Очистка гафнію від кисню та азоту
Ключові слова:
гафній, реактор, рафінування, домішки, властивості
Анотація
В роботі приведені дані щодо впливу вмісту домішок проникнення на механічні властивості гафнію. Виконано дослідження з очищення гафнію від кисню при введенні алюмінію на стадії відновлювальної плавки з подальшою електронно-променевою плавкою. Показано, що вакуумтермічна обробка тетрафториду гафнію перед проведенням відновлювальної плавки забезпечує зниження вмісту азоту в гафнії менше 0,005 мас.%.
