Silicon Carbide Alloy 65% – Product Overview

Silicon Carbide Alloy 65% is a synthetic compound produced through high-temperature smelting of quartz sand and petroleum coke. It offers a minimum silicon carbide content of 65%. Our SiC 65% grade features a balanced composition of active SiC and free carbon, making it an efficient deoxidizer and recarburizer in ferrous metallurgy. It also serves as a high-quality raw material for refractory shapes and abrasives.

Product Core Advantages

High SiC Content: Minimum 65% SiC ensures strong deoxidation and exothermic effect in molten steel and iron.
Dual Deoxidation & Recarburization: Provides both oxygen removal and carbon pickup in a single addition, improving efficiency.
Consistent Quality: Tight control of impurities (Fe₂O₃, Al₂O₃) ensures predictable metallurgical performance.
Custom Sizing: Available in lumps, granules, or powder to match furnace charging and injection systems.
Cost-Effective: Replaces more expensive alloys like ferrosilicon and carbon raiser combinations.

Typical Application Areas

Silicon Carbide Alloy 65% is essential in many industrial processes:

Steelmaking (EAF, AOD, LF): As a deoxidizer and slag conditioner to improve steel cleanliness and reduce oxygen content.
Iron Foundries: Inoculant for gray and ductile iron to promote graphite formation and improve mechanical properties.
Refractory Industry: Raw material for producing SiC-based refractory bricks, kiln furniture, and crucibles.
Abrasive Tools: Used in grinding wheels and abrasive papers due to its hardness.
Ceramic Components: For manufacturing high-temperature structural ceramics.

Application Guidelines – Silicon Carbide Alloy 65%

Silicon Carbide 65% is a versatile material with the following primary applications:

Steel Deoxidation

Added to electric arc furnaces, ladles, or tundishes. SiC reacts with dissolved oxygen to form SiO₂ and CO, effectively reducing oxygen content while providing exothermic heat. Typical addition rates: 1-5 kg per ton of steel, depending on initial oxygen levels.

Slag Conditioner

Helps to reduce FeO in slag, improving slag fluidity and metal recovery. Also aids in desulfurization.

Typical Addition Rates (Steel & Iron)

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

Frequently Asked Questions – Silicon Carbide Briquette 65%

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.

What is the difference between Silicon Carbide 65% and higher grades like 70% or 75%? +

SiC 65% has a minimum silicon carbide content of 65%, with higher free carbon and slightly higher oxide impurities (Fe₂O₃, Al₂O₃). It is a cost-effective choice for bulk metallurgical applications like steel deoxidation and iron inoculation, where the high purity of SiC 75% or 88% is not required.

Can SiC 65% replace ferrosilicon in steelmaking? +

Yes, SiC 65% can partially replace ferrosilicon and carbon raisers. It provides both silicon and carbon for deoxidation and recarburization. However, the exact replacement ratio depends on your furnace practice and target chemistry. Our technical team can help optimize the substitution.

What sizes are best for induction furnace addition? +

For induction furnaces, granules in the range of 2-15mm or 1-6mm are recommended to ensure rapid dissolution and good recovery. Lumps 10-50mm can also be used if charged with the scrap.

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

Absolutely. Every batch of Silicon Carbide Alloy 65% 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.
