Alkaline earth metal silicates as well as many polyvalent metals silicates can be obtained through aqueous solutions reaction between an alkali silicate solution and solution of metal salts. The vitrification of the oxide compositions, established by the necessary molar ratios for the projected glass is realised by calculating the the concentration of chemical precursors, through their reaction directly on the substrate. The sodium silicate viscosity in aqueous solution and the viscosity of nitrogenated compounds or oxalate necessary in the silicates synthesis is compatible with the necessary viscosity of for ink-jet cartridges. The necessary silicates forming reactions were studied directly on the deposition support, so that the functional characteristics of the multicompartment ink-jet cartridges were used.
