Rdx heat of combustion
WebDec 17, 2024 · In view of this, we have to replace thiourea as a source of sulfur by elemental sulfur. Accordingly, the combustion of the optimized green composition 45% RDX–20% Ni(NO 3) 2 ·6H 2 O–20% S–15% HMDI was found to proceed with U = 0.14 mm/s and T max = 925 K. In this case, combustion product appeared as a clotted powder with s = 68 m 2 … The substance's toxicity has been studied for many years. RDX has caused convulsions (seizures) in military field personnel ingesting it, and in munition workers inhaling its dust during manufacture. At least one fatality was attributed to RDX toxicity in a European munitions manufacturing plant. During the Vietnam War, at least 40 American soldiers were hospitalized with composition C-4 (w…
