An alternative fine grade of the NCM831205 composition at 3.0 microns. At 18.24 m²/g it has the highest surface area for this composition; the increased surface area multiplies contact points with the lithium source and raises reaction rate. Together with Grade A it allows the effect of surface area on synthesis to be examined.
