when cleaning mortars with Kings water (HCl + HNO3)
Keep powders in closed jars during transport and storage
Facial shield when taking powders from furnace and using
the hydraulic press
: Dispose all disposables and weighing dishes contaminated
with powders (nanoparticles) in the black waste bin
Clean the mortar with Vim and dispose the waste into waste
bin V (heavy metals)
Clean the mortar with Kings water and dispose into waste
bin V (heavy metals)
Dispose crucibles when contaminated in the black waste bin
Clean powder spills from the base of the furnace
Clean oil spills from the hydraulic press
: Planet mill Fritsch P6
Alumina Crucible
Loomis platen press
Nabertherm 1300 degree furnace for boiling off carbonic acid
Entech 1500 degree furnace for sintering pellets
D8 powder diffractometer
: Monday 12th september
Tuesday 20th september
: 1st day calculation the amount of powders and checking
disposables and make sure everything is abundant available
2nd day weigh powders use of planet mill and boiling off
carbonic acid in Nabertherm furnace
3th day checking powder with D8 and press pellets when the
carbonic acid is boiled off and place pellet in Entech else
continue boiling off carbonic acid in Nabertherm furnace
4th day check pellet with D8 when phase pure pellet ready
else powder sample and make new pellet and place in
Entech furnace
5th day check with D8 when phase pure pellet ready else
continue with homogenizing sample and repeat step
8th and/ or 9th day check with D8
: No need all lab work is done within 09:00 and 16:00
