Overview of Mullite Crucible
Mullite crucibles are made from a high-performance ceramic material composed primarily of alumina (Al₂O₃) and silica (SiO₂). Known for their excellent thermal stability and mechanical strength, mullite crucibles are widely used in high-temperature applications such as melting metals, glass, and ceramics. They offer superior resistance to thermal shock and chemical attack, making them indispensable in both laboratory and industrial settings.
Features of Mullite Crucible
Thermal Shock Resistance: Exceptional ability to withstand rapid temperature changes without cracking.
High Mechanical Strength: Strong and durable, even at elevated temperatures.
Chemical Stability: Resistant to most chemicals, ensuring minimal contamination during processes.
Temperature Range: Can operate effectively at temperatures up to 1650°C.
Low Thermal Expansion: Minimal expansion or contraction with temperature changes, ensuring dimensional stability.
Non-Reactive: Does not react with the materials being processed, preserving sample purity.
Versatility: Suitable for a wide range of applications including metallurgy, glass manufacturing, and laboratory experiments.

Specifications of KERUI High-Temperature Refractory Block: Corundum-Mullite Bricks for Glass Melting Furnaces
Product Structure and Framework
KERUI Corundum-Mullite Bricks are made from high-purity synthetic corundum and mullite accumulations. These resources provide the blocks excellent resistance to high temperatures and chemical corrosion. The bricks have a thick structure with low porosity. This helps in reducing glass liquid penetration and prolongs service life in extreme furnace atmospheres.
Trick Efficiency Includes
These bricks work well at temperatures approximately 1700 ° C(3092 ° F). They show strong thermal shock resistance, which suggests they can deal with fast heating & cooling without cracking. Their high mechanical strength sustains structural stability under hefty tons inside glass melting heating systems. The bricks likewise stand up to disintegration from liquified glass and alkali vapors– common obstacles in glass manufacturing.
Physical and Chemical Features
Normal alumina (Al ₂ O SIX) web content is over 75%, making certain high refractoriness. Evident porosity stays listed below 18%, and bulk density is usually around 2.95 g/cm THREE. Cold crushing toughness exceeds 100 MPa. These numbers reflect regular top quality and reliability in real-world procedures.
Applications
KERUI Corundum-Mullite Bricks are excellent for essential components of glass melting heaters. Utilize them in superstructure locations like the crown, throat, and breast wall surfaces. They also do well in regenerator chambers and checkers where temperature level and chemical stress are high. Their stable performance assists preserve smooth glass manufacturing and lowers downtime for repair work.
Quality control
Every batch goes through strict testing before distribution. KERUI complies with global requirements to ensure uniform size, structure, and efficiency. Customized shapes and sizes are offered to match certain heater designs.

Applications of KERUI High-Temperature Refractory Block: Corundum-Mullite Bricks for Glass Melting Furnaces
Superior Performance in Extreme Warmth
KERUI corundum-mullite bricks are developed to handle the most difficult conditions inside glass melting heaters. These blocks remain strong even when temperatures exceed 1700 ° C. They resist thermal shock, chemical strike, and physical wear– vital difficulties in glass manufacturing.
Ideal for Vital Furnace Areas
These blocks function best partly of the furnace that encounter one of the most stress. That includes the superstructure, throat, and regenerator chambers. Their dense structure blocks liquified glass and vapors from permeating in. This aids keep the heating system lining intact longer and decreases upkeep downtime.
Long Life Span, Lower Expenses
Because they stand up so well under warmth and rust, KERUI corundum-mullite blocks last longer than lots of conventional refractories. A longer life indicates fewer substitutes. That reduces operating costs and increases heating system performance in time.
Consistent High Quality for Stable Manufacturing
Every brick fulfills stringent quality assurance. This makes certain consistent efficiency throughout large setups. Steady refractory efficiency indicates constant glass top quality and fewer production disruptions. Glassmakers can run their lines with more self-confidence and much less risk.
Trusted Across the Sector
Manufacturers around the world choose KERUI corundum-mullite bricks for soda-lime, borosilicate, and specialty glass heating systems. Their dependability has been shown in real-world operations. Customers report smoother runs, far better power usage, and more powerful heater honesty.

5 FAQs of KERUI High Temperature Refractory Brick Corundum – Mullite Bricks for Glass Melting Furnaces
Frequently Asked Questions About KERUI Corundum-Mullite Bricks
What are KERUI Corundum-Mullite Bricks made of?
These bricks are made from high-purity corundum and mullite. Both materials give the brick strong resistance to heat and wear. The mix creates a dense structure that holds up well in harsh furnace conditions.
Why use these bricks in glass melting furnaces?
Glass melting needs very high temperatures and long operating times. KERUI bricks stay stable under these conditions. They resist chemical attacks from molten glass and do not easily deform or crack. This helps keep the furnace running smoothly and safely.
How long do these bricks last?
Life span depends on furnace design, temperature, and operation method. In normal glass furnace use, KERUI Corundum-Mullite Bricks often last several years. Their low porosity and high strength reduce wear and extend service time.
Can these bricks handle thermal shock?
Yes. The balanced mix of corundum and mullite gives good thermal shock resistance. The bricks can go through heating and cooling cycles without breaking apart. This is important during furnace start-up, shutdown, or temperature changes.
Are KERUI bricks easy to install?
These bricks come in standard shapes and sizes. They fit well with common furnace designs. Skilled workers can lay them using regular refractory installation methods. Proper installation helps avoid gaps and ensures long-term performance.
