Abstract

The invention provides a molybdenum compound-loaded boron fuel and an ion exchange method preparation method, the method adopts an ion exchange method to load molybdenum compound particles or films on the surface of boron powder to form the molybdenum compound-loaded boron fuel; the ion exchange method comprises the following steps: by taking molybdenum salt as a molybdenum source, carrying out ion exchange on the molybdenum source and the surface of boron powder to obtain an exchange intermediate product, and heating the exchange intermediate product at high temperature to prepare the boron fuel loaded with the molybdenum compound. The content of the molybdenum compound in the boron fuel loaded with the molybdenum compound is 0.1 wt.%-10 wt.%. The prepared molybdenum compound / B can provide more molybdenum compound-B active interfaces, the oxidation process of boron powder can be obviously catalyzed even if the content of the molybdenum compound is low, and the activity is high.

Description

technical field [0001] The invention belongs to the technical field of high-energy solid propellants, relates to boron fuel, and in particular relates to a highly active boron fuel loaded with molybdenum compounds and a preparation method by an ion exchange method. Background technique [0002] Adding high calorific value metal fuels to energetic material systems has become the most common and effective method to improve the energy output of energetic materials. Aluminum and magnesium are the most commonly used metals with higher calorific value in energetic materials, while the calorific value of boron is superior to that of magnesium and aluminum. The mass calorific value of boron is 58.74MJ / kg (2.3 times that of aluminum and 1.9 times that of magnesium), and the volume calorific value is 135.24kJ / cm 3 (3.1 times that of aluminum and 1.6 times that of magnesium), so boron is an ideal energetic material additive. Boron-based fuel-rich propellants have high energy release ...
