Refined Powder
型号：BNNT SP10-R-PBNNT "R-P" designation indicates "refined powder" for which the cotton-like network of as-grown SP10 has been broken up to a great extent and the boron nitride nanotubes provided are in powdered form. For some applications, SP10-R-P may be easier to disperse into solvents or other matrices in powdered form.
