HEP
High-Energy Powders (HEP):
composite granules combining two or more components capable of exothermic (with energy release) or endothermic (with energy absorption) interaction between its components.
Energy-producing HEP (VHEP) are created for development of::
- out-of-furnace technology of local energy release;
- autonomous anaerobic heating systems with thermal or deformation initiation;
- autonomous anaerobic lighting systems;
- Autonomous life support systems in emergency conditions (anaerobic heating and light alarm).
Energy-absorbing HEP (PHEP) are created for the development of:
- heat-resistant and fire-resistant polymers, paints and coatings;
- highly efficient fire extinguishing systems;
- technological processes with local energy absorption;
- energy-absorbing materials.
ABOUT THE PROJECT
HEP are obtained by mechanical activation of a mixture of metal powders and compounds capable of the necessary chemical reactions.
Mechanical activation provides the maximum contact area of the components to ensure a high rate of chemical interaction in the solid phase.
Chemical interaction of components in the process of mechanical activation is absent.
In the manufacture of VHEP granules, they are saturated with an ultra-high number of defects in the crystal structure, the relaxation of which takes place at high speed with the release of heat.
In the manufacture of PHEP granules, relaxation of crystal structure defects that arose during mechanical activation is carried out.
VHEP include various options for exothermic chemical reactions with high energy effect.
Reactive components of VHEP have a large contact area, which determines the possibility of interaction in the chain mode of thermal explosion.
VHEP are saturated with an ultra-high number of crystal structure defects, the relaxation of which also passes at a high rate with the release of heat.
VHEP after local initiation is capable of self-heating to temperatures from several hundred to several thousand degrees Celsius.
In VHEP with a minimum power and self-heating to temperatures (300-600) °C is the implementation of SHS process (self-propagating high-temperature synthesis) in the solid phase.
In VHEP with average power and self – heating to temperatures (700-1500) °C is the implementation of SHS process with the formation of the liquid phase.
In the VHEP with maximum power and self-heating to temperatures above 5000°C, the SSS process (Solid – Steam – Solid) is implemented with the evaporation of components and the formation of a gas plasmoid from dusty ionized plasma.
Project objective: development of high-performance technology for obtaining dispersion-strengthened composite materials with oxide reinforcement.
Consumers: developers, manufacturers and customers of innovative materials for GTD of new generation.
Technology: formation of a volume of disperse strengthened composite material with micron-and nano-sized reinforcing particles with the use of technology TPT process.
Main stages of the technological process:
Essence of innovation: formation of a mixture of components of the composite material in the transition of the components in pairs allow to achieve a unique connection at the interface and homogeneity of the distribution of components.
- New types of motors with vacuum – gas pressure – vacuum cycle operation;
- Heat treatment, including local treatment of one part at different temperatures;
- Technological processes of deformation with local heating to temperatures significantly higher than the heating temperature of parts in the furnace;
- Systems for local destruction of electronic media data;
- Autonomous anaerobic heating systems for life support in closed volumes (snow-covered cars on tracks in case of unexpected snowfalls, life support systems for miners, divers, climbers), premises of remote weather stations and observation posts, as well as in emergency conditions.
Various variants of endothermic chemical reactions with high energy effect or phase transition to a new aggregate state of one of the components are incorporated in PHEP.
Reactive components of PHEP have a large contact area, which determines the possibility of interaction with high speed.
PHEP do not have defects in the crystal structure, the relaxation of which takes place with the release of heat.
PHEP after heating to a critical temperature are capable of absorbing energy and thermal stabilization of the entire system, where they are located for a certain time.
A variant of spontaneous return to the initial state is possible when cooling PHEP with components having a reversible reaction.

- Development of heat-resistant polymers, paint systems and coatings that can withstand heating above a certain temperature for a certain time, both in a single and reusable operating cycle;
- Development of dry and hydraulic systems with PHEP for preemptive volumetric injection to reduce the temperature in the protected volume;
- Development of dry and hydraulic fire extinguishing systems with PHEP for fire control;
- Heat treatment, including local treatment of one part at different temperatures;
- Introduction of PHEP in pre-defined areas of polymers to prevent temperature-activated polymerization and to create the necessary configuration of the polymerized plastic product;
- Formation of zones of low ductility by means of local reduction of the temperature of certain areas of the work piece during the deformation;
- Thermal stabilization of the constructed objects due to volume introduction of the corresponding PHEP in construction materials.
- Creation of a new type of active energy-absorbing materials with the ability to absorb the energy of sound waves and moving objects under their influence on the barrier by triggering PHEP contained in these materials.
