Abstract : Two sets of experiments on the recently purchased batch of GE synthetic diamond power obtained from Dubbledee Harris Diamond Corporation are scheduled for this month. Powders of controlled particle size distribution have been acquired to yield maximum initial packing densities (70%). The powders have been treated at 800 deg C in argon atmosphere, similar to previous heat- treatments. Fluorinated diamond powders, and diamond powders mixed with approx. 10% melamine formaldehyde copolymer will also be tested in these experiments. We continue to analyze the previous shock compacted diamond samples, via Raman, X- ray diffraction, and electrical resistivity. Based on these tests, several other samples have been isolated to send to CalTech for thermal conductivity measurements.
