MOLD FOR MANUFACTURING A BODY MADE OF A POROUS MATERIAL
A mold for manufacturing a body made of a porous material derived from precursors of the porous material in a sol-gel process carried out within the mold can have a lower part defining an interior volume for receiving the precursors of the porous material, wherein the interior volume defines the shape of the body to be manufactured, and at least a first opening through which the body is removable from the lower part. Surfaces of the lower part facing the interior volume are at least partially provided with a coating made of a material that is electrically dissipative and non-sticky to a gel formed from the precursors of the porous material and/or the body.
