tantalum oxide/ pentoxide

Ta2O5, Nb2O5 are white Powders,
We can produce different purities as follows:

Industrial grade purity : 99.6%
electronic grade purity : 99.8% or 99.9% maily for capacitors
optical grade purity: 99.99% maily for optical glass
single crystal level purity: 99.995% maily for lithium niobate/tantalate crystals

can provide assay report to analyze Impurities and mesh number / particle size.
