High Carbon Silicon

What is High Carbon Silicon?

High Carbon Silicon (also known as Silicon Carbon Alloy) is a composite alloy produced as a by-product of metallic silicon manufacturing. It combines silicon (Si) and carbon (C) as its main elements, offering a cost-effective alternative to traditional ferrosilicon and carburizing agents in steelmaking and foundry operations.

Key Applications

Steelmaking

Deoxidizer: Removes oxygen from molten steel rapidly and effectively
Alloying Agent: Adds silicon and carbon to adjust chemical composition and mechanical properties—improving strength, hardness, and elasticity of steel
Slag Collector: Helps oxides coagulate quickly for easier filtration, producing purer steel

Casting Industry

Inoculant: Promotes graphitization in cast iron, reduces white mouth tendency, increases graphite sphere count, and improves casting integrity
Spheroidizing Agent: Aids graphite spheroidization, enhancing toughness and ductility of cast iron

Other Applications

Ferroalloy production (as reducing agent)
Aluminum processing industry
Refractory materials and wear-resistant components
Powder metallurgy additives

Typical Specifications

Available Sizes: 0–3mm (powder), 1–3mm, 1–10mm, 10–50mm, 10–100mm (blocks)

Customized compositions and sizes can be produced upon request to meet specific customer requirements.

Why Choose High Carbon Silicon?

Cost Savings – Reduces alloy addition costs by 15–30% compared to using ferrosilicon and carbon raisers separately

Dual Function – Provides both deoxidation and carbonization in one product, simplifying the process

High Absorption – Absorption rate exceeds 85–90%, minimizing waste

Low Impurities – Sulfur and phosphorus kept at ≤0.05% for clean performance

Environmental – Reduces fluorspar usage and lowers toxic gas emissions
