Abstract

У заявці описаний одержаний полуменевим гідролізом порошкоподібний діоксид титану, який знаходиться у вигляді агрегатів первинних частинок і має площу поверхні БЕТ, що дорівнює від 20 до 200 м2/г, напівширину (НШ) [нм] розподілу первинних частинок, НШ [нм]=а EMBED Equation.3 БЕТf, де а=670 EMBED Equation.3 10-9м3/г та -1,3 EMBED Equation.3 f EMBED Equation.3 -1,0, і частку частинок, які мають діаметр, більший за 45 мкм, що знаходиться в діапазоні від 0,0001 до 0,05 мас.%. Порошок одержують способом, у якому галогенід титану випарюють при температурі нижче 200°С, пару подають у камеру змішування за допомогою газу-носія, який має задану вологість, і незалежно від цього водень, первинне повітря, яке необов’язково може бути збагачене киснем і/або попередньо підігріте, і пару подають у камеру змішування, потім реакційну суміш спалюють у реакційній камері, яка захищена від доступу повітря навколишнього середовища, у реакційну камеру додатково подають вторинне повітря, після чого тверду речовину відокремлюють від газоподібних речовин, і потім тверду речовину обробляють парою. Цей порошкоподібний діоксид титану можна застосовувати для термостабілізації полімерів.
