1. a kind of method for preparing the microballoon comprising lanthanum series metal phosphate complex compound, methods described includes:

  • A () provides organic lanthanide metal-complexed thing microballoon, wherein, based on the gross weight of the microballoon, the lanthanide series metal is presentAmount be more than 20 weight %, and organic lanthanide metal-complexed thing microballoon have less than 1 weight % adhesive, wherein, instituteState the organic ligand that organic lanthanide metal-complexed thing forms complex compound including lanthanide ion and with the lanthanide ion;

    AndWhat b () was then replaced with phosphate in the soft chemical reaction in organic lanthanide metal-complexed thing microballoon described organic matches somebody with somebodyAt least a portion of body,Wherein, the gross weight based on the microballoon, the amount that the lanthanide series metal is present in the microballoon of gained is more than 20 weight %,And wherein, the lanthanide metal-complexed thing in the microballoon of gained includes lanthanide ion and phosphateWherein, the microballoon has the diameter of 200nm~300 μ
