The coated container was wrapped in 4 Ta foil heatshields.

Target temperature on OMEGA= 1850-1900 C

OMEGA slope:= 0.990

Target time at max temperature = 2 hours

Final Current TBHT= N/A

Final TGHT current= ~400A (adjustable)

Heating autoramp starged at 2A/min(1A/30s) on  TGHT  100A

Then at 4A/min  to =400 A.

Good vacuum = 5.0 e-04 Torr

Bad vacuum = 5.0E-02 Torr

 IGP1 initial =2.2e-06 Torr

IGP1= 2.31e-06 Torr

TGHT 98.0 A (RD), 1.35 V

Start ramping at 2A/min to 400A

Note: the coating looks really good .  The second sintering on the second coating was 2 hours.  Will test the coating during graphite material conditioning.
