Abstract
- Abstract: Ammonium perchlorate(AP) and LiBH<subscript>4</subscript> can form an oxidation‐fuel energetic system, which provides a new development direction in designing novel mixed explosive formula. The microcalorimetry and self‐designed slow cook‐off setup were used to study thermal performance of AP/LiBH<subscript>4</subscript> energetic powders and grains respectively. Experimental results show that heat release in microcalorimetry method for the mixed system at low temperature was due to the reaction between LiBH<subscript>4</subscript> and residual water vapour. The oxidant gases from AP decomposition participate in the oxidation of LiBH<subscript>4</subscript> at high temperature. The ignition temperature for the AP/LiBH<subscript>4</subscript> grain was 270 °C and the explosion reactions were violent in slow cook‐off test. [ABSTRACT FROM AUTHOR]
