Boron Ribbon,CAS RN: 7440-42-8
Product Code : EB-A240-CU-CU
HANG JI specializes in producing high purity Boron Ribbon,CAS*: 7440-42-8 with the smallest possible average grain sizes,Purities may include 99%, 99.9%, 99.99%, 99.999% and 99.9999%, which are sometimes referred to as 2N, 3N, 4N, 5N and 6N,6N5, and in some cases up to 99.99999% (7N),99.999999% (8N),HANG JI produces to many standard grades when applicable, including Mil Spec (military grade); ACS, Reagent and Technical Grade; Food, Agricultural and Pharmaceutical Grade; Optical Grade, USP and EP/BP (European Pharmacopoeia/British Pharmacopoeia) and follows applicable ASTM testing standards. Typical and custom packaging is available. Our standard powder particle sizes average in the range of - 325 mesh, - 200 mesh,- 100 mesh, 10-50 microns and submicron ( 1 micron). We can also provide in the nanoscale range.Powders are also useful in any application where high surface areas are desired such as water treatment and in fuel cell and solar applications. Nanoparticles also produce very high surface areas .Quality inspection department staff which uses atomic spectroscopy, x-ray diffraction analysis, scanning electron microscopy, glow discharge mass spectroscopy (GDMS), and BET surface area analysis, among other technologies, to ensure that the elemental composition and structural properties of each product rigorously adhere to our standards.Additional technical, research and safety (MSDS) information is available,
