The effects caused by modifying additives, namely nonionic surfactants (Tween 80 and Neonol AF 9-6) and oxides (B2O3 and HfO2), on the rheology, film formation, and phase formation in the yttrium aluminum silicate system prepared by sol–gel technol

Protective heat-resistance coatings for silicon-carbide materials were synthesized on the basis of compositions in the system Y2O3–Al2O3–SiO2 by the sol-gel method. A procedure for preparing sol-gel solutions was worked out. The effect of the com

We have identified a convenient strategy for the control of the thermal growth of monoclinic Sr-anorthite and tialite phases in Sr-Ti-Al-silicates. The proposed method gives rise to a novel glassceramic material with thermal, mechanical, and dielectr

We show that the activity of silver/aluminum oxide catalysts in selective reduction of nitrogen oxides by ethanol increases as the Al2O3 content increases, and is determined by the optimal silver content for which Ag+ cations and $ {\mathrm{Ag}}_n^{\
