    Effect of additions of zinc stearate on the properties of sintered Nd-Fe-B magnets

    Zinc stearate additions have been used to increase the remanence of sintered Nd-Fe-B magnets produced by the powder metallurgy without powder pressing. Zinc stearate acts as an internal lubricant, i.e., it dec...

    The mechanism of nitrite formation in the radiation-induced oxidation of ammonia in aerated aqueous solutions

    The mechanism of the radiation-induced conversion of ammonia to nitrites and nitrates in aerated aqueous solutions has been studied. The formation of the pernitrite ion, O=N-O-O−, was detected at pH ≥ 10.5. The k...

    A study by pulse radiolysis of the radiation-chemical transformation of aqueous solutions of hydrazine in the presence of oxygen

    It is shown by pulse radiolysis that in aqueous solutions of hydrazine containing oxygen the radical N2H3 reduces oxygen to O2 − at pH > 7 (k ≥3·109 dm3· mole−1·sec−1), while this reaction does not occur for the ...

    Radiochemical oxidation of hydrazine in aqueous solutions containing oxygen

    The chain mechanism of oxidation of hydrazine in aqueous solutions saturated with oxygen at pH > 7.5 was established. The yields of radiochemical decomposition of hydrazine increase with a decrease in the abso...
