Key Features and Benefits
Superior Thermal Shock Resistance
The unique corundum-mullite interface creates tiny microcracks that absorb stress during fast heating and cooling. This microcrack toughening means less cracking and longer life under tough kiln cycles.
High Load-Bearing Strength at Elevated Temperatures
Our composite plates hold strong and stay stable up to 1700°C, making them perfect for heavy-duty ferrite sintering and other demanding applications in electronics and metallurgy.
Chemical Inertness
The material won’t react with glazes, powders, or any firing atmosphere. This ensures your parts stay clean, contamination-free, and consistent batch after batch.
Energy Efficiency
Thanks to low thermal conductivity, Gotrays Corundum-Mullite Composite Plates speed up firing times and reduce kiln energy use by 15–20%, helping you save on costly fuel or electricity.
Durability and Cost Savings
These plates last over 20 times longer than traditional cordierite kiln furniture, cutting down on frequent replacements and downtime—saving you serious time and money.
Visual Comparison
Our plates deliver about 25% better shock resistance compared to pure mullite products, verified through real testing and shown in easy-to-read infographics for quick reference.

Gotrays Corundum Mullite Composite Plates Engineered for High Temp Reliability
If your kiln downtime is costing you, cracked plates might be the cause. Gotrays Corundum Mullite Composite Plates are built to handle extreme heat without breaking down, keeping your production running smooth. Designed for maximum durability, these plates combine corundum’s hardness with mullite’s thermal stability to outperform traditional kiln furniture.
Perfect for electronics fabs and metalworks across the US and EU, our composite plates deliver up to 1700°C resistance and resist thermal shock better than pure mullite or alumina options. When you need reliable, long-lasting setter plates or push boards for sintering and firing, Gotrays has you covered.
What Makes Corundum Mullite Composites Superior
When you’re dealing with extreme kiln temps, the material inside really matters. Gotrays Corundum Mullite Composite Plates combine the best of both worlds — the rock-solid hardness of corundum and the thermal stability of mullite.
-
Corundum’s Hardness
Corundum is known for its high alumina content (70-80%), giving it excellent wear resistance and durability. This tough crystal structure makes the plate highly resistant to abrasion and mechanical wear, perfect for heavy-duty sintering or pushing.
-
Mullite’s Thermal Stability
Mullite adds thermal shock resistance and stability, thanks to its unique crystal makeup. It handles rapid heating and cooling better than pure alumina, preventing cracks and warping during quick temperature changes.
-
Toughening through Microcracks
One of the key benefits of the composite is microcrack toughening. The interface between corundum and mullite creates tiny microcracks that absorb stress instead of letting it spread. This means improved shock absorption and longer life under rapid thermal cycles.
Here’s a quick visual comparison showing why Gotrays Corundum Mullite plates outlast standard alumina or cordierite kiln furniture:
| Property | Corundum Mullite Composite | Pure Alumina | Cordierite |
|---|---|---|---|
| Max Temp (°C) | Up to 1700 | 1600 | ~1300 |
| Thermal Shock Cycles | >20 | 10-15 | 5-8 |
| Flexural Strength (MPa) | 20-30 | 15-20 | 10-15 |
| Resistance to Wear | Excellent | Good | Moderate |
Quick Calc for Your Kiln
Match your kiln’s max temp to Gotrays plate specs to get the best fit:
- Up to 1700°C → Gotrays Corundum Mullite is ideal
- Below 1500°C and lower thermal shocks → Mullite or alumina options could work
- Frequent rapid cycles → Choose Corundum Mullite for superior shock resistance
With these plates, US ceramics and electronics manufacturers get reliable, long-lasting kiln furniture that cuts downtime and boosts productivity.
