编者按： 刚刚过去的2025年，山东大踏步迈入10万亿大省行列，经济社会高质量发展引发全国关注。 即日起，凤凰网山东推出"再启新程——凤观齐鲁2025"年度盘点策划，从全省统筹、区域联动、鲁企作 为等多个维度，解码山东跨越十万亿的底层逻辑，深度展现奋进齐鲁的生动实践，积极展望"十五五"开 局新篇，共同期待山东以更强担当、更实举措，持续书写高质量发展的精彩篇章。 在中国北方经济版图上，山东以超10万亿GDP稳坐"头把交椅"。而在齐鲁大地的转型浪潮中，有一座城 市正悄然完成一场"静默革命"。 它曾因胜利油田而名震全国，如今却不再靠"黑金"吃饭；它曾被贴上"一油独大"的旧标签，今天却在新 材料、绿电、零碳制造等赛道频频"亮剑"。 这座城市，就是东营。 早在2018年，东营就悄悄踏上了传统能源产业的升级转型之路。这一年，山东获批建设全国首个新旧动 能转换综合试验区，东营随之全面启动以新旧动能转换为核心的系统性产业结构调整。 成效迅速显现。2024年，东营石化产业实现营业收入6764.5亿元，约占全省的1/4。目前化工产业增加 值占规模以上工业的比重，已反超炼油产业4个百分点以上。"十四五"期间，化工行业正式取代炼油， ...

氧化铝，以化学式Al2O3表示的话，其所指十分明确，即仅以铝元素和氧元素组成的化合物。在广义上，氧化铝往往被认为是铝的氧化物与铝 的氢氧化物等的统称，是由铝、氧和氢组成的一类化合物。因此，氧化铝又被分为无水氧化铝和水合氧化铝。 无水氧化铝即我们所熟知的α-Al2O3、β-Al2O3、γ-Al2O3等不同晶型的氧化铝，国内发现的无水氧化铝的晶型有九种以上。水合氧化铝实际上 是由Ａl3+、O2-和OH-构成的，其中并不存在真正的水分子，只是由于习惯沿用至今，其水合物经过高温锻烧后都可转变成α-Al2O3。常见的 水合氧化铝为工业氢氧化铝、拜铝石、诺铝石、拟铝石、软铝石、硬铝石、托得石等。 由此可见，氧化铝家族是多么的庞大，应用注定十分广泛，这也难怪各行各业都有不同氧化铝厂家的身影了。下面我们盘点6种常见的氧化铝 产品及其代表性企业。 从应用来说，氧化铝可分为冶金级氧化铝与非冶金级氧化铝（即精细氧化铝）。冶金级氧化铝只用作金属铝的生产原料，工业生产中使用的铝 材料均来源于它，看似应用单一，但其占比可达氧化铝的90%以上，精细氧化铝占比不足10%。可以说冶金级氧化铝产量基本代表了某个国家 的氧化铝整体产量。 我国是氧 ...
