Determınatıon of the propertıes and productıon of borıc acıd added electro porcelaın

The need of electrical energy is raised by the development of industry and that required to transportation of energy to the more distant points. All these developments reveal the need of cheaper insulator production and the need of enhancement of insulators? technical specifications and mechanical resistance against the increasing mains voltage and external factors. In this study, by adding boric acid to electro-porcelain mass slurry, the effect on mechanical and chemical properties is assessed and whether boric acid can be used an alternative raw material source is investigated. In the study, three different prescriptions, contain % 0,1, % 0,3 and % 1 H3BO3 additive, were prepared. Then, prepared samples were shaped on vacuum presses in the laboratory. After samples were dried, they were sintered at 1255 oC degree. Particle size distribution, dry refinement, fuchsine and bending three point tests were applied to the samples. Characterizations of microstructure were done by XRD, SEM and EDS analyses. At the end of the experimental studies, it was seen that depending on additive percentage, the reduction of particle size distribution is up to % 0,3 and particle size is increasing with an increase in additive ratio. Addition of % 0,3 boric acid improved the dry resistance and ripening resistance about % 56 and % 1,6, respectively. The maximum dry reduction amount was seen on the sample that contains % 1 boric acid. In general, it was determined that the sample, which contains % 0,3 boric acid, gives closer results to operation conditions. Therefore, it was observed that the boric acid could be an alternative raw material source, if it is incorporate into electro-ceramic at a certain ratio.
