Abstract
A nanometre-class iron oxide powder with different shapes prepared through the reaction between Fe-ion solution and alkaline solution under the condition of introducing surfactant, and features that the shape of the said nanometre iron oxide particles can be controlled by regulating the proportion mix between the high-molecular and the low-molecular surfactants. Its advantages are fine and uniform granularity (10-30 nm), simple equipment and low cost.
Description
technical field [0001] The invention relates to a method for manufacturing nanometer materials, in particular to a method for manufacturing nanometer iron oxide powders of different shapes. Background technique [0002] Nanomaterials are new materials developed in recent years, which have shown a wide range of uses and excellent effects in various fields. Due to technical limitations, the particle size of iron oxide particles currently manufactured has not yet reached the nanometer level, which is far from meeting the needs of production and scientific research. The Chinese invention patent application with the application number 99114908 discloses a method for manufacturing nano-cobalt oxide, which is characterized in that surfactants are introduced into the chemical precipitation method to produce cobalt oxide with a particle size of 5-60 nm. It is carried out under heating, so the requirements for production equipment are high, and the cost is great...
