Abstract
This study presents the development of a microcontrolled system for the manufacture of ceramic materials with a defined pore structure. This technique, known as freeze casting, allows for the control of pore formation in different materials through the sublimation of solvent crystals solidified under cryogenic conditions. The proposed equipment uses a PID type control to maintain the temperature with a maximum variation of ±1 ºC, in the range of -196 ºC to -130 ºC. The effectiveness of the equipment was validated through the production of graphene oxide and chitosan monoliths. Characterization was done using Scanning Electron Microscopy. In which it can be verified the variation in the pore structure using different freezing temperatures
