Development Technology of Electrical Conductance Ceramics
Year: 2020
Type: article
Abstract: The article considers the influence of the technological parameters of the composite ceramics production on the specific volume resistivity of the composition and, consequently, on the protective properties against the effects of electromagnetic radiation. The technological parameters included the preparation method, the averaging time of the raw materials, both the pressing and second calcination pressure. Based on the complex of studies carried out, the following technological parameters of production were established: duration of grinding – 60 minutes; the moisture content of the press powder is 6.2%; pressing pressure – 25 MPa; first calcination temperature – 1060 °С; temperature of the second calcination –1060 °C. The developed technology can be applicated at enterprises that produce ceramic tiles according to high-speed calcination. The resulting material can to protect biological and technical objects from the action of electromagnetic radiation. Further research at selecting a glaze coating for the developed ceramics is aimed.
