Silicon Metal Granules

Silicon metal Granules are a by-product obtained during the production of standard silicon metal grades (such as 553, 441, 3303, etc.). Due to slight deviations in chemical composition or appearance, it does not meet the requirements of standard grades, but it still contains a high percentage of silicon and is widely used in various industries as a cost-effective substitute.

Introduction

Our Silicon Metal Granules are produced during the crushing and screening of high-purity Silicon Metal lumps (mainly grades 553 and 441). With uniform size and stable chemical composition, the granules are carefully selected to ensure consistent quality.

Typical Specifications (variable depending on batches)

Si: 83% – 97%, 65%-77%.
Fe, Al, Ca: higher than standard grades
Form: blocks, lumps, or crushed particles

Key Features

Lower cost compared with standard silicon metal
Good source of silicon content for metallurgy and foundry use
Flexible applications where strict chemical requirements are not necessary

Applications

Ferroalloy production

As a reducing agent and raw material

Steelmaking

As a deoxidizer substitute for standard silicon metal

Foundry industry

For cast iron inoculation and alloying

Chemical industry

As raw material for certain non-critical processes

Silicon metal granules provide an economic alternative for industries that require silicon content but can accept higher levels of impurities compared to standard silicon metal grades.
