Ceramic plate 68061-00001-1628

silicon carbidehigh-temperature

Product description
This setter plate is manufactured from reaction-bonded, high-purity silicon carbide (SiC) for stable, long-term load-bearing performance in high-temperature kilns. The plate features a smooth surface, tight dimensional tolerances and is suitable for processes requiring continuous exposure to elevated temperatures up to 1650°C (operational resistance ≥1300°C).

Key Features

• High-temperature capability: operational resistance ≥1300°C; maximum continuous use in air up to 1650°C
• Material: reaction-bonded high-purity silicon carbide (SiC)
• Precise dimensions: 400 × 350 × 5 mm with ±0.1 mm tolerances
• Low porosity and high density: apparent porosity ≤0.2% for improved load-bearing and reduced contamination
• Electrical and thermal performance: high resistivity and thermal conductivity 120–150 W/(m·K)

Applications

• Sintering of high-purity SiC components
• Ceramic and metal-powder industrial kiln processing
• High-temperature electronic materials processing
• Processing of refractory materials and other high-temperature load-bearing tasks
