Summary

  1. 1.

    We have synthesized solid solutions in the systems Ce2O3·2SiO2-Nd2O3·2SiO2 and Ce2O3·2SiO2-La2O3·2SiO2.

  2. 2.

    We have found the temperature limits for the existence of limited solid solutions (xCe2O3·2SiO2, yLn2O3 ·2SiO2) in an oxidizing atmosphere (in air). In a reducing atmosphere (H2, CO) continuous solid solutions form in these systems.

  3. 3.

    We have synthesized the oxyorthosilicate of cerium Ce2O3·SiO2 in a reducing atmosphere and its solid solution with oxyorthosilicates of rare earths of the lanthanum subgroup and calcium of composition: [(0.5 Ce, 0.2 La, 0.2 Nd, 0.1 Pr)2O3·SiO2 (3CaO·SiO2)].

  4. 4.

    In the synthetic ceftosil mineral cerium is in the trivalent state.
