John Wong | np-SiC | | TARGET BOAT | Done | Test#2: Carbonizing sol-gel TEOS + Pan nanofibers | Friday, February 26, 2016, 15:44
5 samples were prepared at UBC MTRL using Sol-gel tetraethyl orthosilicate (TEOS) coated on electrospun polyacrylonitrate (PAN).
Each sample is sandwiched in between graphite foils.
Sample labeling:
Direct, 0.2358g
Mix, 0.3486g
3X, 0.2273g
5x, 0.2079g
7x, 0.1735g
All samples are loaded in the target boat, stacking on each other. The Container is wrapped with 2X- Ta shields.
Chamber is pumping down.
Step#1 Carbonization temperature: 1600C
Saturday, February 27, 2016, 10:07
Vac at 2.5e-7 torr.
Ramping up TGHT to 300A at 1A/min. monitoring temp.
Saturday, February 27, 2016, 17:38
TGHT at 400A, temp at 1600C. Vac 1.34e-6 Torr.
Monday, February 29, 2016, 13:04
Samples have been heated at 1635C for almost 2 days.
Pressure at 2.1e-7 Torr.
Initiated cooling at 2A/min.
Thursday, March 24, 2016, 11:26
Samples were analyzed for Si using EDX. Unfortunately, no Si was found. The vapour pressure of SiO was too high for it to react with PAN to carbonize in a vacuum environment.
Will look into a different technique.

John Wong | Nb | | LP-SIS | Done | Bob/Tobi Nb samples | Thursday, February 25, 2016, 18:04 Wednesday, February 24, 2016, 17:29
Heat treatment of 2 bullet-shaped Nb samples in a LP-SIS container; it is just that we don't have a target boat.
Container is wrapped with 12" in total length. A strip of Nb foil is used as an underlayer for the samples to sit on top.
Chamber has been pumped down and current vacuum at 1e-6 Torr.
HS water check - good.
Target temperature 1400C
Ramping up to 250A; this should get to ~1300C. Will let it heat for over night and step up to 1400C tomorrow.
Wednesday, February 24, 2016, 17:59
I'm stopping the heating process because the camera is not working. I can't monitor the temperature. Tried to fit the camera; don't now why it fails to connect to the server.
Will look in to it tomorrow...
Thursday, February 25, 2016, 08:17
Initiated auto ramping TGHT at 2A/min.
Thursday, February 25, 2016, 17:33
Finally the camera is fixed.
Current temperature is at 1126C, TGHT at 250A. Will step up to reach 1400C.
Thursday, February 25, 2016, 18:04
TGHT stepped up to 335A to reach 1400C. (see attachment)
Will heat this for few hours and cool it at around 11pm tonight.
Thursday, February 25, 2016, 22:19
Samples have been heated over 4.5 hours.
Initiated cool down at 1A/min.
Friday, February 26, 2016, 15:43
done! all good.

John Wong | np-SiC | targetboat (TaC coated) | TARGET BOAT | Done | SiC Nanofiber Heat Treatment | Tuesday, January 19, 2016, 14:19
SiC nanofiber was prepared at UBC Material Engineering Sci.
4 samples are loaded in a Ta target contained (sintered with TaC coating):
Sample 1:
size: 21.70 x 21.54 mm, mass: 0.0762g, thick: 0.224mm
Sample 2:
size: 20.89mm x 23.95mm, mass: 0.0954g, thick: 0.232mm
--> Sample 1 and 2 with graphite backing foil
Sample 3:
size: 22.55 x 25.56mm, mass: 0.0082g, thick: 0.110mm
Sample 4: 16.93 x 23.82mm, mass: 0.0048g, thick: 0.086mm
--> Sample 3 and 4 with no graphite backing foil.
(see attachment)
Test#1: Heating temperature at 1600C for 24hrs.
TGHT will be adjusted accordingly. There are 2 Ta-heat shields wrapped around the container.
Chamber is currently being pumped down.
Tuesday, January 19, 2016, 16:19
Vacuum at 2.0e-6 Torr.
For 1600C, expected current is around 350A.
Stepping up TGHT gradually...
Wednesday, January 20, 2016, 14:34
TGHT was ramped up to 390A/6.63V to reach 1600C. Samples have been heated at that temp since 11pm last night.
Visual check on the fibers seem ok (see attachment).
Will continue to heat this for a total time of 24hours.
Wednesday, January 20, 2016, 22:57
Samples have been heated at 1600C for 24hours.
Initiated cooling at 1A/min.
Wednesday, January 27, 2016, 12:34
First attempt - heating 1600C. XRD result showed board "bumps" that could be SiO2? It is inconclusive.
Second attempt - re-heating the same samples, namely
Sample 1 - only the fiber
Sample 2 - with graphite backing. This sample is loaded with the fiber facing down to see how well it holds on the graphite foil. (see attachment)
TGHT will be ramped up to reach 1800C
Chamber is currently being pumped down.
Wednesday, January 27, 2016, 14:04
Water valves open; no leaks detected.
Ramping up TGHT to 400A at 2A/min
Wednesday, January 27, 2016, 18:08
TGHT is at 481A to obtain 1800C.
Visual check on Sample 2 - fiber has fallen off graphite backing foil.
Will remain heated at this temperature for over night.
Friday, February 12, 2016, 11:11
Heat treatment test#1 is complete. XRD results are inconclusive. Need to do EDX to determine Si/SiO2.

Wednesday, January 13, 2016, 10:14
Previous temperature measurement of OMEGA = 1400C is wrong due to window port being coated with SiC [see attached photos]
Will remain at TGHT = 420A for 4hrs then cool down this afternoon
Wednesday, January 13, 2016, 14:29
Remained at max setpoints for 4.5hrs.

Took out of evap2 yesterday.
Aurelia took many emissivity measurements to compare with previous data - which matched up.
The dip in emissivity before going up again around ~560A could be due to oxidation of the materials.

Tapping up manually to 2000C
Wednesday, November 25, 2015, 15:31
container was tapped up manually to 650A, slope/emissivity settings were checked.
ramped back down to 450A and tapped up manually while recording data up to 1800C [legs = 2000C]
once reached 1800C, tapped TBHT down manually to see relation of TBHT to temperature/ TGHT
remained at 1800C for ~1hr [while tapping down TBHT] before initiating auto-cool at 2.0A/min for the TGHT
see attachment for raw data.

Tapped up manually to 35A.
Vacuum stable.
IGP1 = 3.4e-7 Torr.
Initiating auto-ramp at 1.0A/min and 0.5A/min for the TGHT and TBHT respectively.
Final setpoints: 250A for the TGHT and 230A for the TBHT
Monday, November 16, 2015, 13:29
Vacuum too high.
IGP1 = 2.9e-5 Torr.
Decreasing ramping rate down to 0.5A/min and 0.2A/min for the TGHT and TBHT respectively.

Tuesday, November 17, 2015, 11:22
Tapped up manually to 1800C, realized SiC should only be tapped up to 1700C, backed off immediately down to 415A from 460A/ 1800C.
See attachment for photo of striptool/ time spent above 1700C [~20min].

Checked the temp on the inner surface (not at the spring) of the container was around 2050C at 500A.
The TaC coated spring is reading at 1900C; that's what the OMEGA is reading with the setting for 2-colors and slope at 0.98.
Lower TGHT to 450A/ 7.12V.
By comparing the data from the previous temp curve (OMEGA slope at 0.98) with no material inside the container, the voltage and current plot is aligned with the curve.
Changed OMEGA setting slope to 1.04. Current temp is reading at 1917C at 450A.
For 2-Color setting, the emissivity should be negligible. That makes me believe that different materials has different slope setting for the temp reading.
One thing to note is that, the sintering temp of TaC is around 1900-2000C. It was clear that the container was fully sintered with TGHT at 450A.
Will need to gather more data with different material to understand the slope setting better.
Try:
SiC at 1700C, slope at 1.04
ZrC at 1900C, slope at 104
Ta at 1900C, slope at 0.98.
Compare the data...
