Humidity sensitivity characteristics of BaTiO3 ceramics with PMMA additive at various working temperatures
Özet
Barium titanate samples were prepared by a traditional powder metallurgy method. High-purity powders were mixed by ball-milling in order to produce powder mixtures. The resultant mixtures were dried, sieved and were uniaxially pressed into green samples. Green samples were then sintered at 1200-1500 degrees C for 6 h in air to form a barium titanate phase. The average grain size and microstructural features were determined for each composition. The effects of porosity and working temperatures on the barium titanate ceramics were investigated by microstructural analysis and electrical conductivity measurements and the results were evaluated in terms of porosity.
