Refractory Materials Industry
Application of Zirconium Microsilica Powder in High-Temperature, Abrasion-Resistant Refractory Castables
Application Research on Heat-Resistant and Erosion-Resistant Castable Materials
- 1. Optimized thermomechanical stability: By adjusting high-temperature liquid phase characteristics, the material's high-temperature flexural strength (HMOR) is significantly enhanced, preventing softening or deformation.
- 2. Enhanced slag resistance and permeation resistance: The denser high-temperature phases (e.g., mullite) formed by zirconium microsilica create an effective chemical barrier on the material surface.
- 3. Multi-mechanism synergistic thermal shock resistance: Engineering practice demonstrates that the microphase transformation mechanism introduced by zirconium microsilica, combined with optimized matrix modulus, reduces damage to refractories caused by thermal stress.
