Scale inhibition target material as well as preparation and application thereof

The invention provides a scale inhibition target material and preparation and application thereof, in the scale inhibition target material, barium ferrite is a matrix, Cu, Sn, Ni, Cr, Ti and Zr are uniformly distributed in the matrix in a dispersed form, and in the target material, the barium ferrite accounts for 84 wt% to 95 wt%, the Cu accounts for 0.6 wt% to 2.4 wt%, the Sn accounts for 0.9 wt% to 3.6 wt%, the Ni accounts for 0.8 wt% to 2.4 wt%, the Cr accounts for 1.2 wt% to 3.6 wt%, the Ti accounts for 0.5 wt% to 2.0 wt%, and the Zr accounts for 0.5 wt% to 2.0 wt%. A coating layer prepared from the scale inhibition target material provided by the invention is stable in chemical property, and does not pollute a water body like chemical scale inhibition after being used for a long time. The coating layer provided by the invention can be in close contact with a water body and does not need to penetrate through a water pipe and other substances like conventional magnetic field scale inhibition, so that the r
