Nanofiber SiC (~50nm grain size)/PAN was prepared at UBC. 

SiC 0.50g, DMF 9.0g, PAN 1.0g, tiny bit of SDS.

The fiber mat was stabilized in air at 250C and then cut into discs, initial mass = 0.1072g

Discs were then bounded with PVA on 9 pieces of rounded graphite foil  (green mass gained to 0.6031g)

The stack of naofiber SiC/PAN was loaded on to Ta boated (coated) and wrapped with Ta heat shield. 

Chamber is currently being pumped down.
