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.
