Abstract:
In this study, production of porcelain for the ceramic dielectric applications by using inexpensive natural raw materials or waste materials was undertaken. The principal raw materials of porcelain, such as kaolin, feldspar and quartz are relatively inexpensive and readily available. The basic electro-porcelain composition was selected consisting of 20% clay, 30% kaolin, 30% potash-feldspar and 20% quartz. The samples synthesized were characterized by X-ray diffraction (XRD) technique. The dielectric properties of porcelain bodies prepared, e.g. dielectric constant, dielectric loss tangent (tan δ) and loss factor, were investigated. Dielectric measurements have been carried out at 1 KHz in the ambient temperature. The dielectric constant ε' of standard porcelain and porcelain with boric acid samples sintered at the most proper sintering temperature 1310°C were about 8 and 16 respectively. The value of dielectric constant of porcelain with boric acid is higher as compared to standard porcelain.
