PRECIPITATION OF IRON-OXIDES FROM AMMONIA-AMMONIUM SULFATE-SOLUTIONS

Das, R.P.; Anand, S. (Hydrometallurgy, 38(2), 1995: 161-173)

The precipitation studies for Fe(II) in the NH3-NH4)(2)SO-O-2 system were carried out using a factorial design of experiments. The three variables chosen were: temperature, [NH3 + NH4+] and Fe(II) concentrations. Regression ...
Fine silica powder preparation by use of a transferred arc thermal plasma reactor

Mishra, Pratima Kumari; Mohanty, B.C.; Nayak, B.B. (Materials Letters, 23(1-3), 1995: 153-156)

Highly dispersed fine silica powder has been prepared from the quartzite mineral and petroleum coke by reactive evaporation in the thermal plasma and condensation from the vapour phase. The process made use of an indigenously ...
PREPARATION AND CHARACTERIZATION OF BI2S3-PBS THIN-FILMS BY X-RAY-DIFFRACTION, SCANNING ELECTRON-MICROSCOPY AND RESISTIVITY STUDIES

Parhi, N.; Nayak, B.B.; Acharya, B.S. (Thin Solid Films, 254(1-2), 1995: 47-53)

The homogeneous coprecipitation (electroless method) technique has been utilized successfully to deposit Bi2S3-PbS alloy thin films on glass substrates. Characterization of such films have been carried out using X-ray ...
Mass-transfer conditions at a cathode support plate in an electrochemical cell

Subbaiah, T.; Venkateswarlu, P.; Das, R.P.; Raju, G.J.V.J. (Chemical Engineering And Processing, 34(6), 1995: 495-501)

The presence of turbulence promoters in an electrochemical cell increases the intensity of local turbulence which enhances the limiting current density and hence the mass-transfer coefficient at the transfer surface. The ...
HIGH-SURFACE-AREA SILICON-CARBIDE FROM RICE HUSK - A SUPPORT MATERIAL FOR CATALYSTS

Singh, S.K.; Parida, K.M.; Mohanty, B.C.; Rao, S.B. (Reaction Kinetics And Catalysis Letters, 54(1), 1995: 29-34)

Ultrafine beta-SiC with high surface area (150 m(2) g(-1)) has been synthesized by inflight processing of charred rice husk in a r.f. plasma reactor operating at atmospheric pressure. The plasma-synthesized particles were ...
SYNTHESIS, CHARACTERIZATION AND ELECTROCHEMISTRY OF A BINUCLER COPPER(II) COMPLEX OF SCHIFF-BASE DERIVED FROM 2-AMINOMETHYL-BENZIMIDAZOLE AND SALICYLALDEHYDE

Das, N.N.; Dash, A.C. (Polyhedron, 14(9), 1995: 1221-1227)

A dinuclear Cu-II compound (Cu(2)L(2)(2+)) with the phenoxide form of N-salicylidine 2-aminomethyIbenzimidazole has been synthesized and characterized on the basis of elemental analysis, UV-visible, IR and variable temperature ...
Direct flame atomic absorption spectrophotometric determination of alkalis in geochemical samples

Chattopadhyay, P. (Talanta, 42(12), 1995: 1965-1971)

Flame atomic absorption spectrometry has been used for the estimation of the alkali metal content (as Na2O and K2O) in 95 reference materials with diverse matrices (including recently introduced Polish and Chinese standard ...
ESTIMATION OF CHROMIUM IN ORES AND BENEFICIATED PRODUCTS - AN ULTRASONIC APPROACH

Patnaik, U.; Muralidhar, J. (Talanta, 42(4), 1995: 553-556)

Cr(III) slowly forms a violet complex with EDTA at pH 3.5 +/- 0.2 under normal conditions. The complex formation can be catalyzed by irradiating the reacting mixture with ultrasonic waves. Quantitative formation of the ...
CORRELATION OF NICKEL EXTRACTION WITH IRON REDUCTION IN OXIDIC NICKEL ORE BY A THERMOGRAVIMETRIC METHOD

Reddy, B.R.; Murthy, B.V.R.; Swamy, Y.V.; Ray, H.S. (Thermochimica Acta, 264, 1995: 185-192)

The reduction roasting of chromite overburden with CO/CO2/N-2 gas mixture in the temperature range 700-750 degrees C has been shown to result in the formation of metallic nickel and different lower valence states of iron, ...
THERMAL-BEHAVIOR OF SOME SALICYLATO(AMINE)COBALT(III) COMPLEXES

Das, N. (Thermochimica Acta, 257, 1995: 163-171)

The thermal dissociation of a number of salicylato(amine)cobalt(III) complexes has been studied by thermogravimetry, differential temperature analysis, UV-visible spectral analysis of intermediates and XRD of the final ...
