Melt Crystallization of Ammonium Dinitramide (ADN) Investigated by Means of X‐ray Diffraction
نویسندگان
چکیده
Ammonium dinitramide (ADN) is a promising oxidizing agent for solid rocket propellants. In situ XRD investigations of ADN and suspensions have been performed in order to understand refine the emulsion crystallization process manufacturing spherical particles (prills). The investigation revealed that melt behavior depends on quality, humidity, maximum temperature cycles, suspension agents. Further will focus additives controlling mechanisms investigated, e.g., by seeding.

Synthesis of Ammonium Dinitramide by Nitration of Potassium and Ammonium Sulfamate. The Effect of Sulfamate Conterion on ADN Purity
Nitration of potassium sulphamate was carried out using a mixture of sulphuric and nitric acid at -30 °C. The reaction time was optimized at the mole ratio of sulphuric to nitric acid of (1:3.5). The difference in product yield by changing the potassium to ammonium sulphamate was studied throughly. It was found that both the yield and purity of the product is better starting with potassium ...

Isothermal melt crystallization kinetics of PVDF was investigated by differential scanning calorimetry. Thin PVDF film has been fabricated by the solvent casting technique using dimethylformamide (DMF). Then, the samples were melted and subsequently crystallized in the range of the crystallization temperature (Tc) between 138 and 145 °C. The crystallization kinetics was derived from Avrami equa...
