Microsilica, as a new raw material, is widely used in insulation and fire-resistant materials. It plays a significant role in improving the properties of不定形耐火材料（non-shape refractory materials）. Its performance enhancements include: 1) Traditional refractory materials have numerous pores, which are filled with microsilica, thereby increasing the volume density and reducing the porosity, leading to a notable enhancement in strength.
Micronized silicon powder has a strong activity, capable of forming colloidal particles in water. By adding an appropriate dispersant, its fluidity can be enhanced, thereby improving casting properties.
Micronized silica powder readily forms —Si-OH groups in water, displaying strong hydrophilic and active properties. It enhances the cohesion of refractory materials and significantly improves their high-temperature performance, extending the service life of refractory products.
Micronized silica powder is widely used in the refractory industry. Its practical applications include the following aspects:
Substituting pure aluminum oxide mud as refractory material. As an additive, it produces non-shape and shape refractory products, greatly improving their strength and high-temperature properties. Used as a whole ladle pouring binder and accelerator. Also serves as a binder, accelerator, and additive for other refractory products.
