Enamel is widely used in various industrial fields because it has excellent properties such as beautiful color, gloss, excellent corrosion resistance, wear resistance and fire resistance, high temperature stability, etc. Enamel is a composite material consisting of glass coating that is melted and chemically bonded on a metal or its alloy. The physicochemical and mechanical properties of enamel coatings including corrosion resistance and wear resistance are mostly determined by enamel material called frit. The most widely used enamel frit is a glass material composed of inorganic materials that are added to the borosilicate-based glass material to provide physical properties such as acid resistance, alkali resistance, heat resistance and wear resistance.
The final physicochemical and mechanical properties of material are controlled by the crystallization process occurring during the calcination process. Therefore, it is important to know crystallization kinetics well in order to optimize the parameters affecting the properties.
The crystallization kinetics of different silicate-based glasses has been studied much in several methods. However, few investigations have been done on the crystallization kinetics of sodium borosilicate-based glass.
Kim Kwang Myong, a researcher at the Institute of Nano Science and Technology, investigated the non-isothermal crystallization behavior of sodium borosilicate-based glass materials used as a bottom material of low carbon steel enamel by DSC method.
In order to study the crystallization process of Na2O-B2O3-SiO2 based materials, he prepared sodium borosilicate-based glass materials used as ground coating material of steel enamel by melting and quenching.
He analyzed the experimental data by the methods proposed by preceding researchers to provide theoretical support for the preparation of good-quality sodium borosilicate-based glasses and to design a practical procedure.
