Abstract

resumo “aglomerados de nitreto de boro, método para a produção dos mesmos e uso dos mesmos” a invenção refere-se a aglomerados de nitreto de boro que compreendem partículas primárias de nitreto de boro hexagonal, sendo que as partículas primárias de nitreto de boro hexagonal são conectadas umas às outras por meio de uma fase de ligação inorgânica que compreende pelo menos um nitreto e/ou oxinitreto. a invenção também está relacionada a um método para produzir tais aglomerados de nitreto de boro, sendo que o pó de partida de nitreto de boro, sob a forma de partículas primárias de nitreto de boro, é misturado com a matéria-prima de fase de ligação, processado em grânulos ou corpos modelados e esses são, então, submetidos a um tratamento por temperatura a uma temperatura de pelo menos 1.000°c em uma atmosfera de nitretação e os grânulos ou corpos modelados obtidos são fragmentados e/ou fracionados se necessário. os aglomerados de nitreto de boro, de acordo com a invenção, são adequados como uma carga para os polímeros a serem usados para produzir os materiais compósitos de nitreto de boro-polímero.
