Abstract
Изобретение относится к области получения абразивных материалов на основе борсодержащих соединений, в частности к нитриду бора аморфной структуры и способу его получения. Сущность изобретения: объектом изобретения является нитрид бор аморфной структуры, содержащий продукты реакции нитрида бора и ингибиторов кристаллизации, включенные в кристаллическую решетку нитрида бора с образованием аморфной по электронно-лучевому и рентгеновскому спектрам структуры. Другим объектом изобретения является способ получения нитрида бора аморфной структуры путем термообработки гексагонального или турбостратного нитрида бора при минимальной температуре 1650°С и минимальном давлении 70 кбар до полного расплавления сырья, охлаждения получаемого расплава путем прекращения подачи тепла и последующего сброса давления, при этом термообработку осуществляют в присутствии по меньшей мере одного ингибитора кристаллизации.
