A glass of composition 4.8Na 2 O-25.2B 2 O 3-70SiO 2 was produced by melting silica, boric acid, and sodium carbonate mixture at about 1600 °C. Sodium borosilicate glass fiber was drawn while the glass melt was cooling to room temperature. The fiber sample was heat treated to provide spinodial decomposition and phase separation at 600 °C for 6 h. Also, a bulk glass piece was fabricated from the same chemical composition. The soluble alkali rich borate phase was removed by acid leaching process with hot dilute HCl solution. The glass produced was characterized using DTA-TG, SEM, and XRD analysis techniques. The SEM examinations revealed that nano-sized pores formed in the sample.

Preparation and microstructure of sol-gel derived silver-doped silica
Akkopru, Betul; Durucan, Caner (2007-08-01)
Silver-doped silica was prepared by hydrolysis and condensation of tetraethyl orthosilicate (TEOS, Si(OC2H5)(4)) in the presence of a silver nitrate (AgNO3) solution by two different synthesis methods. In the first synthesis route, sol-gel mixtures were prepared using an acid catalyst. In the second synthesis route, silver-doped silica gels were formed by two-step acid/base catalysis. For the same concentration of silver dopant [AgNO3]/[TEOS] = 0.015 acid-catalyzed sol-gel formed a microporous silica with a...
Synthesis of zinc borate using water soluble additives: Kinetics and product characterization
ÇAKAL, GAYE ÖZGÜR; Baltaci, Berk; Bayram, Göknur; Özkar, Saim; EROĞLU, İNCİ (Elsevier BV, 2020-03-01)
Zinc borate was synthesized from the reaction of zinc oxide and boric acid in the absence or presence of seven different water soluble additives. Additive concentration and zinc oxide particle size were varied to investigate their effect on the growth kinetics of zinc borate particles. Zinc borate particles were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and thermogravimetric analysis (TGA). Samples taken from the reaction mixture during the synthesis were analyzed for dete...
Reduction of silicon dioxide by electrochemical deoxidation
Ergül, Emre; Karakaya, İshak; Department of Metallurgical and Materials Engineering (2010)
Electrochemical reductions of porous SiO2 pellets and bulk SiO2 plate were investigated in molten CaCl2 and/or CaCl2-NaCl salt mixture. The study focused on effects of temperature, particle size of the starting material, electrolyte composition and cathode design on the reduction rate. The behavior of the cathode contacting materials was also examined. Moreover, cyclic voltammetry study was conducted to investigate the mechanism of the electrochemical reaction. Mainly, XRD analysis and SEM examinations were...
Preparation of lead zirconate titanate (Pb(Zr0.52Ti0.48)O-3) by homogeneous precipitation and calcination
Oren, EE; Tas, AC (1998-05-06)
Aqueous solutions of lead chloride (PbCl2), zirconium oxychloride (ZrOCl2.8H(2)O) and titanium tetrachloride (TiCl4), in appropriate volumetric amounts, were used as the starting materials in the synthesis of phase-pure Pb(Zr0.52Ti0.48)O-3 powders. Preparation of the phase-pure PZT powders were achieved, in the presence of urea (CH4N2O), by the chemical powder synthesis route of homogeneous precipitation.
Synthesis and characterization of conducting graft copolymers based on oligophenols
Sahmetlioglu, Ertugrul; Arikan, Ufuk; Toppare, Levent Kamil; Yuruk, Huseyin; Mart, Hasan (Informa UK Limited, 2006-10-01)
Oligo-2-aminophenol (OAF) was synthesized with oxidative polycondensation of 2-aminophenol and hydrogen peroxide in an aqueous alkaline medium at 80 degrees C. Oligo-2-aminophenol with thiophene side groups (TOAF) was obtained by the reaction of OAF and thiophene-3-acetic acid. Graft copolymers of TOAF and pyrrole were synthesized by electrochemical polymerization in p-toluene sulfonic acid (PTSA)/water medium. Characterization of the graft copolymer (TOAF-g-Py), was carried out by combination of techniques...
