The gelation of hydrazine nitrate-hydrazine hydrate double components is studied. Sorts of gelling agents and the appropriate addition of gelling agents for the system in which the ratio of hydrazine nitrate and hydrazine hydrate is from 60∶40 to 70∶30 are given: HPAM 0.8%、guar gum 1.2%、CMCNa 1.8%. The ratio of absorbing moisture and TG analysis of gelled samples are tested.
