    Abstract: Stable suspensions useful as high energy propellant and agricultural compositions comprising a finely-divided vehicleinsoluble organic or inorganic powder, 0.2 to 3.0 percent vehicle-insoluble microfibers and a liquid vehicle which is either a liquid hydrocarbon or a hydrocarbon soluble polar hydrocarbon derivative such as an amine, amide, ketone, alcohol, etc. The microfibers are either inorganic microfibers having an average particle between 0.01 and 2.0 microns or organic microfibers having an average fiber diameter between 1 and 20 microns. A typical stable suspension comprises 68.72 percent aluminum powder, 1.43 percent diethyl stearyl amide, 0.75 percent glass microfibers having an average fiber diameter of 0.05 to 0.2 microns and 29.1 percent kerosene. This stable suspension useful as a propellant was prepared by blending glass microfibers into the kerosene fraction to form a soft gel and separately blending the aluminum powder with distearyl amide; the aluminum-amide mixture is then slowly added to the glass fiber-kerosene gel until a buttery suspension is formed.

    Abstract translation: 稳定悬浮液可用作高能推进剂和农业组合物，其包含细分的载体不溶性有机或无机粉末，0.2-3.0％不溶于载体的微纤维和液体载体，其为液体烃或烃溶性极性烃衍生物，例如 胺，酰胺，酮，醇等。微纤维是平均粒子在0.01和2.0微米之间的无机微纤维或平均纤维直径在1和20微米之间的有机微纤维。 典型的稳定悬浮液包含68.72％的铝粉，1.43％的二乙基硬脂酰胺，0.75％的平均纤维直径为0.05-0.2微米的玻璃微纤维和29.1％的煤油。 通过将玻璃微纤维混合到煤油馏分中以形成软凝胶并将铝粉末与二硬脂酰胺分开混合来制备用作推进剂的该稳定悬浮液; 然后将铝 - 酰胺混合物缓慢加入到玻璃纤维 - 煤油凝胶中直到形成黄油悬浮液。
