CoolingCustom-Shaped Reaction-Bonded Silicon Carbide (RBSiC/SiSiC) Sagger: High-Performance Refractory Solutions for Extreme Industrial Environments

Description:

Reaction-Bonded Silicon Carbide (RBSC) Sagger is a high-performance refractory container fabricated from high-purity silicon carbide (SiC) powder via reaction-bonded sintering technology. This process incorporates silicon (Si) as a binder, forming a dense microstructure under high temperatures while controlling shrinkage (≤3%) to ensure high dimensional accuracy and minimal deformation. The sagger typically features a square or circular shape with a smooth surface and can be customized into specialized geometries (e.g., U-shaped, arched, or perforated designs) to meet extreme industrial requirements such as high temperatures, strong corrosion, and rapid thermal cycling.

The physical properties of reaction sintered silicon carbide ceramics products:

Key Features:

1. Exceptional High-Temperature Resistance
   • Operates continuously at temperatures up to 1,380°C, surpassing conventional graphite (≤1,200°C) and alumina-mullite (≤1,300°C) alternatives.
   • Maintains structural integrity without softening, deformation, or cracking under prolonged heat exposure.
2. Superior Thermal Shock Resistance
   • Low coefficient of thermal expansion (1/6–1/7 of graphite), enabling resistance to rapid heating/cooling cycles (e.g., quenching from 1,300°C to room temperature) without spalling or cracking.
3. Outstanding Corrosion Resistance
   • Highly resistant to strong acids (e.g., sulfuric, nitric, hydrochloric acid) and alkalis (e.g., sodium hydroxide), extending service life 3–5× longer than graphite crucibles and 8–10× longer than alumina-mullite saggars.
4. High Thermal Conductivity & Uniform Heat Distribution
   • Thermal conductivity of 45 W/m·K ensures rapid heat transfer, reducing energy consumption by >20% while promoting uniform product sintering and improving yield rates.
5. Lightweight yet Robust
   • High bulk density and strength combined with lower weight than traditional refractories, facilitating easy handling and integration into automated production lines.
6. Customizable Design Flexibility
   • Supports tailored shapes (e.g., slots, grooves, or porous structures) for specialized processes. Surface treatments (e.g., polishing, coatings) enhance anti-sticking or corrosion resistance.
