We found a new technique to synthesize diamond nanopowders through the decomposition of
graphitic [C.sub.3][N.sub.4] under HPHT.
This hole was terminated as a precautionary measure as it intersected the same pronounced
graphitic kaolinised shear that caused the drilling problems in hole CSDD12_003.
In the case of very small nanoparticles one can observe superparamagnetic behaviour, related to the demagnetization effect arising from the additional energy of the magnetic fields outside the
graphitic carbon encapsulation.
At Campoona Shaft the arithmetic average of the
graphitic schist in the 10 holes completed to date (sample size n=267; xi 11.0%TGC) is 10-12%TGC.
For hypoeutectic
graphitic irons, the CFS should be set just past the start of the eutectic zone.
Drilling results at Campoona Shaft confirm that the graphitic-rich body consists of a discrete intense
graphitic shear zone hosted in low grade
graphitic proto-gneiss (high grade metamorphosed sediments).
The results show the continued performance of the Campoona
graphitic schist structure.
Completed as an undercutting step-out drill hole 200m east of the LE19-22/KER-07 section, drill hole LE19-26 intersected impressive sandstone faulting, alteration, and elevated radioactivity in the basal sandstone and strongly faulted
graphitic gneiss in the basement rocks.
Notably, abundant at-surface graphite minerlisation has been identified over a 1-kilometre strike length with graphite grading up to 4.93% total
graphitic content (TGC).
The natural resources investor said that initial metallurgical test work results from the flotations stage reveal solid graphite recovery up to 95% of total
graphitic content, consistent with company expectations.
The profile shows two peaks at 2I, of 23.85Adeg and 26.55Adeg (with interlayer spacing 3.73A and 3.36A calculated according to the Bragg's equation) corresponding to the amorphous and the
graphitic nature of the resulted product (JCPDS Code: 00-008-0415) as also described earlier in the literature [14, 17-24].
