Abstract
The practical use of boron and its compounds is extremely diverse due to its different properties. About 55 % of boron raw materials are consumed by the glass and ceramic industries for the manufacture of optical glasses, heat-insulating glass fibers, acid-resistant and refractory products, enamels, glazes, porcelain, etc. The paper considers the possibility of using colemanite to obtain enamel over steel. The optimal temperature-time regime of firing has been developed to obtain a high-quality coating and achieve the desired effect. It has been established that colemanite can partially replace cover enamel drill. On the basis of the studies carried out, it was found that the obtained experimental enamel is more refractory than the ESP-210 enamel. The optimal firing temperature for the experimental coating was established – 950 ° С, for the ESP-210 coating – 825 ° С. For uniform reflow of the experimental coating, a temperature is required that exceeds the reflow temperature of ESP-210 by 125 ° C. Colemanite-containing batch was cooked. Cooking was carried out in an electric oven at 1300 ° C for 5 hours. For further research, a slip was prepared from the experimental enamel and applied by pouring onto the plates
