Razrabotka novykh superionnykh soedineniy i opticheskikh materialov yavlyaetsya vazhneyshim nauchnym napravleniem sovremennogo materialovedeniya, t.k. do sikh por sushchestvuyut problemy v tekhnologii polucheniya kompaktnykh i bezopasnykh litievykh akkumulyatorov i optimizatsii fotoprelomlyayushchikh i opticheskikh svoystv legirovannogo kristalla niobata litiya. V dannoy rabote izucheny zakonomernosti fazoobrazovaniya v troynoy sisteme Li2O-ZnO-Nb2O5 metodom secheniy v subsolidusnoy oblasti, a takzhe sintezirovany i kompleksno issledovany (opredeleny kristallograficheskie, termicheskie, spektroskopicheskie, opticheskie kharakteristiki i elektrofizicheskie svoystva) naydennykh faz v sistemakh Li2O-MO-Nb2O5 (gde M=Zn, Mg). Sintezirovany fazy Li6MNb4O14, LiMNb4O11.5, LiZnNb6O16.5. Opredeleny oblasti sushchestvovaniya perechislennykh faz, soderzhashchikh kation tsinka, i ikh termoustoychivost'. Fazy Li6MNb4O14 obladayut vysokoy ionnoy provodimost'yu. Fazy LiZnNb4O11.5 i LiZnNb6O16.5 mogut yavlyat'sya osnovoy dlya postroeniya struktur, obladayushchikh nelineyno-opticheskimi svoystvami. Rentgenograficheskie dannye po faze LiZnNb4O11.5 napravleny v poroshkovuyu bazu dannykh JCPDS PDF s vysshim znakom kachestva.
