Titanium powder from titanium dioxide by molten salt electrolysis - Preparation and characterization study

Mishra, Pratima Kumari; Mohanty, J.; Rath, P.C.; Nayak, B.B.; Paramguru, R.K. (Transactions Of The Indian Institute Of Metals, 59(4), 2006: 463-468)

Studies on preparation of titanium by electrodeoxidation of sintered titanium dioxide pellets in molten calcium chloride bath is reported. X-ray diffraction, scanning electron microscopic and electron probe microanalysis ...
Titanium production technology scenario - An overview

Mohanty, J.; Rath, P.C.; Paramguru, R.K.; Misra, V.N. (Transactions Of The Indian Institute Of Metals, 59(1), 2006: 1-15)

Titanium, in spite of its abundance and numerous favourable properties, is not in use to the extent it deserves. This is due to its prohibitive cost compared to other structural metals such as steel or aluminum. This article ...
In-flight thermal plasma processing of pre-reduced ilmenite

Mukherjee, P.S.; Samal, S.; Mukherjee, T.K. (Transactions Of The Indian Institute Of Metals, 59(3), 2006: 353-358)

An inflight thermal plasma processing route for processing metallized ilmenite has been demonstrated for the production of TiO2 rich slag & iron metal. The thermal plasma reactor uses a suitably designed powder feeder for ...
Catalyst assisted graphitisation of calcined petroleum coke (CPC) in an extended argon arc plasma reactor (EAAPR)

Gumaste, J.L.; Singh, S.K.; Galgali, R.K.; Mukherjee, P.S. (Transactions Of The Indian Institute Of Metals, 59(4), 2006: 497-502)

In the present investigations the effect of addition of boron to the calcined petroleum coke (cpc) charge on its high temperature graphitisation behaviour is studied. An extended argon arc plasma reactor (EAAPR) of 35 kW ...
Using phosphorus doping of MoO3/ZSM-5 to modify performance in methane dehydroaromatisation

Burns, S.; Hargreaves, J.S.J.; Pal, P.; Parida, K.M.; Parija, S. (Journal Of Molecular Catalysis A-Chemical, 245(1-2), 2006: 141-146)

The performance of methane dehydroaromatisation catalysts prepared by the impregnation of H-ZSM-5 with ammonium heptamolybdate and phosphomolybdic acid precursors has been found to be different. Particular attention has ...
Effect of dissolved organic matter on the adsorption and stability of As(V) on manganese wad

Mohapatra, D.; Mishra, D.; Chaudhury, G.R.; Das, R.P. (Separation And Purification Technology, 49(3), 2006: 223-229)

The efficiency of manganese wad to adsorb As(V) was tested as a function of pH, contact time, adsorbent dosage, and initial As(V) concentration. The effect of dissolved organic matter (DOM) on the adsorption properties of ...
Preparation, characterisation of molybdophosphoric and tungstophosphoric acid intercalated zinc aluminium hydrotalcite-like compounds and their catalytic evaluation towards the oxidative bromination of phenol

Parida, K.M.; Parija, S.; Das, J.; Mukherjee, P.S. (Catalysis Communications, 7(11), 2006: 913-919)

Oxybromination of phenol was carried out using an efficient and highly regioselective catalyst that is molybdophosphoric acid (MPA) and tungstophosphoric acid (TPA) intercalated zinc aluminium hydrotalcite-like-compounds ...
Distribution of trace elements in coal - Lithotypes from Talcher coalfield, Orissa

Mohanty, J.K.; Misra, S.K.; Mohapatra, B.K. (Journal Of The Geological Society Of India, 68(4), 2006: 675-684)

Trace element distribution in bulk coal and lithotypes viz. durain, fusain, clarain and vitrain in two coal seams of two geological formations of Karharbari and Barakar from Talcher coalfield, Orissa is reported and compared ...
Liquid phase bromination of phenol over titania pillared zirconium phosphate and titanium phosphate

Das, D.P.; Parida, K. (Catalysis Communications, 7(2), 2006: 68-72)

The liquid phase bromination of phenol was carried out using titania pillared zirconium phosphate (ZrP) and titanium phosphate (TiP) as catalysts, KBr as brominating agent and hydrogen peroxide as an oxidant by varying ...
Thermal dehydration characteristics of hydrated salts: A critical review

Kanungo, S.B.; Mishra, S.K. (Journal Of The Indian Chemical Society, 83(10), 2006: 1006-1017)

Thermal dehydration characteristics of hydrated salts have been critically reviewed. Structural characteristics of salts, especially the nature of bonding of water molecules wit h the metal ion, occurrence of melting, ...
