FAQ:
Q: What is the tested value of Boron content of 95% Amorphous B powder?
A：The garantee value of 95% Amorphous B powder is min 95%, typical value is 95.5-95.7%.
Q：Is there any restriction about Amorphous boron powder export from China?
A: Yes, Boron content above 97% is not allowed to export from China. It need to get dual-use export licenece.
Q：What is the particle size of amorphous boron powder you can produce?
A：The ordinary D50 size of amorphous boron powder from us is 1-3um. For larger size such as 4um,5um and smaller size such as 800nm,500nm, it need to make extra treatment.
Generally, the particle size of amorphous boron powder is not bigger than 10um.
