“…BaCO 3 + H 3 BO 3 and BaB 2 O 4 can significantly lower the sintering energy of BaTiO 3 . The relative density for the sample (CM) is the highest (≈94.0%) [21]. To help understand this behavior DTA was performed: BaTiO 3 + 10mol%BaCO 3 + H 3 BO 3 .…”

Microwave sintering is a process in which target materials absorb microwaves and heat themselves from the inside. When microwave energy is effectively absorbed by the material, energy consumption for the sintering can be reduced. Our study is focused on the microwave sintering of BaTiO3 to more rapidly obtain dense ceramics with specific characteristics. For BaTiO3-based electronic components, the sintering temperature is too high for manufacture, so various additives are used to decrease the sintering temperature without undue worsening of the electrical characteristics. In this work, during microwave sintering, BaCO3, H3BO3, BaB2O4 and LiF were added to form a liquid. The effects of the amount of liquid phase on density and dielectric properties were investigated. BaTiO3 sintered with BaCO3 and H3BO3 showed dielectric properties, whereas BaTiO3 sintered with BaB2O4 had semiconducting properties with PTCR characteristics. Also, LiF-added BaTiO3 indicated a dielectric constant in which the peak shifts to lower temperatures with higher LiF concentrations.

The drying and sintering processes require large quantities of energy. If this energy could be used more efficiently, less would be consumed. In this research, the effect of the microwave on the manufacturing process of ceramics where heat was needed was examined. We obtained the following results when oxide ceramics were dried and sintered by microwave technique: In drying process, slip cast bodies were dried rapidly by microwave drying and compared with those dried by conventional drying techniques. In sintering process, power consumption and efficiency were lower with the time-control method than with the power-control method. The power-control method gave more precise temperature control under our experimental conditions.

A comparative analysis of the structural characteristics of LiZnTi ferrites sintered at the temperature of 1280 and 1360 K was performed. The qualitative and quantitative X-ray diffraction (XRD) analysis of the samples, main phase structural analysis, and unit cell parameters were carried out using the non-standard method (Rietveld method). Diffraction patterns were recorded on an ARL X'TRA diffractometer in the CuKα1+α2 and CuKβ scanning modes.
