一般描述
氧化钙 (CaO)又称生石灰，因其高反应性和多用途性而成为一种广为人知的离子化合物。该产品的粒径<160 nm，密度 3.3 g/mL（25 °C），微量金属含量 98%。氧化钙为白色固体外观，吸湿性强，易与空气中的水分发生反应。氧化钙广泛应用于各种工业应用，包括水泥和玻璃的生产，在其中充当助熔剂。它还用作钢铁工业中的炉渣调节剂，以及通过水合生产氢氧化钙。此外，CaO 还用于在水处理工艺中调节 pH 值，以及生产钙基化学品。CaO 还用于：纳米粒子的合成：氧化钙是合成钙基纳米材料的前体，可用于催化和药物输送。 玻璃制造：助熔剂：CaO 在玻璃制造中用作助熔剂，以降低二氧化硅的熔点，改善熔融过程，并增强玻璃性能。
应用
- 氧化钙用于可持续混凝土生产：研究氧化钙增强碱激发矿渣混凝土抗碳化性，说明它的可持续建筑应用(P Shi et al., 2024)。
- 农工业废物产氧化钙用于牙科应用研究用废蛋壳合成氧化钙纳米颗粒，关注它们促进牙组织再生的潜力(J do Amparo Madureira et al., 2024)。
- 氧化钙增强高灰煤泥修复：讨论在高灰煤泥来源的土壤改良剂中添加氧化钙，它可增强净化环境的吸附性(Y Tian et al., 2024)。
- 开发氧化钙基活化剂：用废弃的氧化钙飞灰作为天然橡胶硫化的活化剂，减少氧化锌需求并提高环境可持续性(W Naebpetch et al., 2024)。
