fabrication of polycrystal line transparent yag ceramics by a solid State Reaction method
Journal of the American Ceramic Society, 1995Co-Authors: Akio Ikesue, Isao Furusato, Kiichiro KamataAbstract:Polycrystalline, transparent YAG (Y{sub 3}Al{sub 5}O{sub 12}) ceramics were fabricated by a solid-State Reaction method using high-purity Al{sub 2}O{sub 3} and Y{sub 2}O{sub 3} powders. The mixed powder compacts were sintered at 1,600 to 1,850 C for 5 h under vacuum. Optical transmittance in the region between the ultraviolet and infrared wavelengths for YAG ceramics (1 mm thick) sintered at 1,800 C was similar to that for a YAG single crystal.

photocurrent enhancement for ti doped fe2o3 thin film photoanodes by an in situ solid State Reaction method
ACS Applied Materials & Interfaces, 2013Co-Authors: Chunhui Miao, Tongfei ShiAbstract:In this work, a higher concentration of Ti ions are incorporated into hydrothermally grown Ti-doped (2.2% by atomic ratio) micro-nanostructured hematite films by an in situ solid-State Reaction method. The doping concentration is improved from 2.2% to 19.7% after the in situ solid-State Reaction. X-ray absorption analysis indicates the substitution of Fe ions by Ti ions, without the generation of Fe2+ defects. Photoelectrochemical impedance spectroscopy reveals the dramatic improvement of the electrical conductivity of the hematite film after the in situ solid-State Reaction. As a consequence, the photocurrent density increases 8-fold (from 0.15 mA/cm2 to 1.2 mA/cm2), and it further increases up to ∼1.5 mA/cm2 with the adsorption of Co ions. Our findings demonstrate that the in situ solid-State Reaction is an effective method to increase the doping level of Ti ions in hematite films with the retention of the micro-nanostructure of the films and enhance the photocurrent.

Comparative study of potassium hexatitanate (K2Ti6O13) whiskers prepared by sol–gel and solid State Reaction routes
Applied Surface Science, 2012Co-Authors: Mohd. Asim Siddiqui, Vishal Singh Chandel, Ameer AzamAbstract:Abstract Polycrystalline phases of the potassium hexatitanate (K 2 Ti 6 O 13 ) were synthesized by conventional solid State Reaction and sol–gel methods with a view to compare structural, electrical, optical and photocatalytic properties. Single phase K 2 Ti 6 O 13 prepared by sol–gel method (PSG) revealed higher value of dielectric constant than same obtained by the solid State Reaction method (PSS), attributed to smaller particle size in sol–gel method. Band gap (3.48 eV) of K 2 Ti 6 O 13 prepared by sol–gel method was found higher than (3.06 eV), obtained in solid State Reaction method. Additionally, K 2 Ti 6 O 13 was tested as photocatalyst on the degradation of methyl orange (MO) under UV light and found better activity for sample PSG. Morphological characteristic exhibited formation of nanorods in sol–gel route and formation of microrods in solid State Reaction method.
