The paper is concerned with the ternary compound Rb₂O.B₂O₃.4SiO₂ which is precipitated during crystallization of glasses of suitable compositions in the system Rb₂O-B₂O₃-SiO₂. This ternary phase analogous to boroleucite or leucite crystallizes in the cubic system with lattice parameter a = 12.78 x 10-10 m. |
