“…The addition of 20 and 30 ppm silica showed a homogeneous surface, and almost no corrosion products were visible on the steel surface (Figures 7(c) -7(d)). Increasing the sodium silicate concentration causes the formation of a thicker film, this explains the better corrosion properties of the prepared sodium silicate-coated mild steel [38]. However, at a sodium silicate concentration of 30 ppm, the coating resistance was lower than 20 ppm.…”

Study of sodium silicate from rice husks as coating material is reported. The extraction was conducted via precipitation method with sodium hydroxide, nitric acid and ethanol at pH 8. The resulting silica was tested as hydrophobic coating by coating it on a glass surface. Based on the value of the contact angle, silica has good hydrophobic properties. The highest hydrophobic properties were obtained from sample, which labeled as Si10A:Si5B with an average contact angle of 105.3 °. Investigation of the potential application of sodium silicate as an inhibitor of corrosion has been conducted by coating it on steel surfaces. The effect of the concentration of sodium silicate was conducted at 0, 10, 20 and 30 ppm and found that the morphology of steel coated with 20 ppm has the lowest corrosion rate with 81 % inhibition efficiency. HIGHLIGHTS The amorphous silica was successfully synthesized from rice husk using the precipitation method The silica from rice husk shows hydrophobic properties with a contact angle of 105.3 ° Sodium silicate from rice husk has the ability as a corrosion inhibitor and has an inhibition efficiency of 81 % for 20 ppm GRAPHICAL ABSTRACT

“…Instead of synthesizing glass with SCBA, there are other products with diverse applications, such as sodium silicate, which can be used as a binder in concrete, in the synthesis of aerogels for water remediation, as a raw material in cosmetic and paper industries, in the synthesis of high-performance magnets, and in the synthesis of anticorrosive coatings for metals and hydrophobic coatings for ceramics [ 6 , 7 , 8 , 9 , 10 ]. SCBA has the drawback of having a diverse and complex composition; the amount of SiO 2 is not always the same, and its other components can interfere with the synthesis of glass and glass–ceramics.…”

“…The use of a carbonate instead of an oxide has some implications, such as stoichiometric calculations, an increase in reaction time because the carbonate must be decomposed prior to the reaction, and the subsequent release of CO 2 to the atmosphere because of decomposition (Equation (1)). Since the applications of sodium silicate are focused on the solution [ 9 , 10 , 16 ], the increase in porosity and the mechanical properties of the material obtained are not relevant; thus, in this case, the disadvantages presented of using SCBA have no relevant impact on the result. Since the composition of the ash varies according to geographical location, a characterization is necessary before its use.…”

To reduce the environmental impacts from sodium silicate synthesis, a ceramic method was suggested, with sugarcane bagasse ash (SCBA) as the source of silicon dioxide and sodium carbonate. Although the production of sodium silicate is carried out on a large scale, it should be noted that its process requires temperatures above 1000 °C; it also requires the use of highly corrosive agents such as sodium hydroxide and chlorine gas to neutralize the remaining sodium hydroxide. In the present study, the synthesis temperatures were reduced to 800 °C with a reaction time of 3 h by pressing equimolar mixtures of previously purified SCBA and sodium carbonate; then, heat treatment was carried out under the indicated conditions. The resulting materials were analyzed with Fourier transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD). Among the crystalline phases, calcium disodium silicate was identified, in addition to sodium silicate; thus, it was inferred that the other components of the ash can interfere with the synthesis of silicate. Therefore, in order to obtain the highest composition of sodium silicate, a leaching treatment of the SCBA is required.
