Ключові слова:

детонацiйнi наноалмази, пористiсть, фрактальнi кластери, високий тиск, малокутове розсiяння нейтронiв, рентгеноструктурний аналiз

Анотація

Алмазнi наночастинки мають значнi перспективи технологiчних застосувань, тому їх виготовлення та подальша деагрегацiя є актуальною задачею. В данiй статтi за допомогою малокутового розсiяння нейтронiв проаналiзовано пористу структуру агрегатiв у порошках детонацiйних наноалмазiв. Вплив високого тиску дозволив роздiлити внески у малокутове розсiяння вiд мiкро- та нанорозмiрних пор. Визначено тип фрактальних кластерiв, утворених нанопорами. Пiдтверджено можливiсть часткової механiчної деагрегацiї наноалмазних частинок за тиску 1,5 ГПа.
