Processing steps
Step Chronology Date Type Process Changes
#1 before layer formation 2019-06-01 mechanical grinding bulk meteorite reduced to grains with size lower than 10 microns
#2 before layer formation 2019-06-01 thermal 500 mg of commercial ultrapure KBr powder was heated under ambient air to 80°C overnight (~10h) removal of adsorbed/hydration water in KBr powder
#3 before layer formation 2019-06-01 mixing homogeneous mixing 1.0 mg of grinded meteorite was weighed and mixed with 500 mg of dried commercial ultrapure KBr powder
#4 during layer formation 2019-06-01 pressure pressure formation of a pellet of 13mm diameter and 0.8 mm thick under 400 bars of pressure
