Production Of Nanosize Particles by Gas Phase Synthesis Using MOCVD

摘要

A system for the production of nanoparticles incorporating MOCVD has been assembled at the National High Magnetic Fields Laboratory. The system comprises: 1. a microwave plasma deposition system utilizing a powder delivery system; 2. a supercritical fluid system; and 3. three vaporizers, one of which includes a liquid delivery system. The use of the plasma system will aid in the development of novel composite materials. The supercritical fluid system will be used to make nanoparticles from metalorganic compounds or noble metals. The different vaporizer systems will make it possible to use volatile solid or liquid precursors for deposition onto the surface of the nanoparticies. This coating technique is aimed at producing composite and/or magnetoresistive materials. Evaluation of the manual system controls are currently being accomplished. Computer control designs are well underway and being tested. Any information gathered during the manual control testing will be implemented into the computer control design.
