[en] Research on the influence of poly vinil alcohol and temperatures on theresulted sol solutions. The sols were fed into gelation process using ammoniamedium and resulted were (NH4)2U2O7 gels spherical. The PVA variablesaddition on the sol process were 10; 15; 20; 25 and 30 g/1l uranyl nitrates.The temperature variables on the sol process were 75, 80, 85, 90 and 95 oC.The sol which successfully resulted (NH4)2U2O7 gel the gelation processwas on the PVA amount of 15 g and 90 oC. The resulted gel was then washed,dried and calcinate. The characterization of shape and surface of gel havebeen carried out using SEM photography. The density of gels were measured.For the 15 g PVA addition, the density was 8.3710 g/ml. While for process at90 oC, the density was 7.8871 g/ml. (author)
