SYNTHESIS OF ULTRAFINE SIC FROM RICE HULLS (HUSKS) - A PLASMA PROCESS

Stachowicz, L.; Singh, S.K.; Pfender, E.; Girshick, S.L. (Plasma Chemistry And Plasma Processing, 13(3), 1993: 447-461)

Heat-treated rice hulls have been used as precursor material for synthesis of ultrafine SiC in a RF plasma reactor. Rice hulls containing finely distributed silica and active carbon act as a source for SiC formation. The ...
BIOPRECIPITATION OF COPPER FROM AQUEOUS-SOLUTION USING DESULFOVIBRIO SP

Panchanadikar, V.V.; Kar, R.N. (Biohydrometallurgical Technologies, Vol 1: Bioleaching Processes, 1993: 595-603)
RECOVERY OF IRON-ORE SUPER FINES AND WATER FROM SLIMES OF BOLANI IRON-ORE WASHING PLANT

Rao, G.V.; Ansari, M.I. (Transactions Of The Indian Institute Of Metals, 46(2), 1993: 51-55)

In India around 7 million tonnes of iron slimes resulting from mechanised iron ore washing plants were being rejected annually. Since the slims contain 53 to 63% Fe, retrieving such valuable fines is the immediate need ...
STUDIES ON LARGE-SCALE SINTERING OF CHROMITE FINES

Dasgupta, R.; Banerjee, G.N.; Ray, S.C.; Jouhari, A.K. (Transactions Of The Indian Institute Of Metals, 46(1), 1993: 41-44)
BONDING EFFECTS AND ELECTRONICS STATES IN BA1-XSRXTIO3 SYSTEM

Acharya, B.S.; Rajeev; Pradhan, L. (Japanese Journal Of Applied Physics Part 1-Regular Papers Short Notes & Review Papers, 32(1A), 1993: 195-197)

X-ray emission spectra in stoichiometrically highpurity Ba1-xSrxTiO3 (X = 0 to 1) powder have been investigated because of the poor understanding of the physics of electronic structure in such systems. The Sr Kbeta emission ...
CYCLOSIZER IN THE CHARACTERIZATION OF ORES

Das, B.; Reddy, P.S.R.; Narasimhan, K.S. (Transactions Of The Indian Institute Of Metals, 46(2), 1993: 89-91)
QUICK ESTIMATING FOR THERMAL-CONDUCTIVITY

Sastri, S.R.S.; Rao, K.K. (Chemical Engineering, 100(8), 1993: 106-107)
REDUCTION OF IRON-ORE FINES BY COAL FINES IN A PACKED-BED AND FLUIDIZED-BED APPARATUS - A COMPARATIVE-STUDY

Haque, R.; Ray, H.S.; Mukherjee, A. (Metallurgical Transactions B-Process Metallurgy, 24(3), 1993: 511-520)

Reduction of iron ore fines by coal fines in packed and fluidized beds has been studied. The investigation includes study of the kinetic aspects of reduction, carbon and sulfur content of the direct reduced iron (DRI) ...
A RAPID TITRIMETRIC DETERMINATION OF D2EHPA AND M2EHPA

Rao, Y.R.; Acharya, S. (Hydrometallurgy, 32(1), 1993: 129-135)

The use of impure D2EHPA in solvent extraction of metal ions leads to many process problems. Analysis of the quality of D2EHPA before use is warranted. The titrimetric estimation of D2EHPA containing M2EHPA of various ...
MASS-TRANSFER RATES IN AN ELECTROCHEMICAL-CELL

Subbaiah, T.; Das, S.C.; Das, R.P. (Hydrometallurgy, 33(1-2), 1993: 153-163)

Local mass transfer conditions in an electrochemical cell were obtained at various spatial locations with turbulence created by electrolyte circulation, or by an impeller, or by employing both simultaneously. For the cell ...
