Specification of Abrasive Resistance Silicon Carbide SIC Ceramic Crucible

The abrasive resistance silicon carbide (SiC) ceramic crucible is designed for high-temperature industrial applications. It handles harsh environments like metal melting, chemical processing, and abrasive material handling. The crucible is made from high-purity silicon carbide. It is formed through advanced sintering techniques. This ensures a dense structure with minimal porosity. The material’s inherent hardness (Mohs scale 9-9.5) provides exceptional resistance to wear, erosion, and mechanical impact.

The crucible’s composition includes silicon carbide grains bonded with a silicon nitride or reaction-sintered matrix. This enhances structural integrity. It maintains stability under rapid temperature changes. The thermal shock resistance prevents cracking during heating or cooling cycles. The working temperature range is up to 1600°C in oxidizing atmospheres. It withstands 1800°C in inert or reducing conditions.

Surface finish is optimized to reduce material adhesion. This simplifies cleaning and extends service life. The crucible’s low thermal expansion coefficient (4.0×10^-6/°C) minimizes dimensional changes under heat. High thermal conductivity (120 W/m·K) ensures even heat distribution. This improves process efficiency.

Chemical inertness makes it resistant to acids, alkalis, and molten metals. It avoids contamination of processed materials. The product is available in custom sizes. Standard capacities range from 50 mL to 20 liters. Wall thickness varies between 5 mm and 25 mm. Options include lids, handles, or reinforced rims for specific handling needs.

Testing confirms abrasion resistance through ASTM G65 standards. Results show minimal mass loss under high-stress conditions. Typical applications include foundries, laboratories, and semiconductor manufacturing. It replaces traditional materials like clay-graphite or alumina. Performance is consistent in repeated cycles. Maintenance requirements are low.

The crucible’s durability reduces replacement frequency. Operational costs decrease over time. Compatibility with induction heating systems is verified. No pre-treatment is needed before initial use. Storage guidelines recommend keeping it dry to prevent surface oxidation. Handling instructions emphasize avoiding mechanical impacts during transport.

Applications of Abrasive Resistance Silicon Carbide SIC Ceramic Crucible

Abrasion-resistant silicon carbide (SiC) ceramic crucibles are highly durable tools designed for extreme conditions. They handle high temperatures, chemical exposure, and mechanical wear effectively. These crucibles are widely used across industries requiring reliable performance in harsh environments.

Metallurgy relies on SiC crucibles for melting metals like iron, aluminum, and copper alloys. They withstand temperatures above 1600°C without degrading. Traditional materials like clay or graphite fail under similar stress. SiC crucibles last longer, reduce contamination risks, and improve process efficiency.

Chemical processing industries use these crucibles to manage corrosive substances. Acids, alkalis, and molten salts react minimally with SiC ceramics. This makes them ideal for synthesizing compounds or testing reactive materials. Labs and production plants benefit from their stability and low maintenance.

Jewelry manufacturers depend on SiC crucibles for precise alloy mixing. The material’s resistance to thermal shock prevents cracks during rapid heating or cooling. Gold, silver, and platinum processing becomes safer and more consistent. Small studios and large factories both use them for repeatable results.

Glass and ceramics production requires crucibles that endure molten materials. SiC ceramics handle molten glass and ceramic slurries without eroding. Their thermal conductivity ensures even heat distribution, critical for quality output. Furnace operators prefer them for reducing downtime and material waste.

Mining and material science applications involve grinding or analyzing abrasive samples. SiC crucibles resist wear from hard minerals or powders. Researchers use them to prepare samples for testing. Their longevity cuts replacement costs in labs handling abrasive substances.

SiC ceramic crucibles adapt to diverse industrial needs. Their toughness, thermal properties, and chemical inertness make them indispensable. Industries prioritize them for tasks demanding precision, durability, and cost-effectiveness.
