Custom-Shaped Reaction-Bonded Silicon Carbide (RBSiC/SiSiC) Saggers: The Ultimate Refractory Solution for Extreme Industrial Environments

Product Description

Discover our custom-shaped Reaction-Bonded Silicon Carbide (RBSiC/SiSiC) saggers. Engineered for extreme heat (1380°C), thermal shock, and corrosion. Outperforms graphite & alumina with longer life, lower energy costs, and tailored designs for your process.

In industries where temperatures soar, corrosive atmospheres are the norm, and thermal cycles are relentless, conventional refractory materials like graphite and alumina-mullite simply can't keep up. They warp, crack, and degrade, leading to frequent downtime and high replacement costs.

There is a superior solution: Custom-Shaped Reaction-Bonded Silicon Carbide (RBSiC/SiSiC) Saggers. Engineered for peak performance in the most demanding conditions, our saggers are not just containers; they are a critical investment in your production efficiency and product quality.

What is a Reaction-Bonded Silicon Carbide (RBSC) Sagger?

A Reaction-Bonded Silicon Carbide Sagger is a high-performance refractory container manufactured using advanced reaction-bonded sintering technology. This process fuses high-purity silicon carbide powder with a silicon binder at extreme temperatures, creating a dense, near-net-shape component with minimal shrinkage (≤3%). The result is a sagger with exceptional dimensional accuracy that can be customized into complex geometries—such as U-shaped, arched, or perforated designs—to meet your specific industrial needs.

Why Choose Our RBSiC/SiSiC Saggers? Key Features & Benefits

Our saggers are designed to deliver unmatched performance and a rapid return on investment.

• Unmatched High-Temperature Stability

  • Operate continuously up to 1380°C without softening or deforming.

  • Outperforms graphite (≤1200°C) and alumina-mullite (≤1300°C), enabling higher process temperatures and broader application range.

• Superior Thermal Shock Resistance

  • Withstands rapid temperature changes (e.g., quenching from 1300°C) without cracking or spalling, thanks to a low thermal expansion coefficient.

  • Eliminates costly failures during fast heating and cooling cycles.

• Exceptional Corrosion & Oxidation Resistance

  • Highly resistant to strong acids, alkalis, and oxidizing atmospheres.

  • Lasts 3-5x longer than graphite crucibles and 8-10x longer than alumina-mullite saggers, drastically reducing replacement frequency and maintenance costs.

• High Thermal Conductivity for Energy Savings

  • With 45 W/m·K thermal conductivity, our saggers ensure faster, more uniform heat distribution.

  • Reduce energy consumption by over 20% and improve product yield through consistent sintering.

• Custom-Designed for Your Process

  • We specialize in custom-shaped saggers. Whether you need slots, grooves, porous structures, or unique geometries, we can engineer a solution that fits your kiln and process perfectly.

  • Optional surface treatments (polishing, anti-stick coatings) further enhance performance.
