Nucleation and growth and the use of magnetic metallic oxide nano- particle

摘要

(57) Abstract Being method in order to manufacture the nano- particle which coating is done with magnetic metallic oxide, a below) - g) including process, the method of becoming: a) making the aqueous solution contact which includes the polymer metal chelation medicine of solubility with the solubility metal salt of 1 kinds, or more being the process which makes the metal ion form, in this case among the said metal ions at least 1 kinds are something which can form magnetic oxide, it exists at the quantity where the said metal ion does not exceed the connection talent of the aforementioned chelation medicine substantially, the said process; b) the process which it tries to exist oxidation when the aforementioned metal ion has been necessary for the formation of magnetic oxide; c) the process which maintains the pH of solution in the range of 7 or more; d) the process which adds the aforementioned metal salt of the additional quantity to solution; e) the process which it tries to exist oxidation when the said additional metal ion has been necessary for the formation of magnetic oxide; f) the process which maintains the pH of solution in the range of 7 or more; Although g) process d) - f) operation, the single dispersed nano- particle which coating is done is obtained with magnetic metallic oxide, necessary frequency the process which is repeated continually.
