Synthetic method for producing light-burned magnesia-alumina spinel by one-step method
The invention relates to a synthetic method for producing light-burned magnesia-alumina spinel by a one-step method, which comprises the following steps: mixing high-purity light-burned magnesia powder produced by a suspension furnace as a magnesia raw material with industrial alumina powder, introducing a small amount of active magnesia-alumina spinel as a seed crystal, mixing with a self-made high-efficiency additive, finely grinding, and pressing into balls; and sintering to obtain the magnesia-alumina spinel raw material. The method solves the problem of low grade of the magnesium aluminate spinel produced by the traditional one-step method, and has the characteristics of simple process, low calcining temperature, lower cost, high product volume density and purity and capability of improving the market competitiveness of the product.
本发明涉及一种一步法生产轻烧镁铝尖晶石的合成方法,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,同时引入少量的活性镁铝尖晶石作为“晶种”并辅之以自制高效外加剂一起混合、细磨、压球,并烧结成镁铝尖晶石原料,既解决了传统一步法生产镁铝尖晶石品位低的问题,同时又具有工艺简单、煅烧温度低、成本较低,产品体积密度和纯度高,可提高产品市场竞争力的特点。
