Mechanical properties of electroporcelain as a function of temperature and compacting pressure
Popis výsledku v původním jazyce
High voltage insulators are an integral part of the electrical infrastructure worldwide and are prepared by compacting. For this reason, it is essential to optimize the production process, especially from the economical and environmental points of view. This study aims to find the influence of the compaction pressure and firing temperature on the microstructure, mechanical properties, and matrix density of electroporcelain samples. The C-130 type electroporcelain was prepared with compaction pressures ranging from 70 MPa to 110 MPa and subsequently fired at 1100 degrees C, 1200 degrees C, 1300 degrees C, and 1400 degrees C. The results show that the higher compression pressure does not lead to a significant improvement in the studied mechanical properties (flexural strength, Young's modulus, and Vickers hardness). On the other hand, the firing temperature positively affects the me-chanical properties of the samples. Also, with an increase in the firing temperature the matrix density is decreasing due to the formation of closed porosity above 1200 degrees C. The mechanical properties reached their maximum values after firing at 1300 degrees C.
