Hydroxypropyl methylcellulose is a water-soluble polymer compound, also known as water-soluble resin or water-soluble polymer. It increases the consistency of the mixture by increasing the viscosity of the mixing water. It is a hydrophilic polymer ma
In addition to studying the ignition and combustion mechanism of boron particles, surface modification strategies are beneficial to improving the combustion efficiency of boron powder. Surface modifications of boron powder can improve surface properties and increase the energy and reactivity of energetic systems. Energetic materials can release a considerable amount of heat during combustion, improving the surface temperature and boron's ignition and combustion properties. The energetic material
Silicon nitride ceramics is a synthetic material. In its structure, the covalent bond between silicon atoms and nitrogen atoms is strong. Therefore, silicon nitride ceramics have high strength, high hardness, corrosion resistance, oxidation resistance, an
