Amorphous boron powder B powder from China无定形硼粉厂家
Amorphous boron powder is amorphous high-purity boron powder with an excellent thermal neutron absorption cross-section and outstanding neutron capture efficiency. Compared with crystalline boron, it has higher reactivity, better powder dispersibility, and is easy to composite with various matrices. The product has low heavy metal impurity content and can be stably used in neutron absorbing components such as nuclear radiation shielding and reactor control materials. It is suitable for the preparation of boron-aluminum alloys and boron-based composite materials and is a key raw material for high-performance neutron absorbing materials.
无定形元素硼粉为非晶态高纯硼粉体，具备优异的热中子吸收截面，中子捕获效率突出。相较于结晶硼，其反应活性更高，粉体分散性好，易于与各类基体复合成型。产品重金属杂质含量低，可稳定用于核辐射屏蔽、反应堆控制材料等中子吸收构件。适用于硼铝合金、硼基复合材料制备，是高性能中子吸收材料关键原料。
