High-Performance Industrial Silicon Carbide (SiC) - ZhenAn International
Introduction to Industrial-Grade SiC
In the competitive landscape of modern metallurgy and heavy manufacturing, maintaining a balance between high-quality output and lean operational costs is paramount. Traditional deoxidation methods often involve expensive ferroalloys that add complexity to the furnace charge.
ZhenAn's Industrial Silicon Carbide (SiC) serves as a robust, multifunctional reagent. By integrating both silicon and carbon into a single stable crystalline structure, it allows for streamlined alloying processes. Our industrial-grade SiC is prized for its extreme thermal stability and aggressive deoxidation capabilities, making it a cornerstone for efficient steel and iron production.
Technical Parameters & Chemical Grades
We offer various grades of industrial silicon carbide, meticulously refined to meet the specific chemistry targets of our global clients.
| Chemical Component | SiC Grade 88 | SiC Grade 90 | SiC Grade 95 (Premium) |
| SiC Content | ≥ 88.0% | ≥ 90.0% | ≥ 95.0% |
| Carbon (Free) | ≤ 4.5% | ≤ 3.0% | ≤ 1.5% |
| Iron Oxide (Fe2O3) | ≤ 2.5% | ≤ 1.5% | ≤ 0.8% |
| Aluminum (Al2O3) | ≤ 1.8% | ≤ 1.2% | ≤ 0.6% |
| Total Moisture | ≤ 0.5% | ≤ 0.4% | ≤ 0.2% |
Primary Industrial Sectors & Applications
1. Advanced Steelmaking
Industrial SiC is a high-velocity deoxidizer. When introduced into the melt, it rapidly reduces oxygen levels, leading to cleaner steel with superior mechanical properties and reduced gas porosity.
2. Foundry & Casting Operations
Used as an effective inoculant in gray and ductile iron casting, SiC promotes graphite precipitation. This results in enhanced tensile strength and improved machinability of the final cast components.
3. High-Temperature Refractories
With a sublimation point near 2700°C, industrial SiC is utilized in the synthesis of kiln furniture, crucibles, and high-heat furnace linings that must endure extreme thermal cycling.
4. Wear-Resistant Coatings
Due to its 9.5 Mohs hardness, it is incorporated into industrial flooring and surface treatments to provide maximum abrasion resistance.
Thermodynamic Advantages in Metal Smelting
Utilizing Industrial SiC provides a distinct thermodynamic edge over standard carbon raisers:
Exothermic Heat Release: The chemical reaction between SiC and oxygen releases thermal energy, which helps sustain the furnace temperature and lowers energy consumption per ton.
Dual Alloying Effect: A single addition provides both Si and C, simplifying the charging sequence and reducing inventory management complexity.
Slag Management: SiC decreases slag viscosity, facilitating better separation of the metal and impurities during tapping.
