Study on the various factors affecting the quality of precipitated non-metallurgical alumina trihydrate particles

Pradhan, J.K.; Gochhayat, P.K.; Bhattacharya, I.N.; Das, S.C. (Hydrometallurgy, 60(2), 2001: 143-153)

Processes for production of superfine white alumina trihydroxide (ATH) powders from actual plant Bayer liquor have been developed for use in non-metallurgical applications. The specialty grade hydroxides suitable for ...
Thermal decomposition of precipitated low bulk density basic aluminium sulfate

Bhattacharya, I.N.; Gochhayat, P.K.; Mukherjee, P.S.; Paul, S.; Mitra, P.K. (Materials Chemistry And Physics, 88(1), 2004: 32-40)

Hydrated basic aluminium sulfates (BAS) are of great importance as precursor material for the preparation of activated and high pure calcined aluminas. Low bulk density category BAS powders have superior quality over higher ...
Wet chemical synthesis of low bulk density aluminium hydroxide powder

Pradhan, J.K.; Gochhayat, P.K.; Bhattacharya, I.N.; Das, S.C.; Panda, R.K. (Journal Of Chemical Technology And Biotechnology, 78(5), 2003: 577-581)

Fine, low bulk density aluminium hydroxide powdered gel was prepared by the mild base hydrolysis of an aqueous solution of aluminium sulfate with hydrazine hydrate. Parameters such as method of addition of reactant, initial ...
