Abstract
Silicon metal-containing agglomerates are produced by agglomerating a mixture of finely divided silicon metal-containing particles having a particle size parameter d50 of not more than 250 μm and in the dry state a silicon metal content of at least 10% by mass, at least one binder containing 90% to 98% by mass of silicon dioxide and having a specific surface area of 15 to 35 m2/g, and water, wherein the mass ratio between finely divided silicon metal-containing particles and binder in the mixture is from 80/20 to 99/1, and the resulting moist agglomerates have a water content of 5% to 15% by mass, and drying the agglomerates.

A process for producing silicon metal-containing agglomerates, comprising:
- agglomerating a mixture of finely divided silicon metal-containing particles having a particle size parameter d50 of not more than 250 μm and in the dry state a silicon metal content of at least 10% by mass, a
- binder containing 90% to 98% by mass of silicon dioxide and having a specific surface area of 15 to 35 m2/g, and
- water,
- wherein the mass ratio between finely divided silicon metal-containing particles and binder in the mixture is from 80/20 to 99/1,
- wherein the resulting moist agglomerates have a water content of 5% to 15% by mass based on the total weight of the agglomerates,
- and drying the agglomerates to form dried agglomerates.
