Thixotropic gels are also useful as propellants for rocket applications. These are commonly called thixotropes or gels. Normal fuels and oxidizers are converted into thioxotropes by the addition of a small quantity of a gelling agent in order to ensure uniform suspension of solid additives (usually metal additives) during storage. It is reported that if very finely pulverized particles of beryllium or aluminum are suspended in the liquid fuel, it is possible to increase the specific impulse substantially. 

In rocket technology the name for liquid or gelled homogeneous propellants, which require no other reaction partner for the formation of gaseous reaction products. Gas formation can be due to catalytic decomposition (on concentrated H202 or anhydrous hydrazine) or to an intramolecular reaction, e.g., by decomposition of propylnitrate generating N2, CO, CO2, NO, etc., -> Liquid Propellants.
