活性氧化铝球是一种由氧化铝（Al₂O₃）制成的白色球状多孔性颗粒材料，具有高比表面积、强吸附性、高机械强度和优良的热稳定性，主要用作干燥剂、吸附剂（特别是饮水除氟）和催化剂载体。1百科核心性质与物理形态活性氧化铝球，亦称活性氧化铝瓷球，其核心特征在于独特的物理结构。它由氢氧化铝加热脱水制得，主要晶相为γ-Al₂O³。产品通常呈现白色（或微红色）球状，粒度均匀，表面光滑。其内在的多孔性和高分散度结构，赋予了它巨大的比表面积（通常不低于280 m²/g，工业品可达300 m²/g以上）和丰富的毛细孔道，这是其具备优异吸附和催化性能的基础
Activated carbon is a black, porous solid carbonaceous material.
Nano-crystalline material is a non-metallic mineral that exhibits adsorptive properties toward harmful gases—such as formaldehyde, benzene, and TVOCs—generated during interior decoration, as well as toward automotive odors and general indoor pollutants. Laboratory tests have demonstrated that, over
