The magnetic metal oxide nano particles, the magnetic intermetallic compound nano particles and methods of making them

摘要

The present invention metal oxides using ultrasonic irradiation in accordance with nano-magnetic particles and intermetallic compound nano-magnetic particles method is a nano- magnetic particles can be produced in large quantities as the particle size adjustment of a uniform size of several hundred nanometers by using environmentally friendly non-toxic metal salts as the raw materials , and materials , medical , electronic , the application in industrial fields such as optical and energy it is possible . In addition, by preparing the nanoparticles through the ultrasonic irradiation by using the surfactant compared with the prior art In the manufacture of nanoparticles , and the yield of nanoparticles can be produced in a yield close to 100% to about prevented from being lowered . ;
