Abstract
The physio-chemical method to break down raw materials utilizes a pressure- and temperature-controlled vessel to hold the raw materials in an expansive solidifier solution. The pressure and temperature are cycled to create large solution volume increases, to create high supersaturation ratios with reset to the hydrated phases of the salt or other chemicals, to produce rapid precipitation of the hydrated form of the salt or other chemicals from a supersaturated solution, and to produce rapid volume increases in the solution system. The rapid volume increases in the system create undrained crystallization pressures within the raw materials that break down the raw materials in to smaller pieces with higher surface area.
