Influence of Iron Oxides on the Properties of Unfluoridated Enamel Frit Glass and Coatings
The influence of iron oxides on the properties of unfluoridated enamel glass frit and coatings in the system of Na2O – B2O3– SiO2 has been studied. It has been determined that the introduction of Fe2O3 additive in the amount of 0.4 mol % instead of SiO2 into an unfluoridated glass enamels improves the optical-color characteristics of the coatings, pigmented with selenium cadmium red.
