Twin‐roller quenching produced wide ranges of glass formation in the systems Li 2 O‐RO‐Nb 2 O 5 (R=Ba,Ca,Mg). The glass‐forming ability is improved with an increase in the ionic radius of R 2+ ions. The crystallization temperature is increased as Li 2 O is replaced by RO or the ionic radius of R 2+ ions is increased. Infrared spectra revealed that the glass LiNbO 3 (=50Li 2 O‐0Nb 2 O 5 ) was composed of six‐coordinated NbO 6 octahedra, which were joined together by corner‐sharing only. In the Li 2 O‐RO‐Nb 2 O 5 glasses there exist edge‐shared as well as corner‐shared NbO 6 octahedra. The edge‐shared NbO 6 octahedra in the glasses are increased with an increase in the content of RO or Nb 2 O 5 , and also with an increase in the ionic radius of R 2+ ions.
