Description
Summary:TF124.5; The characterization of feldspar for electric porcelain and the behaviour of these materials after heating at 1230℃ were studied.X-ray diffraction (XRD) and scanning electronic microscopy (SEM) were used to identify the present phases and the densification level.Feldspar sand was treated by flotation. The floated feldspar is constituted by microcline, quartz, and minor amounts of albite. The microstructure of sintered feldspar at 1230℃ is essentially vitreous with open microporosities. The dielectrical properties of composites were characterized by using the induced courant method (ICM), which indicates that the charge trapping capacity depends on the mineralogical and chemical composition of feldspar.
