板状刚玉粉 200目以下
板状刚玉粉200目以下，Al₂O₃≥99.2%，作为低水泥浇注料结合相填充料，适用于钢包、高炉铁沟及石化炉底衬体。
// 主要特性
- Fine <200 mesh gradation filling inter-granular voids to minimize castable porosity
- High chemical purity Al₂O₃ 99.2% preventing flux contamination in the bond phase
- Low SiO2 ≤0.05% ensuring phase stability without secondary mullite formation
- Excellent reactivity with calcium aluminate cement for superior green and fired strength
