Corundum-Mullite Setter Plate

Corundum-Mullite Setter Plate — Product Specification & Description

1. Product Overview

The Corundum-Mullite Setter Plate is a high-purity, ultra-high-temperature refractory tray engineered for demanding industrial thermal processes. Formulated by combining hard, wear-resistant corundum ($alphatext{-}Al_2O_3$) with high-purity mullite ($3Al_2O_3cdot2SiO_2$), this setter plate offers exceptional high-temperature load-bearing capacity, resistance to structural deformation, and superior chemical stability. It is specifically designed for high-stress sintering environments where standard refractories fail under heat and load.

2. Key Features & Advantages

• High Working Temperature: Continuous operation capability up to 1600°C – 1700°C (2912°F – 3092°F) with low thermal creep.

• Superior Load-Bearing Strength: Outstanding flexural and hot-bending strength under heavy weight loads at elevated temperatures.

• Excellent Chemical & Corrosion Resistance: Resists reaction, slag erosion, and fluxing agents in oxidizing, reducing, or vacuum atmospheres.

• Low Thermal Contamination: High chemical purity prevents cross-contamination and staining of high-value electronic and structural ceramics.

• Thermal Stability: Lower thermal expansion and high hot modulus of rupture prevent sagging, bowing, and physical distortion over repeated high-heat cycles.
