Abstract: A process for the addition, incorporation, distribution and/or fixation of a portion of sulphuric acid to/in a “material of interest” which is intended to include or be provided with the improved properties, any starting materials, phases, layers, internal regions or surface thereof, in the natural state, before, during or after formation/production thereof (where applicable) or when already there (new, used or existing), preferably using a carrier, preferably water. Material resistance is achieved for matter, objects, fluids, products, substances and materials, and controlled synthesis of structures, incarbonization, heat impressions (following exposure to temperature and pressure variations, a situation that results in an increase in material hardness with carbon retention and heat impression in the area affected by heat) are enabled, resulting in products and use thereof.
