Description

Chromium Carbide CAS NO 12105-81-6 is a high-performance refractory ceramic compound known for its exceptional hardness, wear resistance, and thermal stability. This material is critical for enhancing the durability and service life of components operating under extreme abrasive and high-temperature conditions. It is an essential raw material for manufacturers in the metallurgical, tooling, and advanced coatings industries seeking to improve product performance.

Application

• Thermal Spray & Wear-Resistant Coatings: A primary component in powder form for high-velocity oxygen fuel (HVOF) and plasma spray processes to create hard, protective surfaces on industrial machinery, rolls, and extrusion screws.
• Hardmetal & Cermet Production: Used as a reinforcing phase in chromium carbide-nickel chromium (Cr3C2-NiCr) cermets and other metal matrix composites for cutting tools, seals, and bearing components.
• Welding & Hardfacing: Incorporated into welding rods and electrode coatings to deposit wear-resistant overlays on agricultural, mining, and oilfield equipment.
• Refractory Additives: Serves as an additive in specialized refractories to improve resistance to slag corrosion and thermal shock in high-temperature furnaces.
• Abrasive Materials: Utilized in the formulation of grinding media and abrasive grains for precision finishing applications.

Quality Control

Our Chromium Carbide is manufactured under controlled conditions to ensure batch-to-batch consistency and high performance. Quality is verified through a series of analytical and physical tests, including particle size distribution (PSD), chemical purity, phase composition (via XRD), and oxygen content analysis. A Certificate of Analysis (COA) detailing lot-specific results is provided with every shipment to guarantee compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). The product is moisture-sensitive (hygroscopic) and should be kept away from strong acids and strong oxidizing agents to prevent degradation. For long-term storage, consider using a desiccated environment.
