China Amorphous Boron powder 0.8um 0.6um 95-96% B powder
China amorphous boron powder 0.6 μm and 0.8 μm ultra fine powder, is an efficient neutron-absorbing filler for radiation shielding materials. The purity of Amorphous boron range from 95-99.9%. The regular type is 95-96% for exporting. Amorphous boron features high boron-10 content and excellent thermal neutron capture capacity, delivering reliable shielding performance.
The fine particle size ensures good dispersion in polymer, resin or composite matrix, helping form uniform shielding structures.It has stable chemical properties, low impurity levels and will not easily degrade under normal service conditions. Amorphous boron powder is widely used for nuclear shielding boards, radiation protective coatings and nuclear industry composite shielding parts.

FAQ:
1. Q: Is there any restriction about export amorphous boron powder from China?
A: Yes, for Boron content above 97% of amorphous powder , it need to get dual-use export licence.
2. Q：What about the normal partilce size of amorphous boron powder ?
A：Regular size is with D50 size 1-3um. We can also supply smaller size such as 800nm 600nm and larger size such as 4um,5um, but price will be higehr.
