Hexachlorobenzene has not been manufactured in the United States (as an end-product) since its last registered use as a pesticide was voluntarily canceled in 1984. Small amounts of hexachlorobenzene are still released to the environment by industrial activities as fugitive and stack emissions, or in waste water. It is released as a by-product during the manufacture of several chlorinated solven...

This paper presents research on the development of pyrotechnic compositions producing an acoustic effect. These types are used in firecrackers to imitate a cannon shot—they most frequently during military exercises. The was based mathematical model experiment. For environmental reasons, replacement harmful oxidant Ba(NO3)2 by KClO4 and NH4ClO4 modelled. were tested for reliability evaluated ter...

Creating next-generation pyrotechnic emitters capable of dynamically controllable light output requires a paradigm shift away from emission control via formulation. This work demonstrates the ability to modulate intensity flame with 2.46 GHz microwave energy within multimodal cavity. Stoichiometric mixtures three systems are investigated: magnesium fuel oxidizers NaNO3, KNO3, or CsNO3. Using ti...

It has been shown that defect-free Stone–Wales (SW) free few-layer graphene (FLG) can be obtained by carbonizing lignin under conditions of self-propagating high-temperature synthesis (SHS). The was used as a modifying additive for pyrotechnic compositions. found the addition 2.5 mass % synthesized from to complex based on porous silicon and fluoropolymer leads significant increase in combustio...

Perchlorates are high melting point inorganic salts that are soluble in water. There are five perchlorate salts that are manufactured in substantial amounts: magnesium, potassium, ammonium, sodium, and lithium perchlorate. Perchlorates are powerful oxidizing agents and at elevated temperatures, they can react explosively. The production volume of ammonium perchlorate far outpaces the other salt...

Abstract In order to meet the application requirements of high performance, safety and reliability laser explosives in future weapons equipment, this paper tries solve problem interaction between energetic materials, studies law fiber materials with beam quality. The principle prototype all-fiber ignition quality is developed. pulsed was studied. Fast efficient based on realized. Compared semic...
