噴霧乾燥法による微粒な多孔質過塩素酸アンモニウムの調製

抄録

In general, a decrease in the particle size or an increase in the specific surface area of Ammonium Perchlorate (AP) results in an increase in the burning rate of AP composite propellant. Recently, it has become necessary to manufacture a propellant with a higher burning rate. In order to attain this requirement, fine porous AP is one of the possible candidates.
In the present work, an attempt was made to prepare fine porous AP by the spray-drying method. Consequently, fine porous AP was prepared. The mean diameter of these particles is 3.5μm, and their specific surface area is 2.12×10³m²/kg. It is proved that the spray-drying method is available for the preparation of fine porous AP.
