PREFACE
Thisbookpresentsreviewsoftheresultsofstudyingthetransformationsinnanoenergetic
materials.Thetermnanoenergeticmaterialsisusedheretocharacterizetheenergeticmate-
rialsorenergeticsystems,containingorconsistingofnanocomponents.Thisisarelatively
young but very promising field of research, and expected results could lead to break-
throughs in the development of advanced explosives, propellants, and microenergetic
devices. Common advantages of nanoenergetic materials are their great reactivity and
ability of very fast chemical transformations.
From the beginning, the most developed nanoenergetic materials were based on
nanometals.Thosematerialsareproducednowbydifferentmethodsinseveralcountries
and their production reached a relative maturity. Another direction of research is based
onstudyingthenano-oxides,whichhavefoundwideapplicationascatalystsinsolidpro-
pellants as well as in pyrotechnic compositions. Those compositions may demonstrate
extremely high combustion propagation rates comprising few km/s. Energetic nano-
composites can find also wide application in mini rocket motors and in different types
of microchips.
Evidently,efficientrealizationofuniquepropertiesofenergeticnanomaterialscanbe
performed only based on studying the intrinsic mechanisms of the reactions in solids at
theatomisticlevel.Toacquiresuchknowledge,oneneedstoexplorethosemechanisms
with use of advanced techniques and sophisticated approaches. Intense work in this
direction is underway in many countries.
This book summarizes the recent achievements (since w2005) of the leading scien-
tific groups working in the field of energetic nanomaterials in China, Germany, Israel,
Italy, Russia, and the United States.
Chapter1presentsacomprehensivereviewofthemodernachievementsinnanoma-
terialssynthesisandapplication,emphasizingthattheresearchinnanochemistryopeneda
bottom-up approach in the architecture of matter on a different spatial scale. This
approach may provide effective tools for understanding the mechanisms governing the
nanoenergeticmaterialsproperties,whichwouldallowcreatingnewenergeticsubstances
with well-tailored chemical and physical properties.

The characteristics of coating aluminum particles by nanometric layers of nickel or
iron are considered in Chapter 6. Coated particles ignite at a much lower temperature
and exhibit shorter ignition times than uncoated ones due to exothermic intermetallic

The characteristics of gasless metalenonmetal and metalemetal nanostructured
composite particles, prepared by high-energy ball milling, as well as of thermite-like
metalemetal oxide mixtures of nanopowders are discussed in Chapter 8. Those reac-
tive systems demonstrate extremely low ignition temperatures and very high reaction
frontpropagation velocitiesthatcanbeas highas103m/s.Efforts are made toexplain
the observed phenomena.
The catalytic effect of nano-oxides of Ti, Al, Fe, and Si on HMX thermolysis and
combustion is discussed in Chapter 9. The point defects in the catalyst material are
considered in the interfacial catalysis mechanism and it is shown that the presence of

The characteristics of oxide nanoparticles formed in combustion of aluminum and
titanium microparticles are discussed in Chapter 11. Despite the distinctions in the
mechanism of aluminum and titanium combustion, their oxide nanoparticles are of
almost the same dimensions and display similar morphological and charge properties.
The charging of metal nanoparticles due to thermoelectron emission plays a key role

andsomeunresolvedproblemsinstudyingthemechanismofnanoparticlesgrowthare

Chapter 12 summarizes the recent efforts to incorporate the benefits of nanoscale
materials to propellants without the drawbacks due to sintering the nanoparticles and
increasing the viscosity of propellant slurry. One of the effective approaches is encapsu-
lation of nanoscale materials into crystalline particles that for nanoscale catalysts show
improved performance over direct physical mixing. Another approach is encapsulating
the inclusion materials into metals, like aluminum, that may facilitate the ignition of
metalparticlesandformationofsmallersizecombustionproductssincetheparticlesfrag-
ment when heated.
Chapter 13 describes the advanced techniques and approaches for precharacteriza-
tionofnanoparticlesofAlusedincondensedenergeticsystems.Differentpropertiesof
various powders (passivated by air or organic compounds and coated by hydrocarbons
and fluorohydrocarbons) are investigated. The presented results provide some insight
into the relationships between nanosized additives’ morphology/structure, oxidative
reactivity, and propellant/fuel rheological behavior.
Each chapter was carefully edited according to the procedures employedby archival
publications. Thus, the book can be considered as supplemental reading for students,
researchers, and engineers in research centers and in industries dealing with energetic
materials production, characterization, and applications.
