods to fit right into your setup with no hassle.
