In order to improve the safety and energy exchange efficiency of electric thermal pyrotechnic devices. a new energy exchange element technology of high energy metal (W) film/aluminum nitride ceramic was explored by taking advantage of the high thermal conductivity of aluminum nitride ceramic materials. High-temperature co-fired ceramics were used to prepare the new system energy excha... https://www.spidertattooz.com/The-GelBottle-Inc-Gel-Polish-Audrey-67oz-p17921/
