Abstract: The interior and surface structures of sample A,B,and C were characterized by X-ray power diffractometer and infrared diffuse reflection spectrum.The results showed that the interior of sample A was MgO with slight Mg(OH)2 at the surface.By contrast,both the interior and surface of sample B and C were composed of MgO and Mg(OH)2,and the relative quantity of Mg(OH)2 in sample B was larger than that in sample C.The thermal decomposition properties of sample A,B,and C as well as their mixtures with nitrocellulose (NC) were examined by differential scanning calorimetry.The results revealed that there was no melting peak in sample A/NC,and the heat adsorption capacity of sample B/NC was bigger than that of sample C/NC.The combustion performances of MgO based propellant a,b,and c prepared by A,B,and C,respectively,were tested.The propellant b had the optimal combustion performance,which can be attributed to the high quantity of Mg(OH)2 in B,suggestive of stabilization effect of Mg(OH)2 on burning rate.
