The target containers end-caps were coated with TaC spray and let dry.
Each cap is wrapped with a small piece of graphite foil and inserted in the target boat. [see attached photo] |

The target container end-caps were sintered previously, but did not fully complete the sintering process [See elog entry # 119 EVAP2]
The caps are inserted in the target boat wrapped in graphite foils with 3 x Ta-heat shields. |

The purpose of this experiment is to see if the carbon mesh is suitable for coating and sintering with uranium carbide. For this test, the
mesh is coated with WC slurry (previously prepared). |

Thursday, May 29, 2014, 18:16, Cameron Hodgins, , , TARGET BOAT, In progress, Sintering several carbides on tantalum foil backing
|
Purpose: Sinter one sample of each of TiC, VC, Cr3C2, ZrC, NbC, Mo2C, TaC, and WC on 5x10 mm tantalum foil to see if the samples are usable for SEM.
Samples were prepared using a solution of PEG (2.56 g), PVB (2.45 g), paraffin oil (1.12 g), MEK (15 mL), and EtOH (23 mL). Slurries made using
0.0013 mol of each carbide with ~230 uL of the solution. Applied via paintbrush onto 5x10 mm tantalum foil. |

Auto-ramp started. Max current = 500 A, voltage = 11.05 V. Current is being increased at 2 A/min. In the first 20 minutes, the pressure went up to about
10E-6 T, but has slowly decreased since then. Everything looks ok. The system will be left until Monday morning (June 9th). |
