Nanofiber SiC (~50nm grain size)/PAN was prepared at UBC. 
SiC 0.50g, DMF 9.0g, PAN 1.0g, tiny bit of SDS.

The purpose of this experiment is to determined the limiting operating temperature for Beta-SiC.  To do so, samples will be heated in sequence
to observe any volatile Si coated on the window.  The coating is observed above 1400C for the conventional SiC (mixuture of alpha and beta) and this
coating leads to HV shorting problem.

Two samples were prepared and loaded into the target boat with 1 layer of heat-shied as shown in the attachment#1.
Ingredients used: np-SiC and very small about of 5% PVA to hold the powder together.

Three samples were prepared  (see my logbook#1 page 3, preparing for carbonization).
One layer of Ta foil was used to wrap around the target boat.

Target boat has a layer of niobium foil on the bottom of the boat.
A niobium foil has been made with slots to hold samples [similar to when sintering endcaps] *See

The endcaps are stacked together with a punched out disc of graphite foil placed in between each
endcap for separation so endcaps won't fuse together.

There are two types of samples being test for thermal stability:
1.  SiC-SiO2-Lys nanofiber mats
