内容概要：黄磷（P4）又称白磷，由磷矿化学加工得出，呈黄白色蜡状，具有光泽的固体，有立方体 和六方体两种晶体结构，室温下为立方体。其化学性质活泼，除了碳、硅和硼，几乎所有元素与它均能 直接生成相应磷化物。黄磷生产方法有电炉法和高炉法两种，我国以电炉法为主，这种方法实收率高、 产品纯度高。目前世界的黄磷供给呈现中国、越南、哈萨克斯坦"三足鼎立"状态，中国黄磷供给规模远 超其他地区。2024年全球黄磷产能为175.5万吨，其中中国贡献了全球82.6%的黄磷产能，为145万吨； 其次越南、哈萨克斯坦产能分别占比8.5%、5.4%。自改革开放以来，我国黄磷产业取得了举世瞩目的 发展，2014年我国黄磷产能达到240万吨，产量首次突破百万吨大关，达102.5万吨。近年来各级政府陆 续出台了黄磷相关环保政策，进而导致中国黄磷产量自2016年起开始大幅下降。2020-2025年期间，受 环保政策不断收紧等因素影响，中国黄磷产量呈波动态势，2024年为期间最高值，达85.71万吨，同比 增长16.5%；2025年1-9月黄磷产量为74.15万吨，预计全年黄磷产量为95万吨左右。中国黄磷生产集中 在云贵川鄂4省，主要系这些地区 ...
