Taconite is one of the important type of rocks. If we have to define Taconite in general, Taconite is a low-grade iron ore which belongs to sedimentary rock and containing about 27% iron and 51% silica. Taconite comes under Sedimentary Rocks. All Sedimentary Rocks have similar properties and formation process.

Polycrystalline diamond (PCD) has been extensively explored as a radiation detector, particularly to exploit its radiation hardness as, for example, in large detector assemblies (Adam et al., 2000) where the inhospitable environment does not permit conventional materials to survive for the periods desired.Diamond – PCD or CVD? - Telcon,CVD Diamond coating: Hardness: PCD is a composite diamond, 90-95% diamond powder + cobalt binder, therefore lower hardness than CVD. Around 6000 Vickers hardness. CVD is 99% pure diamond, therefore hardness is the highest. Around 8500 Vickers hardness. Wear resistance: Since PCD contains cobalt, the edge is more likely to wear faster, but that occurs until a certain edge radiusAsha Vs Nexus Diamond Simulant Comparison,It has a hardness of 9.1 compared to CZ’s hardness, which is an 8.5 on the Mohs scale.
