Description

Wynalazek niniejszy dotyczy sposobu wytwarzania metali albo ich wodorków lub azotków w stanie sproszkowanym. W tym celu przygotowujemy przedewszystkiem ortec (amalgamat) metalu, który laczy sie z wodorem lub z azotem, ogrzewamy ja w prózni, w atmosferze wodoru lub azotu, sto¬ sownie do tego, czy chodzi o produkcje pro¬ szku czystego metalu, czy tez wodorku lub azotku tego metalu.Sposób ten pozwala na sproszkowanie nietylko metali ziem alkalicznych, jak np. baru, ale równiez i wszelkich metali, jak np, ceru, które daja amalgamaty. Moznosc proszkowania metali posiada wielka donio¬ slosc dla procesu wiazania azotu. Tak np. chrom i mangan w postaci bryl nie azotuja sie prawie wcale nizej 1000° C, w stanie zas sproszkowanym przy pomocy destylowania ich amalgamatów spalaja sie w azocie juz w temperaturze ponizej 300° C, Metale, wodorki oraz azotki metali w stanie sproszkowanym moga stanowic kata¬ lizatory przy wiazaniu azotu, a szczególniej przy syntezie amon jaku bez cisnienia lub pod niskiem cisnieniem i w niskiej tempe¬ raturze.Przyklad. Na drodze elektrolitycznej -wytwarzamy ortec chromu, która zamierza¬ my naazotowac. Ortec te destylujemy w prózni i otrzymujemy chrom w stanie spro¬ szkowanym. Mozna podobniez destylowac ortec w azocie, a otrzymamy wówczas bez¬ posrednio azotek chromu. PLThe present invention relates to a process for the production of powdered metals or their hydrides or nitrides. For this purpose, we prepare, first of all, an ortec (amalgam) of a metal that combines with hydrogen or nitrogen, we heat it in a vacuum, in an atmosphere of hydrogen or nitrogen, according to whether it is the production of pure metal powder or hydride. or nitride of this metal. This method allows the pulverization of not only alkaline earth metals, such as barium, but also all metals, such as cerium, which give amalgams. The pulverization capacity of metals is of great importance for the nitrogen fixation process. For example, chromium and manganese in the form of lumps do not nitrogen almost at all below 1000 ° C, while in the powdered state, by distilling their amalgams, they burn in nitrogen already at a temperature below 300 ° C. Metal, hydrides and metal nitrides in the powdered state can as catalysts for the fixation of nitrogen, and more particularly in the synthesis of ammonium as well as without pressure or under low pressure and low temperature. We produce chromium ortec by electrolytic method, which we intend to nitrate. We distill the Ortec in a vacuum and we obtain the chromium in a powdered state. Ortec can also be distilled in nitrogen, and then we get chromium nitride directly. PL
