白色结晶粉末状，化学纯度高，性能稳定，具有良好的烧结性能。是生产高级陶瓷，高级耐火制品，耐磨、耐热、耐腐蚀器件的基本原料。活性α-AI₂0₃具有吸水率低，流动性好，烧结密度大，高温强度高等特点。特别适用于生产不定型耐火材料等。

A white crystalline powder with high chemical purity and stable properties, it exhibits excellent sintering characteristics. It serves as a basic raw material for the production of high-grade ceramics, high-grade refractory products, and wear-resistant, heat-resistant, and corrosion-resistant components. Active α-Al₂O₃ is characterized by low water absorption, good flowability, high sintered density, and high high-temperature strength. It is particularly suitable for the production of unshaped refractory materials, among other applications.
