Development of a sol-gel technique for obtaining sintering activators for engobe coatings

Abstract: Розроблено технологію виготовлення склозв'язок-активаторів для інтенсифікації спікання керамічних матеріалів, зокремаангобних покриттів. Проведено порівняльний аналіз склозв'язок, отриманих за допомогою традиційної варки скла та шляхом золь-гель синтезу. Встановлено значну ефективність останнього, оскільки зменшуються енерговитрати на термообробку композиції (замість варки скла при 1300-1400 о С потрібна термообробка гелю до 600 о С) та підвищується однорідність склозв'язки (хімічний склад композиції усереднює… Show more

“…The dominant mass transfer mechanisms are grains regrouping, dissolving-deposition and the reaction on the grains' boundaries. The problem of harmonization of the shrinkage processes in the ceramic base and the coating is raised and partially solved in research [12]. It was determined that the introduction to the engobe composition of the vitreous activator, received by the sol-gel method, allows the intensification of sintering of the engobe layer and improvement of its interac-tion with the ceramic base during annealing.…”
