Metallurgical Slags

 

Silicon slag is a silicon-containing metallurgical material recovered during silicon alloy production. Depending on the grade, the silicon content can generally range from 30% to 70%. Other elements such as aluminum, carbon, sulfur and phosphorus vary according to the product grade and production batch.

For purchasing, we recommend confirming the required silicon content and impurity limits before quotation. A batch COA can be provided to confirm the actual chemical composition.

 

Silicon slag can be used as a silicon-bearing metallurgical material where the required chemistry and process conditions allow. Its suitability depends on silicon content, impurity limits, particle size and the target production process.

• Steelmaking silicon addition
• Deoxidation applications
• Foundry and alloy production
• Blended metallurgical raw material

If you have a specific furnace process or target composition, send us your required Si content and impurity limits so we can recommend a suitable grade.

 

Different production processes require different particle sizes and material forms. We can supply silicon slag according to the required grade, size and packing.

 

We control silicon slag quality from production and processing through packing and shipment. The actual inspection items are confirmed according to the agreed product specification.

• Raw material and production-process inspection
• Chemical composition testing according to product grade
• Particle size and appearance checking before packing
• Final batch inspection before shipment
• COA available for batch chemistry confirmation

 

We supply metallurgical materials directly from our production and processing system and support bulk export orders. Before quotation, we can confirm the required chemistry, particle size, quantity, packing and delivery conditions with you.

For regular orders, we can also support batch inspection, packing confirmation, export documentation and logistics coordination.

 

What is the silicon content of silicon slag?

Silicon slag can contain approximately 30%–70% silicon depending on the grade. The exact composition should be confirmed according to the agreed specification and batch COA.

Can you supply different silicon slag grades?

Yes. We can confirm the suitable grade according to your required silicon content, impurity limits and application.

Can silicon slag particle size be customized?

Different forms and particle sizes can be discussed according to your production process and order quantity.

Can I get a sample before placing a bulk order?

Samples can be arranged for product evaluation before a bulk order. Please contact us with your required grade and delivery information so we can confirm the sample arrangement.

What information should I provide for a quotation?

Please send your required silicon content, impurity limits, particle size, quantity, packing requirement and destination port. This allows us to quote the correct product instead of giving only a general silicon slag price.
