| Abstract: | This paper deals mainly with the preparation, certain properties and the hydrogen reduction of di-amine and ethylenediamine tungstates. The effects of self-reductivity of such tungstates during hot de-compostion on the W oxide powder reduction process has been studied. It is found that by combiningthe self-reductivity with common hydrogen reduction, fine W powders with BET surfaces>20m~2/gcan be prepared. The essence of Selfreductivity is discussed and the possibility of the application of suchtungstates to submicron W powder production is considered. |
