High temperature resistance Corundum-mullite ceramic setter trays

Ceramic setter trays play a pivotal role in ceramic kilns, ensuring the safe transport and firing of ceramic green bodies. With the sintering temperature for materials like MLCC (Multilayer Ceramic Capacitors) often exceeding 1200°C, the demand for high-specification ceramic setter trays is on the rise. Addressing this need, we introduce our top-tier corundum-mullite ceramic setter trays, designed for enhanced performance and longevity. Dive into the features, benefits, and applications of these state-of-the-art trays.

  • Color: White
  • Density: 2.85-3.0g/cm3
  • Apparent porosity: 18%
  • Room temperature flexural strength: 90MPA
  • High temperature flexural strength: 10MPA
  • Al2O3: 86%
  • SiO2: 13%

Product Description


Made from high-purity corundum and mullite, our ceramic setter trays undergo rigorous testing to ensure unmatched quality. The synergy of corundum (Al2O3) and mullite (3Al2O3·2SiO2) offers a plethora of benefits for high-temperature ceramic processing. While corundum boasts unparalleled wear and thermal shock resistance, mullite provides minimal thermal expansion and superior creep resistance. The result? Trays that stand the test of time, temperature, and toughness.


Product Feature


Beyond traditional kiln furniture materials, corundum-mullite kiln trays offer:

1. Exceptional Temperature Resistance: Capable of enduring up to 1700°C (3092°F), ideal for advanced ceramics and electronic components.

2. Thermal Shock Stability: Resilient against rapid temperature shifts, minimizing risks of cracks and deformations.

3. Consistent Dimensions: A low expansion coefficient ensures the tray remains intact despite temperature variations.

4. Robust Mechanical Strength: The fusion of corundum and mullite ensures the trays can bear heavy loads without warping.

5. Enhanced Corrosion Resistance: The trays’ chemical stability ensures longevity even in corrosive settings.


Product Application


Corundum-mullite ceramic setter trays are revolutionizing ceramic kilns. Their unique properties optimize heat transfer, reduce energy consumption, and ensure uniformity in fired products. These trays are perfect for:

Advanced Ceramics: Ideal for firing materials like zirconia, alumina, and silicon nitride.

Electronic Components: Precision and stability make them suitable for producing top-quality electronic components.

Glass Processing: Their thermal shock resistance is a boon for applications like annealing and tempering.
