Problems solved by technology

At present, the widely used method is magnetic separation, which uses a magnetic field to remove metal impurities. However, the magnetic field of traditional magnetic separators is small, it is difficult to remove trace metal impurities, and the degree of automation is low, resulting in poor stability of product batches. More importantly, Existing magnetic separators generally use water medium, which cannot be applied to magnetic separation of some special ceramic powders (such as aluminum nitride)
These problems greatly limit the application of magnetic separation in the preparation of high-purity ceramic powders
In view of the above problems, the present invention provides a magnetic separator with a new structure for wet magnetic separation, which not only increases the gradient magnetic field, can remove trace metal impurities, but also can use water or ethanol as a medium, and solves the problem of magnetic separation. The problem that the equipment cannot be quantitatively controlled or automatically operated

Description

technical field [0001] The invention relates to equipment for removing trace metal magnetic impurities in ceramic powder, belonging to the technical field of high-purity ceramic powder preparation, in particular to a fully automatic wet-process high-gradient magnetic field magnetic separation equipment. Background technique [0002] High-purity ceramic powder has high purity, good dispersion, high reactivity, complete and stable crystal structure, superior sound, light, electricity, magnetic and other properties, and is the basis for the preparation of high-performance new ceramic materials. High-tech fields such as ceramics, functional ceramics, bioceramics and fine chemical materials have been widely used. The chemical synthesis method is used to prepare high-purity ceramic powder. Although the purity is high and the impurity content is low, the cost is high, the output is low, and the batch stability is not good. These problems greatly limit its application range and fiel...
