Content
Opening
Tetrafluorohydrazine was first obtained by Colburn and Kennedy.
Getting
An industrial method of obtaining is the interaction of nitrogen trifluoride with fine chips and waste from stainless steel, copper, arsenic , antimony or bismuth . After receipt, it is purified by distillation.
Application
The use of tetrafluorohydrazine allows you to get a large specific impulse of the rocket and dramatically increase its range and speed. One of the most important properties of tetrafluorohydrazine is its high density and cooling ability when operating a rocket engine.
