Synthesis method of light-burned magnesia-alumina spinel intermediate
The invention relates to a synthesis method of a light-burned magnesia-alumina spinel intermediate, which comprises the following steps: by using high-purity light-burned magnesia powder produced by asuspension furnace as a magnesia raw material, mixing with industrial alumina powder, carrying out pre-reaction, and carrying out medium-temperature calcination synthesis to obtain the high-activityhigh-purity magnesia-alumina spinel intermediate. The method not only provides a raw material source for further high-temperature calcination production of high-purity high-volume-density magnesium aluminate spinel, but also opens up a new way for rich magnesite resource utilization owned by Liaoning Province of China, can further expand deep processing of magnesite to improve the additional valueof the product, and has huge economic and social benefits.
本发明涉及一种轻烧镁铝尖晶石中间体的合成方法，以悬浮炉生产的高纯轻烧氧化镁粉为氧化镁原料与工业氧化铝粉混合预反应，并经中温煅烧合成生产得到高活性高纯镁铝尖晶石中间体，既为进一步高温煅烧生产高纯高体密镁铝尖晶石提供了原料来源，同时又为我国辽南地区拥有的丰富菱镁矿资源利用开辟了新途径，可进一步拓展菱镁矿的深加工以提高其产品的附加值，经济效益和社会效益巨大。
