Effects of hydrothermal post-treatment on microstructures and morphology of titanate nanoribbons
Abstract
Titanate nanoribbons were prepared via a hydrothermal treatment of rutile-type TiO{sub 2} powders in a 10 M NaOH solution at 200 deg. C for 48 h. The as-prepared titanate nanoribbons were then hydrothermally post-treated at 150 deg. C for 12-36 h. The titanate nanoribbons before and after hydrothermal post-treatment were characterized with FESEM, XRD, TEM, UV-VIS and nitrogen adsorption-desorption isotherms. The results showed that the hydrothermal post-treatment not only promoted the phase transformation from titanate to anatase TiO{sub 2}, but also was beneficial to the removal of Na{sup +} ions remained in the titanate nanoribbons. After hydrothermal post-treatment, the TiO{sub 2} samples retained the one-dimensional structure feature of the titanate nanoribbons and showed an obvious increase in the specific surface area and the pore volume.

Single-crystalline TiO{sub 2} nanomaterials were synthesized by hydrothermally treating suspensions of H-titanate nanotubes and characterized by XRD, TEM, and HRTEM. The effects of the pH values of the suspensions and the hydrothermal temperatures on the phase composition and morphology of the obtained TiO{sub 2} nanomaterials were systematically investigated. The H-titanate nanotubes were predominately transformed into anatase nanoparticle with rhombic shape when the pH value was greater than or equal to 1.0, whereas primarily turned into rutile nanorod with two pyramidal ends at the pH value less than or equal to 0.5. We propose a possible mechanism for hydrothermal transformation ofmore »

Calcium titanate (CaTiO{sub 3}) dielectrics prepared by plasma spray and post-deposition thermal treatment
Highlights: • Calcium titanate was sprayed by two different plasma spray systems. • Significant improvement of dielectric properties after annealing was observed. • Calcium titanate self-supporting parts can be fabricated by plasma spraying. - Abstract: This paper studies calcium titanate (CaTiO{sub 3}) dielectrics prepared by plasma spray technology. A water stabilized plasma gun (WSP) as well as a widely used gas stabilized plasma gun (GSP) were employed in this study to deposit three sample sets at different spray conditions. Prepared specimens were annealed in air at atmospheric pressure for 2 h at various temperatures from 530 to 1170 °C. X-raymore » -
Fatigue crack propagation in dual-phase steels: effects of ferritic-martensitic microstructures on crack path morphology
Characteristics of fatigue crack propagation in dual-phase steels have been investigated in a high purity Fe-2Si-0.1C steel with the objective of developing ferritic-martensitic microstructures with maximum resistance to fatigue crack extension while maintaining high strength levels. A range of crack growth rates has been examined from 10/sup -8/ to 10/sup -3/ mm per cycle in duplex microstructures where intercritical heat treatments were used to vary the proportion, morphology, and distribution of the ferrite and martensite phases. Microstructures containing fine globular or coarse martensite in a coarse-grained ferritic matrix yielded the highest ambient temperature fatigue threshold stress intensity range ..delta..K/sub 0/more » -
Direct synthesis of Al-SBA-15 containing aluminosilicate species plugs in an acid-free medium and structural adjustment by hydrothermal post-treatment
A series of Al-SBA-15 with controllable aluminosilicate plug structures inside straight mesopores has been hydrothermally synthesized in a one-step synthesis in an environmentally friendly acid-free medium, using triblock copolymer Pluronic P123 as a structure-directing agent, water as solvent, tetraethyl orthosilicate (TEOS) and aluminum nitrate (Al(NO){sub 3}·9H{sub 2}O) as silica and aluminum sources, respectively. The effects of the P123/Si molar ratio in the initial solution and aging temperature on the structural properties of the resulting materials were investigated by powder X-ray diffraction (XRD), nitrogen adsorption–desorption at 77 K, transmission electron microscopy (TEM), scanning electron microscopy (SEM), thermogravimetric (TG), FT-IR spectra andmore » -
Effects of composition and heat treatment on the microstructures of mica vitrocrystalline materials
During the last decade a new mica glass-ceramic based on fluorphlogopite has been made, which is readily worked, mechanically strong, and chemically stable. (Items of this material are readily worked with steel tools on ordinary metal-working machines, and they have high mechanical strength and good shock and thermal resistance as well as elevated values for the electrical parameters.) This paper considers the microstructures of mica vitrocrystalline materials in relation to the heat-treatment conditions for glasses of various compositions. It is concluded that it is desirable to use two-stage crystallization to produce glass-ceramics based on fluorphlogopite with a given structure; andmore »
