Silicon Slag With High Silicon

 Product Overview

Silicon Slag with High Silicon is a by-product of silicon metal or ferrosilicon smelting, but don't let that fool you - it packs serious value. With a silicon content ranging from 50% to 70%, this material serves as a cost-effective alternative to traditional ferrosilicon in steelmaking and casting. It is widely used as a deoxidizer, alloying agent, and slag conditioner, offering a perfect balance between performance and price.

Silicon (Si): 50% – 70%

Calcium (Ca): 1% – 5%

Carbon (C): ≤6%

Sulfur (S): ≤0.10%

Phosphorus (P): ≤0.05%

Size: 0–10 mm, 10–50 mm, or custom sizes

Packaging: 1MT jumbo bags or per customer request

At Golden Ltd., maintaining high-quality and consistent silicon slag is a top priority. Here's how we do it:

🔬 Strict Raw Material Selection
We source only from reliable smelters with stable output quality. All incoming materials are inspected to ensure they meet our silicon content and impurity standards.

⚙️ Advanced Processing & Screening
Our silicon slag undergoes crushing, screening, and magnetic separation to ensure uniform particle size, reduced impurities, and optimal silicon recovery.

📈 Comprehensive Lab Testing
Each batch is tested in-house for:

Silicon content (Si)

Carbon, Sulfur, Phosphorus

Size distribution
We provide detailed COAs (Certificates of Analysis) with every shipment.

🔄 Stable Production Process
We follow a standardized production protocol, ensuring batch-to-batch consistency in chemical composition and physical form.

🔁 Sampling & Third-Party Verification
Random samples are also sent for third-party testing to cross-verify internal lab results, especially for international orders.

🌍 Customer Feedback Loop
We maintain close communication with our clients and adjust specifications based on feedback to ensure the material performs optimally in their specific processes.
