<P>PROBLEM TO BE SOLVED: To provide an apparatus for producing hydrogen selenide which improves the yield of the hydrogen selenide, and can produce high-purity hydrogen selenide continuously. <P>SOLUTION: The apparatus for producing the hydrogen selenide includes: a route 12 and a route 13 for charging hydrogen and metallic selenium, respectively, to a reactor 11 that generates the hydrogen selenide from the hydrogen and the metallic selenium; a route 14 for purging a reaction gas that is generated in the reactor and contains the hydrogen selenide; a hydrogen selenide collector 15 for collecting the hydrogen selenide in the reaction gas; heating and cooling devices 16a and 16b which can be switched between a cooling operation for cooling the reaction gas to collect the metal selenium and a heating operation for heating the hydrogen to evaporate the metallic selenium; a metal selenium charging vessel 29 that has purge routes 35a and 35b; and a gas circulation route 17 for purging the reaction gas from the hydrogen selenide collector and returning it to the hydrogen charging route. <P>COPYRIGHT: (C)2012,JPO&INPIT |
