Smelting reduction studies: Scope and limitations

Jouhari, A.K.; Galgali, R.K.; Ray, H.S. (Icarism '99: Proceedings Of The International Conference On Alternative Routes Of Iron And Steelmaking, 99(3), 1999: 173-184)

It is well accepted that the blast furnace will continue as the main route for iron-making for many more years. However, its limitations have motivated researchers to look for alternative routes, particularly, those where ...
Somaclonal variation in cell suspension culture-derived regenerants of Cymbopogon martinii (Roxb.) Wats var. motia

Patniak, J.; Sahoo, S.; Debata, B.K. (Plant Breeding, 118(4), 1999: 351-354)

Plants regenerated from cell suspension cultures of palmarosa grass, Cymbopogon martinii (Roxb.) Wats, were analysed for somaclonal variation in five clonal generations. A wide range of variation in important quantitative ...
A study on the preparation of TiC reinforced cast iron composites by plasma smelting of ilmenite ore

Galgali, R.K.; Ray, H.S.; Chakrabarti, A.K. (International Journal Of Cast Metals Research, 12(1), 1999: 41-48)

TiC reinforced cast iron composites have been prepared by plasma smelting of ilmenite ore in a bed of steel scrap. The influence of magnesia and zircon coating on smelting hearth on microstructure of composites have been ...
Magnetic properties of topochemically sintered barium hexaferrite

Gumaste, J.L.; Ray, H.S.; Godkhindi, M.M.; Mukunda, P.G. (Journal Of The American Ceramic Society, 82(11), 1999: 3269-3271)

This communication describes the method of topochemical reaction sintering for the production of barium hexaferrite. Topochemical reaction sintering overcomes crucial process steps that are used in the conventional wet ...
Mass transfer conditions in an electrochemical cell in the presence of turbulence promoters

Subbaiah, T.; Venkateswarlu, P.; Das, S.C.; Das, R.P.; Raju, G.J.V.J. (Plating And Surface Finishing, 86(1), 1999: 94-98)

The presence of turbulence promoters in an electrochemical cell increases the intensity of local turbulence, which enhances the limiting current density and, consequently, mass transfer coefficients. The regularity of their ...
Microstructure-dependent coercivity in monodispersed hematite particles

Rath, C.; Sahu, K.K.; Kulkarni, S.D.; Anand, S.; Date, S.K.; Das, R.P.; Mishra, N.C. (Applied Physics Letters, 75(26), 1999: 4171-4173)

Microstructure and magnetic properties of monodispersed pseudocubic and trapezoidal particles with varying sizes prepared through the hydrothermal precipitation route are reported. The coercivity for trapezoidal particles ...
Viscosity and density of tri-n-butyl phosphate plus benzene plus toluene from 30 degrees C to 45 degrees C

Swain, N.; Panda, D.; Singh, S.K.; Chakravortty, V. (Journal Of Chemical And Engineering Data, 44(1), 1999: 32-34)

Viscosities and densities of the ternary liquid mixtures of tri-n-butyl phosphate + benzene + toluene were measured at (30, 35, 40, and 45) degrees C. The deviations in the viscosity from a mole fraction average were fitted ...
SO42-/TiO2-SiO2 mixed oxide catalyst, I: Synthesis, characterization, and acidic properties

Parida, K.M.; Samantaray, S.K.; Mishra, H.K. (Journal Of Colloid And Interface Science, 216(1), 1999: 127-133)

A series of sulfate-doped titania-silica mixed oxides have been prepared by immersing titania-silica gel in the required volume of sulfuric acid, followed by drying. The mixed oxide gel is obtained by hydrolyzing an equimolar ...
Studies on anion promoted titania. 1: Preparation, characterization, and catalytic activity toward alcohol and cumene conversion reactions of phosphated titania

Parida, K.M.; Acharya, M.; Samantaray, S.K.; Mishra, T. (Journal Of Colloid And Interface Science, 217(2), 1999: 388-394)

Phosphate impregnated titania samples with varying amount of phosphate have been prepared by solid-solid kneading as well as aqueous impregnation method. All the samples are characterized by XRD, TG-DTA, and N-2 ...
Adsorption of hexavalent chromium from aqueous solution by using activated red mud

Pradhan, J.; Das, S.N.; Thakur, R.S. (Journal Of Colloid And Interface Science, 217(1), 1999: 137-141)

Adsorption by activated red mud (ARM) is investigated as a possible alternative to the conventional methods of Cr(VI) removal from aqueous synthetic solutions and industrial effluents. Adsorption characteristics suggest ...
