Description
High-Purity Pressureless SiC Crucible | 1800°C Crack-Free · Fast Heat Transfer · Metal-Free Contamination
Description:

The pressureless sintered silicon carbide crucible is a high-performance ceramic deep-bottom container fabricated from high-purity silicon carbide (SiC) powder using advanced pressureless sintering technology. Renowned for its exceptional resistance to high temperatures, corrosion, oxidation, and thermal shock, along with superior thermal conductivity, this product is widely utilized in metallurgy, chemicals, semiconductors, lithium-ion battery materials, electronic components, and ceramic powder sintering.

Typical application:

Metallurgy: Melting non-ferrous metals (gold, silver, copper, aluminum, zinc) and rare metal alloys.

Semiconductors & Electronics: Crystal growth, purification of high-purity materials.

Chemicals & Ceramics: Powder sintering, high-temperature reaction vessels.

Lithium-Ion Battery Materials: High-temperature processing of cathode/anode materials.

Research & Laboratories: Severe environments such as high-temperature melting and thermal analysis.

Feature:

Customizable Dimensions

Manufacturing Process:

Utilizing ultra-fine SiC powder with minimal sintering aids, the crucible is pressureless sintered at 2000-2150°C. Solid-phase or liquid-phase sintering techniques achieve densification, ensuring a pore-free, stress-free structure with uniform performance.

Advantages & Value:

Long Lifespan: Wear and corrosion resistance reduce replacement frequency.

Energy & Cost Savings: Rapid heat transfer shortens melting cycles.

Purity Assurance: Metal-free, ideal for high-purity material processing.

Customization: Tailored shapes, sizes, and properties to meet specific needs.
