The invention relates to a ferrite surface roughening liquid and its application in the ferrite surface roughening treatment and metallization treatment. The ferrite surface roughening solution includes water, an acid and a salt, and the molar ratio of the acid and the salt is 1:(0.002-11); the acid is an organic acid and/or Inorganic acid; salt is at least one of alkali metal chloride, alkaline earth metal chloride, alkali metal fluoride and water-soluble ammonium salt; organic acid is at least one of methanesulfonic acid, formic acid, citric acid and oxalic acid; The inorganic acid is at least one of sulfuric acid, nitric acid, boric acid, iodic acid, selenic acid, sulfurous acid, nitrous acid and phosphoric acid; the alkali metal chloride is at least one of sodium chloride and potassium chloride; alkaline earth metal chloride It is at least one of magnesium chloride and calcium chloride; the alkali metal fluoride is at least one of sodium fluoride and potassium fluoride. The ferrite surface roughening solution has good roughening effect, is very environmentally friendly, and has wide application prospects. |
