Effects of Fe₂O₃ on the Properties of Iron-Red Fancy Glaze with Low Thermal Expansion (II)

Abstract:

In this paper, the fancy red brown glaze with suitable red spots was prepared. Effects of Fe₂O₃ contents on the glaze were studied. Glaze surface quality was investigated. X-ray diffraction (XRD) were analyzed the phase. The results showed that with the increase of Fe₂O₃ contents, the obtained sample changed from black as the base color with little red spots, to the red brown as the base color with uniform red spots, and then to the red brown as the base color with crowded red spots. It indicated that the suitable Fe₂O₃ content is important for good glaze surface quality with red spots. When Fe₂O₃ content is 10%, the iron-red fancy glaze with low expansion coefficient could be well matched with the body. It is due to the presence of petalite phase, corderite phase and a - Fe₂O₃ crystals.
