1results about How to "Realize batch preparation" patented technology

The application discloses a kind of UN powder's quick preparation method, solve the carbon-thermal reduction-nitriding reaction method in prior art difficult to obtain high-purity UN powder, arc smelting method high cost, long cycle problem.A kind of UN powder's quick preparation method of the application, UO2 powder is reduced into metal uranium using metal reduction method, then using reaction heat makes metal uranium and nitrogen gas nitriding reaction, obtains UN powder.The application is more efficient, the reaction process is faster, more sufficient, UN production cycle is compared with arc smelting method greatly shortened, even shorter than carbon-thermal reduction method, can realize the batch preparation of high-purity UN powder in very short time.
