Superior Thermal Stability and Chemical Resistance

Sillimanite Bricks offer unparalleled stability at high temperatures and under severe conditions. With a melting point exceeding 1800C and remarkable resistance to both chemical attack and slag or glass corrosion, they are perfectly suited for industrial furnace linings, incinerators, and glass manufacturing units. Their low water absorption (<1%) and low thermal expansion provide dimensional reliability and enhanced lifespan.

Precision Engineering and Custom Solutions

Manufactured through high-pressure firing processes, these bricks feature a smooth finish, consistent density (2.55 g/cm), and can be supplied in standard rectangular dimensions or tailored shapes to meet specific project needs. Their excellent mechanical strength, low porosity, and superior surface hardness (7585%) ensure dependable performance even in the most demanding industrial environments.

FAQs of Sillimanite Bricks:

Q: How are Sillimanite Bricks manufactured to ensure high mechanical strength?

A: Sillimanite Bricks are produced through a high-pressure shaping and firing process. This method results in a dense, robust structure with a cold crushing strength of at least 60 MPa, making the bricks highly resilient to mechanical and thermal pressures.

Q: What are the main benefits of using Sillimanite Bricks in industrial furnaces?

A: The main advantages include superior resistance to high temperatures (service temperature up to 1700C), excellent thermal shock resistance, minimal thermal expansion (0.4% at 1500C), stability under chemical and corrosive conditions, and a long operational life, making them ideal for furnace linings and other extreme environments.

Q: When should I choose Sillimanite Bricks over other types of refractories?

A: Sillimanite Bricks are optimal when applications require high refractoriness under load (>1700C), outstanding resistance to chemical corrosion and thermal shock, and low porosity. They are particularly recommended for kiln linings, glass furnaces, and incinerators subject to severe operating conditions.

Q: Where can Sillimanite Bricks be used in industrial operations?

A: These bricks are widely applied in industrial sectors such as glass manufacturing, foundries, ceramic kilns, metal processing, and waste incineration, wherever reliable refractory linings are essential to withstand harsh temperatures and corrosive atmospheres.

Q: What is the typical process for packing and delivering Sillimanite Bricks?

A: Sillimanite Bricks are securely packed on wooden pallets and shrink-wrapped to prevent transit damage and moisture absorption, ensuring they maintain their quality and structural integrity upon delivery to national or international clients.

Q: How does the chemical composition of Sillimanite Bricks contribute to their performance?

A: The high purity of Al2SiO5, with minimal Fe2O3 and TiO2 content, enhances thermal and chemical stability, ensuring the bricks maintain excellent integrity and resist slag, glass, and corrosive agents in high-temperature processes.
