Microwave synthesis of nano-sized barium titanate

Mechanical properties of La₂O₃ and Nb₂O₅ doped Al₂O₃ ceramics prepared by microwave sintering

“…The coupling efficiency of microwaves directly to the material is the primary advantage of microwave sintering as compared to conventional sintering. 19), 20) The volumetric heating ability of microwave allows for more rapid and uniform heating, resulting in decreased sintering temperature and time. Figure 3 presents the surface SEM images of the thermally etched 5Nb 2 O 5 /xLa 2 O 3 (95x)Al 2 O 3 composite ceramics.…”

High-Frequency Dielectric Properties of Nanocomposite and Ceramic Titanates

“…Nanoscale barium titanate powders were synthesized by microwave assisted mechano-chemical route [8], [9]. Microwave heated powders showed extra high dielectric constant value and low dielectric loss.…”

Microwave-assisted synthesis of SrFe12O19 hexaferrites

“…The sol-gel auto-combustion method, which has been applied in synthesis of inorganic materials widely [4,5], is considered as the candidate method to synthesize single domain SrFe 12 O 19 ferrites [6]. In this method, the calcination condition to form single-phase strontium hexaferrite is about 900 1C for 4 h. In recent studies, it has been shown that nano-sized inorganic powders [7], barium titanate [8] and SiO 2 [9] can be prepared by the microwave synthesis process. Microwave heating is an in situ mode of energy conversion and the microwave heating process is fundamentally different from conventional heating process.…”
