Resistance parameters and water quench test as criteria of thermal shock behaviour of alumina based refractories
(Taylor & Francis Ltd, Abingdon, 1999)
The materials investigated were five alumina based commercial refractories with different contents of Al2O3 + TiO2 from 28 to 78%. Thermal (k thermal conductivity, alpha coefficient of thermal expansion) and mechanical (E ...

On the possibility of incorporating Mn(II) and Cr(III) in SAPO-34 in the presence of isopropylamine as a template
(Butterworth-Heinemann, 1993)
Hydrothermal synthesis of SAPO materials using isopropylamine (i-PrNH2) as the template leads to the formation of MnAPSO-34 if Mn(II) is present. In the presence of Cr(III), the synthesis yields SAPO-34 containing ...
Preparation of Two Cobalt-Substituted Zincophosphate Molecular Sieves
(Marcel Dekker, Inc., 1997)
Two different open-framework cobalt-zincophosphate phases crystallise from the same reaction mixture at ambient conditions depending on the preparative procedure. One of them is a sodalite analogue containing up 70 8 wt.% ...
A novel open framework zincophosphate: Synthesis and characterization
(Elsevier Science Inc., 1995)
The crystallization of a reactive zincophosphate gel (which may contain Co(ll) component) in the presence of sodium cations at ambient temperature and pressure yielded products (abbreviated ZnPO-HEX or CoZnPO-HEX) with a ...

Hydrogen peroxide oxidation on passive iron in alkaline solutions
(Pergamon-Elsevier Science Ltd, Oxford, 1992)
The kinetics of hydrogen peroxide oxidation were studied on passive iron in alkaline solutions of pH ranging from 9.8 to 13.8, using the rotating disk electrode. Measurements were taken using the linear sweep technique. ...
Kristalisanje koncentrovanih rastvora celuloze u N-metilmorfolin-N-oksidu / Crystallization of concentrated cellulose solutions in N-methylmorpholine-N-oxide
(Loznica : Viskoza, 1992)
U istraživanju mogućnosti dobijanja hemijskih celuloznih vlakana bez upotrebe ugljen disulfida posebna pažnja je posvećena takvim direktnim rastvaračima celuloze kao što su tercijerni amini. U ovom radu proučavane su pojave ...
Oxygen reduction on iron-IV. The reduction of hydrogen peroxide as the intermediate in oxygen reduction reaction in alkaline solutions
(Pergamon-Elsevier Science Ltd, Oxford, 1991)
The kinetics of hydrogen peroxide reduction were studied on iron in borate buffered and unbuffered solutions of pH ranging from 8.6 to 13.8, with and without the presence of chloride ions. A rotating disk electrode was ...
