Sep 6, 2018 - X-Ray Diffraction analysis has confirmed the HPA as the desired alpha (α) ... Confirmation of 4N (99.99%) High Purity Alumina (HPA) ... also been analysed by X-Ray Diffraction (XRD) which confirmed that the HPA is 100%.

now asking the question
is KRR chasing the 4N level 99.99%
or the super valuable 5N level at 99.999%
?

for the average joe, some one claims 100% but that 100 it only 99.99% but is still 100%
now thats surely a little tricky for 99.99% of the population
