Processing steps
Step Chronology Date Type Process Changes
#1 before layer formation 2012-04-06 mechanical grinding bulk meteorite reduced to grains with size lower than 10 microns
#2 before layer formation 2012-04-06 thermal 300 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 2012-04-06 mixing homogeneous mixing 1.0 mg of grinded meteorite was weighed and mixed with 300 mg of dried commercial ultrapure KBr powder
#4 before layer formation 2012-04-06 pressure pressure formation of a pellet of 13mm diameter and 0.8 mm thick under 400 bar of pressure
