摘　　要：研究了拟薄水铝石的酸分散性能。结果表明，不同原料路线、不同制备方法、不同加料速度以及样品中是否含硅等都对酸分散性能有较大的影响。对所测得的酸分散指数与样品的成型效果、粒度大小及其它性能进行了关联。发现平均粒度小和成型效果好的样品有较大的酸分散指数，但酸分散指数与样品的孔结构无直接关系。The acid dispersion property of pseudoboehmite was studied. The test results showed that raw material, precipitation method, feeding speed and Si modification had great influences on dispersion property. The measured dispersion index (DI) was correlated with the sample extrusion property as well as average particle size. Sample with a higher DI value can be extruded easily and corresponded to a small average particle size. However no correlation was observed between pore structure and DI value.
