Description

technical field [0001] The invention belongs to the technical field of solid propellants, and in particular relates to a class of dinuclear ferrocenetriazole ionic metal complexes and a preparation method thereof. Background technique [0002] The dual-nuclear ferrocene burning rate catalyst has gradually replaced the mononuclear ferrocene burning rate catalyst due to its advantages of high iron content, excellent burning rate catalytic effect, high boiling point, good thermal stability, low volatility, and low mobility. . However, although the dual-nuclear ferrocene-based burning rate catalyst has excellent comprehensive performance, it is easy to oxidize, contains no energy, crystallizes at low temperature, and has a complicated synthesis process, which seriously affects the storage life and reliability of various missile propellant charges in our country. It also greatly increases the expenditure on national defense scientific research. Therefore, scientific researchers...
