We have two Sievert
type instruments both of our own design. One operated manually handles
hundred miligrams. The other is currently under construction is more precise with automated control and data acquision. The latter handles sample sizes as small as few
miligrams. Both instruments allow measurements at temperatures as high as 400 oC
andd pressures up to 70 bar
Glove-box ,as in most equipment in the lab is home-made, has a capacity of slightly over 63 lt. Transfer chamber has a capacity of 0. 100 lt . The box
normally operated with positive
pressure with flow rate of argon
typically 10 ml/min,
Powder Processing Equipment .
for powder processing include ball
mill, spex mill and several attritor mills.
would handle small samples
typically 5- 10 grams
Thin Film Processing Equipment
We use thermal evaporator for thin film processing. Bell jar system
shown above enables vacuum
levels close to 10 -7
mbar. The system currently in use
employs stainlesss steel jar with
wire sealed flange allowing vacuum
levels better than 10 -8 mbar
Furnaces ( Serdar Tan,
Processing Equipment .
We have furnaces and a
swager . The latter is used quite
often in powder processing as a consolidation method. The swager has dies which would allow swaging down to 24,
19.75, 15 , 11 , 8.8 ,6.6
4.5 mm diameter .
