Nov 15, 2019· perlite and vermiculite are both mined and then heated, so it's sustainability is suspect. perlite industry says they offset carbon processing, which means they're not green. they also say there is plenty and we will have it for generations to come, but that means it's finite and if you're looking into regenerative ...
The ultrasound treatment of low-charge vermiculite from Ojén is a new method for obtaining 18 Å Al-pillared vermiculites. The ultrasound treatment using H 2 O 2 in the medium produces a significant delamination and a decrease of the particle size and the layer charge leading to the Al–polymer intercalation.
