1. Filling metal silicon powder into pores increases bulk density and reduces porosity, resulting in a significant increase in strength;
2. Metal silicon powder has strong activity and can form colloidal particles in water. Adding an appropriate amount of dispersant can enhance flowability and improve pouring performance;
3. Metal silicon powder has strong hydrophilicity and activity, which can enhance the cohesion of refractory materials, greatly improve high-temperature performance, and extend the service life of refractory products. It is widely used in the refractory industry.
4. Used in high-temperature industries such as steelmaking furnaces and kilns, with high practical value.
