Abstract

Предложен поглощающий нейтроны композитный материал, содержащий гомогенную матрицу из первой компоненты, представляющей собой керамический материал, в котором гомогенно диспергированы скопления (сгустки) по крайней мере одной второй компоненты, выбираемой из тугоплавких металлов, боридов молибдена и ВС, причем по крайней мере одна из обеих компонент содержит бор. Предложен также способ получения композитного материала, в котором гомогенно смешивают порошок первой компоненты, имеющий среднюю гранулометрию ниже 5 мкм, со скоплениями (сгустками) второй компоненты (вторых компонент), и затем смесь уплотняют путем прокаливания под давлением в течение времени, достаточного для получения конечной плотности, по крайней мере равной 30% теоретической плотности.
