FTB16 Alumina Foam Block for Sealing 20mm OD Quartz Tubes in KSL-1100X-S3 Hybrid Furnace
The FTB16 alumina foam block is engineered to provide effective sealing and thermal insulation for quartz tubes with a 20 mm outer diameter, specifically designed for use with the KSL-1100X-S3 compact hybrid furnace. This component plays a critical role in maintaining the furnace’s thermal efficiency by minimizing heat loss around the quartz tube interface during high-temperature operations.
Manufactured from high-purity alumina (Al2O3), the foam block withstands maximum working temperatures up to 1700°C, making it suitable for demanding thermal processing environments. Its precise dimensions—16 mm in diameter and 51 mm in length—ensure a snug fit for sealing 20 mm OD quartz tubes, contributing to stable furnace performance and process reliability.
Key Features
- High-purity alumina material for excellent thermal resistance and durability.
- Designed specifically to seal 20 mm outer diameter quartz tubes.
- Compatible with MTI’s KSL-1100X-S3 hybrid furnace featuring three tubes and flanges.
- Maximum operating temperature of 1700°C for high-temperature applications.
- Dimensions optimized for a secure fit: 16 mm diameter, 51 mm length.
- Surface cracks may develop over time but do not impair functionality; repairable with alumina coating.
