Matter

Name: Water ice particles 67±31μm containing 0.22wt% NH4-nontronite in intra-mixture

Family: solid
Comments: Inside the particles, the minerals are probably concentrated between the water crystals (as seen in Poch et al., 2016b).

Processing steps

Step	Date	Type	Process	Changes
#1	2019-04-23	mixing	Mixing of 0.22 wt.% NH4-nontronite powder in liquid ultrapure water. By magnetic stirring for about 1 hour.	When dispersed in liquid water, the nontronite grains are exfoliated into individual mineral layers, called platelets.
#2	2019-04-23	mechanical	The liquid suspension is injected into a sonotrode and spread out as a thin film on the conical shaped nozzle surface at the output of the sonotrode. Ultrasonic vibrations delivered to the sonotrode nozzle disintegrate the liquid into micro-droplets.	Spherical droplets are formed.
#3	2019-04-23	thermal	The droplets of NH4-nontronite and water, initially liquid, undergo solidification as they contact the liquid nitrogen	Spherical icy particles of NH4-nontronite and water are formed.
