白刚玉耐火骨料 Al2O3 99% 0-3mm
白刚玉耐火骨料，Al2O3≥99%，粒径0-3mm，杂质极低，高耐火度，适用于钢包工作层、中间包高纯浇注料及石化加热炉底部衬里。
// 主要特性
- Al2O3 ≥99% purity providing excellent chemical stability against molten steel slag attack
- High refractoriness under load (RUL >1700°C) for demanding steel and petrochemical service
- Low SiO2 and Fe2O3 minimizing contamination risk in high-purity monolithic refractory castables
- Excellent thermal shock resistance from controlled crystal structure and low open porosity
