“…With the development of information technology, micro-electromechanical system (MEMS) technology, new energy, new materials and other high-tech technologies, the fourth generation of initiating explosive device—MEMS-initiating explosive device, with the advantages of miniaturization, integration, multi-function, high precision and high reliability—has made great progress, which has a new requirement for dynamic measurement of the ignition temperature of initiating explosive devices [ 1 , 2 ]. The ignition temperature is an important index of the safety and performance of the explosive device, and the test and determination of the ignition point is an important basis for the reliability design, appraisal and evaluation of the explosive device [ 3 , 4 , 5 ].…”

Aiming at the dynamic testing of the ignition temperature of micro-initiating explosives, a novel Pt-Rh10/Pt thin-film thermocouple was designed in this paper. The author carried out the preparation of the thermocouple by using a screen printing process on an Al2O3 ceramic substrate. The formed thermocouple was made of Pt-Rh10 wire and Pt wire as compensation wires, with a size of ≤ 1 mm and a thickness of about 6 μm. In the testing process, the static calibration of the thermocouple at 50~600 °C and 650~1500 °C was completed by a portable temperature verification furnace and a horizontal high temperature verification furnace, and the results showed that the Seebeck coefficient of the thermocouple was about 10.70 μV/°C, and its output voltage–temperature curve was similar to that of a standard S-type thermocouple, which achieved the effective temperature measurement up to 1500 °C. The dynamic response of Pt-Rh10/Pt thin-film thermocouple was then tested and studied using the pulsed laser method, and the results show that the time constant of the thermocouple prepared in this paper is about 535 μs, which has the characteristics of fast response and high precision high-temperature testing. Compared with the traditional thin-film thermocouple, the thermocouple has excellent electrical conductivity, more oxidation resistance, the surface layer is not easy to peel off and other advantages.

“…Analysis of the freely available information shows that two main applications of the considered ESCs are consid: replacement of initiating explosives (IE) in detonation means [4] and creation of pyrotechnic compositions for ignition means [5]. It can be noted that, in addition to ESCs based on porous silicon, ESCs based on boron, boron compounds, titanium borides, aluminum, etc.…”

Optical and electron-beam initiation of porous silicon films with different contents of oxidizer and graphene

et al. 2022

Laser and electron-beam initiation of the combustion process of energy-saturated composite films were studied. Composites were produced from porous silicon, a fluorine-containing polymer, and graphene. It is shown that the impact of a high-current electron beam of nanosecond duration does not lead to the excitation of the combustion process. Moreover, the process of film combustion during laser initiation is accompanied in some cases by the appearance of a zone of secondary flame and white smoke. Keywords: porous silicon, energy-saturated composite, laser initiation, electron-beam initiation, combustion.
