Silicon Carbide Alloy 75% – Product Overview

Silicon Carbide Alloy 75% represents our premium grade for metallurgical and refractory applications. With a minimum silicon carbide content of 75% and tightly controlled impurities (Fe₂O₃ ≤2.0%, Al₂O₃ ≤1.5%), it offers superior performance for clean steel production, high-efficiency inoculation, and advanced refractory shapes.

Product Core Advantages

High SiC Content: Minimum 75% SiC maximizes exothermic energy and deoxidation power per unit weight.
Low Impurities: Reduced Fe₂O₃ and Al₂O₃ minimize oxide inclusions, ideal for critical steel grades.
Optimized Carbon: Balanced free carbon provides controlled recarburization without excess slag foaming.
Premium Sizing: Precision screening ensures consistent particle distribution for rapid dissolution.
Versatile Use: Suitable for the most demanding metallurgical processes and high-temperature ceramics.

Typical Application Areas

Silicon Carbide Alloy 75% is essential in many industrial processes:

Specialty Steelmaking: As a primary deoxidizer for bearing steels, spring steels, and other clean steel grades.
Ductile Iron Production: Inoculant to achieve nodularity and minimize carbide formation.
High-Grade Refractories: Raw material for SiC kiln furniture, crucibles, and sliding gate plates.
Advanced Ceramics: For manufacturing sintered silicon carbide components.
Abrasive Industry: Base material for high-quality grinding wheels and coated abrasives.

Application Guidelines – Silicon Carbide Alloy 75%

Silicon Carbide 75% is a versatile material with the following primary applications:

Premium Steel Deoxidation

Ideal for ladle furnaces and refining stations where low oxygen content and inclusion cleanliness are critical. SiC 75% provides a strong exothermic reaction and efficient oxygen scavenging. Typical addition rates: 0.5-3 kg per ton of steel.

High-Performance Iron Inoculation

In production of ductile and compacted graphite iron, SiC 75% acts as a powerful inoculant, promoting graphite nodule count and reducing chilling tendency. Often used in combination with other inoculants.

Slag Conditioning & Desulfurization

Helps to create reducing slag conditions and aids in desulfurization in secondary metallurgy.

Typical Addition Rates (Steel & Iron)

Addition rates vary by application: 0.5-2% for deoxidation, 0.1-0.4% for inoculation. Our technical team can assist with optimal sizing and addition practices.

Frequently Asked Questions – Silicon Carbide Briquette 75%

Why choose SiC 75% over lower grades for steelmaking? +

SiC 75% offers the highest purity among our metallurgical grades. Its lower impurity levels (Fe₂O₃, Al₂O₃) mean fewer oxide inclusions in the final steel, making it the preferred choice for critical applications such as tire cord steel, bearing steel, or any grade requiring stringent cleanliness standards.

Is it possible to entrust a third-party inspection to check the quality before shipment? +

Certainly, we support third-party inspections by internationally recognized quality inspection agencies such as SGS and BV to verify product quality before shipment. The inspection covers product appearance, weighing, dimensions, and chemical composition analysis. The entire inspection process will be documented with photos and written records, which will be provided to you together with the final inspection report. This ensures you have no concerns regarding product quality.

Do you provide a certificate of analysis with each shipment? +

Absolutely. Every batch of Silicon Carbide Alloy 75% is tested in our ISO 17025 accredited laboratory, and a Certificate of Analysis (COA) showing SiC, F.C., Fe₂O₃, Al₂O₃, and other elements is provided with the shipping documents.

What is your production capacity for Silicon Carbide briquette? +

We have an annual production capacity exceeding 40,000 metric tons of silicon carbide across various grades, including SiC 65%, 70%, and 75%. We can accommodate both containerized and bulk vessel shipments.
